Main features & Overview


The CIR-D voltage or current amplifiers have been designed to enable the user to adapt non-amplified strain gauge transducers (load cells, pressure transducers) to acquisition systems, PLC, instrumentation with high level inputs.

These amplifiers have galvanic isolation between the supply voltage and the transducer to increase the rejection of noise generated by the power supply itself.

The availability of the output in current enables the signal to be carried over long distances or used in intelligent automation systems.


  • Galvanic isolation between the Supply Voltage and the Amplifier > 500 Vdc
  • Linearity error > 0.02% full scale output
  • Current output 3-wires
  • Low thermal drift < 0.01% full scale/°C
  • 10Vdc transducer supply
