Ethylene Transmitter
  • Humidity compensated electrochemical sensor
  • Range 0...10 / 0...200 / 0...1500 ppm C2H4
  • Resolution 0,1 / 1 / 1 ppm C2H4
  • 2 × 4-20 mA or 0-10 V, RS485

Ethylene transmitter E2618-C2H4 is a member of new PluraSens® family of multifunctional measurement instruments.

Applications include chemical and polymer industry, agriculture and other areas requiring precise measurement of ethylene concentration.

The instrument utilises a fully calibrated and temperature compensated electrochemical gas sensor with excellent repeatability, stability and long lifetime. Due to a special technical solution for humidity compensation (available as an option), the detector  may be used even at humidity levels up to 100% RH.

Two analog outputs and RS485 digital interface with industry standard Modbus RTU protocol can be used to connect the detector to safety or building automation systems.
