Gefran CIR Strain gauge transducers amplifier

GF-CIR

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

  • Linearity error < 0.02% FSO
  • Voltage or current output
  • Low thermal drift < 0.01% FSO/°C
  • Compact size
