90 kip Capacity Load Cells

The load cells mentioned below are designed for 90 kip loading capacity. The designation number on each load cell is defined as follows: LC (load cell) - A (aluminum) - # (capacity, kip) - # (consecutive no.) - # (cross section area, in2) - # (inner diameter, in) - # (length, in).

Designation Number

Outer Diameter (in)

Excitation Voltage (V)

Resistance for Balance Resistor (kΩ, between B and D)

Calibration Equation:

Calibration Data (VDC)
Uout= UcalA UcalB
