resistance calibrator / for strain-gauge amplifiers / high-precision / desk

The manual strain gauge calibrator is used for simulation of
strain gauge sensors with bridge resistances of 120 W, 350 W or
1000 W. Other bridge resistances or the combination of up to 2
bridges in one housing are available on request. The device is used
wherever strain gauge amplifiers need to be tested or calibrated.
The sensitivity setting is done by parallel connection of resistances
to a shunt arm. For switching of polarity the shunt circuit is reversed.
Sensitivity settings and switching of polarity are done manually with
high-precision switches.
