Load Cell Sealing

Posted on by

There is more to a load cell than is it an alloy steel load cell or stainless steel load cell?  Load cells also have a lot of different sealing types. What’s the difference? How do you choose what load cell to buy?

The majority of us aren’t industry experts on load cell production. But when you comprehend the fundamentals subsequently selecting the best one will be considerably less difficult. Let’s begin with straightforward weighing jobs. At the very least, the majority of load cells are environmentally sealed. What does that suggest? It implies that the internal gauge area is protected with potting, and determined by design you might find either a rubber boot or glued metal plate guarding that location too. Environmentally sealed load cells are designed for simple indoor/outdoor use-not frequent moisture contact. You’ll see these cells produced from a variety of material; aluminum, alloy or stainless-steel. Continue reading →

Common Questions Answered Regarding Counting Scales

Posted on by

Counting Scales are very similar to other scales in terms of weighing, but the counting scale does two additional functions, by performing operations in division and multiplication based on the internal resolution.  Please continue reading below as Jim Daggon and Ann Crowley from Rice Lake Weighing Systems answer some of the common questions relating to counting scales like the Digi DC-300, Digi DC-190, DC-788 and the DC-782.

1. What is internal resolution?
The internal resolution of a counting scale is the number of divisions into which it divides the total capacity of the scale.

Example: A 50 lb counting scale with 1 million count resolution divides up the 50 lb into 1,000,000 parts. This means each internal resolution is translated to 50/1,000,000 or 0.00005 lb.All of the weights are calculated on this basis. For example, if some parts were placed on the counting scale, and the internal calculation was 210 internal counts, the weight to be displayed would be 210 times 0.00005 lb = 0.01050 lb. Since the weight display might only be five digits, then the weight display would be 0.01 lb. This is the external resolution. (rounded off).

The operator can key in the sample quantity—for example, ten pieces. The scale still “knows” how many internal counts are being used (210) and now divides that number by 10 to get the number of internal counts per piece (210/10 = 21). Continue reading →

Floor Scales 101 the Fine Print or should we say chinese print?

Posted on by

From time to time we hear from folks asking us about 4’x4′ floor scale systems priced well under $800 with FREE SHIPPING.  Can you truly get a quality 4’x4′ floor scale system for that price?  OR LESS!   Just take a stroll around the internet and you see all kinds of offers.  Well as it turns out, we happened to get a couple of these beauties in our shop to look at.   By the way, they were brought in for repair.

First, almost all of these low cost floor scales are not the size they are promoted to be.  They’re 44″x44″ or 47″x47″.  And that is just the top plate. Once you measure the actual supported frame underneath the top deck plate, that low cost “4×4″ floor scale that you thought was such a great deal is now really a 46″ x 46”.  One of the scales we had in our possession had no label on it.  Who Continue reading →

Become more efficient with a fork lift scale

Posted on by

Rice Lake CLS model fork lift scales are factory calibrated and delivered with innovative packaging that allows safe and fast installation. Compatible digital indicators can accept data wirelessly from the two-channel digital iQUBE® junction box, located on the scale carriage. Or, if you choose, the wired version communicates weight data via the coil cable provided with the scale. For wireless versions, the communication electronics are protected in enclosures mounted to the back of the indicator and in the junction box. Both models are designed with a separate on/off switch to conserve forklift power and will display battery hours remaining before a recharge is needed.

The CLS has a 5,000 lb capacity that is electronically and mechanically supported by two 5,000 lb stainless steel load cells and mechanical overload protection. The centering pin is welded directly to the scale instead of using mounting bolts that often break. The welded centering pin ensures proper Continue reading →

Medical Scales

I took a tour recently of a local pediatrician office. Unlike the other people on the tour, I was actually sneaking a peek at what scales the doctor’s office had.  I was able to see a digital Detecto Medical scale along with a couple of digital baby scales. There was also a separate stand alone height rod in the weighing station for the kids.  All the weighing equipment seemed to be in good condition and it appeared that the scales had calibration stickers on them stating that the scales had been checked for accuracy on a consistent basis.

FLOOR SCALE PRICES

Posted on by

The price of mild steel used in the manufacture of Pennsylvania M6600 Floor Scales rose considerably in 2008. It is difficult in a world market where steel demand drives up the price of the Pennsylvania “Made in the USA” floor scales and meanwhile inferior “no name” products are dumped in the market, putting enormous price pressure on everyone as well. For example, the steel structural extrusion material that is used in the most popular 48″ x 48″ Pennsylvania floor scale designs has DOUBLED in cost since January 2008 — and they use 16′ of it in each and every 4×4 scale. A few comments about the Pennsylvania floor scale design and marketing philosophy:

  1. Pennsylvania will not cheapen the M6600 floor scale to match the competition. The floor scale Continue reading →
