The GDA 2535 Ethylene (C₂H₄) gas sensor is a 2 wire 4-20 mA Loop Powered device utilising an electrochemical Ethylene sensor unit which is temperature compensated and easily replaceable.

Designed, manufactured and supported locally in Australia.

The Ethylene gas sensor electronics are housed in a robust IP56 ABS sun tolerant plastic enclosure. The sensor element is on a pluggable lead to allow ease of replacement. The sensor head and its electronics are housed in a metal enclosure giving it excellent RFI and EMC compatibility with a splash proof cover giving an IP53 rating.

  • Available in 0-100 ppm, 0-200 ppm, 0-500ppm and other ranges on request.
  • 4-20 mA o/p (For Voltage Output see the GDA 2635)
  • Low cost replaceable gas sensor element
  • Easy to install
  • Easy to calibrate (only gas and multimeter required)
  • ABS sun tolerant IP56 housing with sensor element IP53
  • Australian Factory Certificate of Calibration

Poisoning: GDA sensors are designed to operate in a wide range of harsh environments and conditions. However, it is important that exposure to high concentrations of solvent vapours is avoided, both during storage and operation.
