Hysteresis and non-repeatability is .02%; creep and non-linearity is .03% of full scale!! 
This means for a 4000 pound load cell you can get accuracy to 1.2 pounds!

Nickel plated steel construction with 50 feet of shielded cable. 
Brand new, in the box, never used!  Includes calibration certificate and QA data from factory.

Simple to mount on most any test stand.

An entire system can be constructed, one piece at a time, from   basic modules.

Parts of a system can include: 

• Load cells 
• Cable 
• Junction Box (summing up the load cell signals up to one output),
• Instrumentation (indicators, signal conditioners, etc), 
• Peripheral Equipment (printers, scoreboards, etc.)

The strain gage is the heart of a load cell. A strain gage is a device that changes resistance when it is stressed. The gages are developed from an ultra-thin heat-treated metallic foil and are chemically bonded to a thin dielectric layer. "Gage patches" are then mounted to the strain element with specially formulated adhesives. The precise positioning of the gage, the mounting procedure, and the materials used all have a measurable effect on overall performance of the load cell.
 
 

Each gage patch consists of one or more fine wires cemented to the surface of a beam, ring, or column (the strain element) within a load cell. As the surface to which the gage is attached becomes strained, the wires stretch or compress changing their resistance proportional to the applied load. One or more strain gages are used in the making of a load cell.

Multiple strain gages are connected to create the four legs of a Wheatstone-bridge configuration. When an input voltage is applied to the bridge, the output becomes a voltage proportional to the force on the cell. This output can be amplified and processed by conventional electrical instrumentation.
