The rated output (RO) of Interface load cells is the electrical output of a load or torque cell in millivolts per volt of excitation (mV/V) at the rated load. For example, the electrical voltage output of an Interface load cell with 4 mV/V at 5,000 lbs rated capacity will typically be 4 mV ± 10% or 3.6 mV/V to 4.4 mV/V. In certain applications, it could be desirable for a customer to receive cells with a tighter output tolerance. For a minimal cost, we can “standardize” the outputs within ±0.1% of the rated outputs shown in the catalog (example: 4 mV/V output would be standardized from 3.996 mV/V to 4.004 mV/V).

As a result of the trimming operation, the input resistance of the load cell may be increased. A maximum resistance on a 350 ohm bridge would not exceed 405 ohms.

Application Considerations & Benefits For Wanting Standardized Output:

Convenience:
Volume users who do not wish to trim their electronics for each individual load cell.


Interchangeability:
Any customer who wishes to interchange load cells without adjusting instrument.


Summing:
Multiple cell installations (a wei***ridge) where the cells are wired in parallel and the
outputs summed.
