Fitness Equipment Company Gives Doran Scales a Workout

Posted on by

Recently, a fitness equipment manufacturer was weighing a kit of parts and their current weighing system was still allowing an unacceptable quantity of quality control problems. The ideal product for the fitness company was a Doran 2200cw scale. Below is a summary of what was installed at their facility.

A system was proposed that would automate and simplify the process and retain the accumulated weight through the process of weighing several components of a parts kit. By connecting three Doran 2200CW over under accept check weigh scales together and using foot switches to activate certain push buttons, Doran was able to construct a system that allowed the employees to accurately weigh the kit of parts even though the weighing process took place across three workstations – all without pushing buttons on the scale front panel.

2200CW check weigh scaleThree 2200CW check weigh scales were set up using RS-232 cables so that scale number one sent weight data to scale two, and scale two sent weight data to scale three. The first 2200CW check weigher was set up for an over value of 1.2 lb and an under value of 0.7 lb. The employee weighs the items at the first scale and then presses the PRINT foot switch on the first scale. That weight is sent to the second 2200CW and would be automatically programmed as the tare value in the second scale.

The second 2200CW scale is set up with a target weight of 2.2 lb. A component is added to the kit of parts and would be weighed on the second scale and the GROSS/NET foot switch would be pressed to change it to gross mode. The PRINT foot switch is pressed and the total weight (including the tare value sent from scale one) is transmitted to scale three.

On the third and final 2200CW scale, another part is added to the kit. The GROSS/NET foot switch is pressed, to put the scale into gross mode. The weight of all the parts is shown on the display of scale three.

This is just one example of what is possible with Doran scales and the huge choice of available options. If you have a unique weighing application, contact us at Central Carolina Scale and we can get a Doran scale system quoted for you that will save you money and increase your efficiency.

Legal For Trade Price Computing Scales State Testing Info You Can Use

Posted on by

legal for trade price computing scaleEvery year dozens and dozens of our customers either purchase new retail scales or they have their current legal for trade scale calibrated or certified. These are typically scales they can use at places like the farmers market to sell their fruits and vegetables by the pound. Basically any device used where items are bought or sold by weight is typically required by most state’s laws to be inspected and certified. This would include a counter top scale at a farmer’s market (or mechanical hanging scale) that is used to weigh produce that customers want to buy. Of course, inspecting a retail scale is an advantage to both the farmer and the customer.

I’ve mentioned this in the past but if you are buying or selling your items based on weight, you want to make sure that you purchase a scale that has NTEP approval. The certificate of conformance or CoC# should be on the side of the scale. The article below is also a good resource.

Keep in mind that no device is perfect and must be adjusted periodically. It is also recommended that you do not buy cheap quality scales that will likely not last. There are regional inspectors located across the state that will coordinate with the marketer to complete the certification. The inspectors have a set of standard weights calibrated annually for correctness. They will use these weights to test the marketer’s scales. Once you scale has been inspected you need to recertify every two years.  If the scale is out of tolerance (deemed inaccurate) a scale repair service must fix the scale or a new unit must be purchased.

Can I Buy An American Made Floor Scale?

Posted on by

Over the past few months on this site we have taken a look at how realistic is it to purchase certain types of scales and related equipment that is actually made in the USA. We looked at Made In The USA scale indicators and Built in America Load Cells. Today I wanted to find out if you can still buy a Made In the USA floor scale?

Absolutely! Now I do want to write a small disclaimer before I get started. The information presented below is provided to the best of my knowledge and at the time of this writing is true. As all of you know, the pressures of a shaky economy and increased competition can always force scale manufacturers to change their process. But to my knowledge what I’m writing below is accurate regarding these decks being made in the United States. So with that being said, let’s answer the simple question. Can I still get a floor scale that was actually built in America? Yes you can.

Anytime you think of floor scales built in America the first choice has to be the Pennsylvania Scale 6600 series. The Pennsylvania floor scale is built in either Lancaster PA or at the corporate facility in Terre Haute, IN. These scales are well built and feature an outstanding warranty. As an added bonus, the indicators from Pennsylvania are also made in the USA. Continue reading →

Best Practices For Calibration Test Weights

Posted on by

Rice Lake’s Metrology department has retained its world class reputation through its highly trained staff and adherence to stringent handling procedures–from receiving, to calibrating, to shipping. The information below from Rice Lake highlights the standard procedure that they use upon receipt of your test weights. Here you’ll also find the best practices that Rice Lake recommends for handling weights and standards to help you maintain the best quality and integrity of your weights.

Recommended shipping procedures for weights
Ship weights in cases and materials designed to withstand and repel the abuses of shipping.
Packaging peanuts should not be used with weights, as this type of packaging clings to the weights creating static electricity which can compromise the lab environment.
Alternative packing material is recommended as follows:
Styrofoam (not peanuts or smaller pieces)
Paper (not shredded as this also conducts static electricity)
Bubble wrap
Loose small weights should have crumpled paper (not shredded) packed soundly in between all weights and box.
Clean room cases should only be used for weight storage and are not recommended for the shipment of weights.
Shipping of heavy weights (10 lb or larger) in cardboard boxes is not recommended.
Larger weights should be individually wrapped or protected, supported with stiff packing material and double boxed for structural durability.
Small weight kits should be held shut with secure latches, rubber bands, or tape, and placed inside boxes or bags.

Rice Lake Weight Handling Procedure
All weights and cases are inspected for damage and scheduled for calibration upon arrival to the lab.
All stickers and marker are removed from the weights.
Precision weights receiving NVLAP Calibration are checked for magnetism.
A tolerance test is conducted.
Any follow up with the client is completed.

Required Standards Conditions
* All delivered standards to this laboratory are required to arrive with the following conditions:

All weights should be clean and in good repair.
Any cleaning, repair, or painting of standards in the metrology lab will incur an extra charge.

Mass Standards
Weights should be clean and in good repair.
Weights shall be identified with a permanent serial number or mark into the surface of the weight.
Stickers and marker are not allowed and will be removed. The added mass of the sticker may change the mass of the weight, possibly causing the weight to be out of tolerance which will invalidate the reported value on the certificate.
Individual weight kits shall also be identified with unique serial numbers.
Cast iron weights should have no evidence of rust, loose paint or adhering debris.
Analytical weights should be handled carefully. Tolerances are small, so dirt or abuse can throw them out of tolerance.

Cases
Interior of cases for weight kits should also be wiped out or vacuumed.
Cases should be sound with secure latches.

So You’re Looking For Cheap Veterinary Scales?

Posted on by

Quite often we are asked for a set of “cheap vet scales to weigh my ______ (fill in the blank)”.  It could be dogs, cats, llama, alpaca, pigs, sheep, goats, etc… Unfortunately these days when you say the word cheap or affordable or low cost, you almost always have to supply scales that are made in China. And of course when you talk about electronics from overseas, you can get a wide range of quality.  As for made in the USA, we don’t really have many choices for American Made veterinary scales if anyone is interested, but they are more expensive.

So, assuming you still want to stick with the “affordable” vet scales, let’s take a look at a few of the imported vet scale models currently available that we like.

Cheap Veterinary Scales

The Weighsouth VS-2501 vet scale is a heavy duty vet scale that is a really good scale for many applications. This scale is well built and one of our favorites in this market. The price is good and the quality and durability have been impressive. As you can see from the pictures in the link above the scale has a nice digital indicator and adjustable feet.

The Brecknell line of animal and livestock scales is very impressive. They have several smaller scales for weighing small animals. They have three different sizes of the PS500 which are great for vet hospitals. If you need a larger platform and capacity, they offer the PS1000 which has a 1000 pound capacity and 55″ x 20″ platform, the PS2000 which is a larger 59″ x 30″ platform with 2000 pound capacity and the PS3000 with 3000 pound capacity and 39″ x 78″ platform.

The LVS 700 digital scale is an affordable choice especially for individuals looking to weigh their animals at home. The scale is easy to use and the display is easy to read. We have the standard size of this scale and we also have a “Extra Large” version of this scale which is slightly bigger. The platform has small wheels on one end and a handle so it can be carefully transported to another nearby location if needed.

So which vet scale should you purchase? Our suggestion is to contact us and we can walk you through the pros and the cons of each animal scale that we offer. We have sold all of these scales over the years and have experience with them, either directly or through our customers reviews. Give us a call and we can review each of the items with you and make sure that you get the correct vet scale for your particular application.

Is It Alright To Cut Load Cell Cable?

Posted on by

A customer recently asked us about cutting load cell cable because the cable was too long for his particular application.  The standard line of thinking is that you should not cut load cell cable because it may void the manufacturer’s warranty. Are there any recommendations for altering load cell cable that might be different than cutting?

Actually, there are several things you can do in these types of situations. Many load cell manufacturers recommend NOT altering (shortening) the load cell cable length, and most manufacturers will not honor the warranty on altered products. However, for the majority of load cell installations, any output change resulting from cable length alteration is easily compensated for with a junction box with trimming capability. Excess cable should be coiled and secured within the junction box (if it will fit.) 

If the excess cable will not fit inside the junction box, it will need to be coiled, and secured externally to the junction box with wire ties, or other suitable means. If the cables are routed in conduit, and excess cable will not fit within the junction box, then the only option may be to cut the cable(s) to length.

load cell cable

What if the load cell cable is too short? Well, we recommend avoiding splicing when possible; however, if you need to gain cable length, it is very important to use the correct splicing technique. Ensure the integrity of the cable is maintained, including voltage, current (signal) ratings, shielding, moisture resistance, and tensile strength. Our recommendation is to use a potted cable splicing kit when possible. If you need a reusable splice point, a sealed junction box may be used.  We hope this helps you understand shortening and lengthening load cell cable for specific applications.

The Latest Pennsylvania Scale Update

Posted on by

We just recently received this update below from Pennsylvania Scale. So we figured that we’d share the update in a simple top 10 list kind of like you might see on late night tv.

Number ten is LOAD CELLS. We sell a lot of load cells. Due to that volume, we can offer attractive pricing for cells such as TANK MOUNTS, S-TYPES, ALTERNATIVE CAPACITIES, TENSION MOUNT KITS, etc. If you are shopping for load cells for your customers,  service facilities, or special projects, please contact us a quotation!

Number nine is SHIPMENTS. The factory just upgraded and added UPS new service for larger-than-parcel but smaller-than-LTL freight packages. This service is ideal for 6400’s and M64’s which are pushing 100 lbs. So if you order a Pennsylvania Scale item, please mention “the new BEST WAY shipping”, and we will automatically upgrade the shipment to the most efficient cost-effective way, including UPS HUNDREDWEIGHT or the new service.

Number eight is FREIGHT DISCOUNTS. The factory in Lancaster PA has some amazing outbound freight rates from popular carriers. Unlike some of the competition Pennsylvania does pass along the outbound volume discount for PREPAY & ADD shipments. You may be very surprised!

Number seven is BAGGAGE SCALE ELECTRONIC KITS are once again hot items as government and aviation spending is finally coming back. 1-4 displays. Keep the existing platform and do both your customers and yourself a huge favor and upgrade to more reliable and serviceable M64 electronics.

Number six is PANEL MOUNT OPTIONS for scale indicators. We have a new design that allows retrofitting of panel-mounted indicators fitting the cut-outs for both the former UMC-600 and UMC700 models as well as the smaller openings for the original UMC-555 models, making exact field replacement easy and efficient. Contact factory for details.

Alright we’re half way home. Number five is HIGH RESOLUTION WEIGHING, many distributors are replacing overcomplicated and hard-to-use “foreign” indicators with Pennsylvania 7600 series indicators in high resolution applications. You can easily ‘push’ resolution on Pennsylvania scales and meters due, in a large part, to the premium A-D converter they use… If you need to add utility and simplify life for your maintenance technicians as well as your employees, try using 7600+ or 7600E units.

Number four is non-standard resolutions and weight units can be easily handled at the factory—including ‘pushed’ resolution (non-NTEP), double/triple ranging, special units of measure (PRIMARY/SECONDARY units—specify with order, n/c). Like a certain fast food burger chain likes to say, special orders don’t upset us – all we ask is that you let us build it your way!

Ok, number three is FAST SHIPPING AND STOCK SHIPMENTS. The factory has added staff and efficiency in Lancaster. Most standard products ship from STOCK or 1-2 day delivery. IF YOU need equipment right away, please ask, we can often get scales and spare parts quickly. Continue reading →
