Decide

Not sure which one? Two ways to narrow it.

Size it for me

Give us the load you actually need to weigh or pull. We will size the load cell against it and name the model, using the same rule our engineers use.

The heaviest load on the load cell in normal use, including anything hanging with it.

The threaded holes it mounts through, and the rod ends, eye bolts and hardware that screw into them. Search any size. Our standard sizes narrow the answer below, and one we do not carry goes straight to an engineer as a custom build.

Pre-filled with a 1,000 lb example. Type over it. We add 1.25× headroom, then match the nearest rated capacity in a family that meets the rest of your answers. Genuine shock and impact wants more than either: send us the details and we will size it properly.

Every NTEP load cell at a glance

Both families on one screen: certified range, nonlinearity, load direction and price. Model names go to the product pages.

Alternatives

Not selling by weight? Try these.

The certificates cover the BSS from 250 to 2,500 lb and the SBS from 1,000 to 10,000 lb. For any other capacity, or where nothing is bought or sold by weight, the full families have more to choose from.

The NTEP load cell reference.

What the two certificates cover, why the finished scale needs its own, and where each load cell belongs.

The certificates

Certified by capacity. Not by series.

NTEP evaluates a load cell as a type and lists the capacities it covers. That is why only part of each family is on this page.

What NTEP is

NTEP is the National Type Evaluation Program run by the National Conference on Weights and Measures. It evaluates a weighing component as a type (not each unit) against NIST Handbook 44, and issues a Certificate of Conformance describing exactly what was tested. Where a scale determines a price or a quantity in commerce, every element in the chain needs one.

The two certificates

The BSS carries NTEP CoC 97-028 on capacities from 250 lb through 2,500 lb. The SBS carries NTEP CoC 95-146 from 1,000 through 10,000 lb. The store’s option labels agree: exactly those ratings are marked NTEP.

Above and below those bands, both families are the same part, built the same way to the same specification. They sit outside the evaluated type, though, so a scale built on them cannot be sealed for trade however well it performs.

The scale

The load cell is certified. The scale still has to be.

A certified load cell is one element. The indicator and the finished scale have their own path.

One element in the chain

The certificate covers the load cell, not the finished scale. The indicator and the system have their own path, and one uncertified element breaks the chain. The finished scale still has to be sealed by a weights and measures inspector.

A certified component does not make a certified system either. Accuracy in service is the sensor, the mounting, the electronics and the calibration procedure together, and the weakest of the four sets the result.

Choosing

S-beam or shear beam. The load path decides.

Both are certified for trade. They take load differently, so the structure being weighed picks between them.

BSS: hanging and suspended loads

An S-beam takes load axially through threaded connections at both ends and reads tension and compression with the same part. Mounted inline between hook and load, the reading is the suspended weight itself, which is why S-beams carry crane and hanging scales and suspended tanks and hoppers. Across its certified band the BSS threads 3/8″-24 UNF to 250 lb and 1/2″-20 UNF above.

SBS: four corners of a deck

A single-ended shear beam bolts down at one end and takes load through a threaded hole at the other, in compression. Four under a steel deck, summed in a junction box, is the standard floor and platform scale, and the SBS at 1,000 to 10,000 lb per corner is the part that can be sealed. It threads 1/2″-20 UNF from 1,000 lb to the small-envelope 5,000 lb, and 3/4″-16 UNF on the large-envelope 5,000 lb and the 10,000 lb.

The questions worth asking.

Is every BSS and SBS capacity legal for trade?

No. CoC 97-028 covers the BSS from 250 through 2,500 lb, and CoC 95-146 covers the SBS from 1,000 through 10,000 lb. The other ratings in both families are built and specified identically but sit outside the evaluated type, so they cannot be used in a scale sealed for commerce.

Does an NTEP load cell make my scale legal for trade?

Not on its own. The certificate covers the load cell. The indicator and the system have their own path, and the finished scale still has to be sealed by a weights and measures inspector.

Is the stainless SBSB certified?

No. The SBSB carries no NTEP certificate at any capacity. It is the washdown and corrosive-process shear beam; the SBS is the trade one.

Do I need NTEP for process control or testing?

Usually not. NTEP matters where weight is the basis of a sale. For process control, testing and internal measurement, non-NTEP load cells are usually the better value, and the full S-beam and shear beam families open up.
