Class 0.5 Transducers

General Details

Crompton Instruments provides an extensive range of transducers providing measurement, isolation and conversion of electrical parameters into industry standard DC output signals. Transducers are 0.5 Accuracy Class. The range offers protection against high voltage and overload, and resistance to vibration in harsh electrical environments. Also offered are multiple analog outputs in a single housing and individual measurement of most electrical parameters.



  • Convert high voltage signals to a low voltage DC output
  • Limit voltage levels to the attached equipment and minimize the possibility of overloads or transients being passed on
  • Provide a signal that can be transmitted from the measuring location to a remote point


  • High protection against overload – 20 x rated current for 1 second
  • High degree of mechanical shock and vibration resistance
  • Protection against high voltage
  • Inputs, outputs and power supply are galvanically isolated
  • Designed for use in harsh electrical environments
