Ethylene Detector-Transmitter

  • Stable long-life electrochemical gas sensor
  • Ranges 0...10 / 0...200 / 0...1500 ppm C2H4
  • Resolution 0,1 / 1 / 5 ppm C2H4
  • Attached or remote sensor
  • 2 × 4-20 mA / 0-10 V, RS485
  • Two SPST relays


Ethylene detector-transmitter E2638R-C2H4 is a member of new PluraSens® family of multifunctional measurement instruments.

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

The instrument utilises novel fully calibrated and temperature compensated electrochemical gas sensor with excellent repeatability, stability and long lifetime.

To connect the detector use two analog outputs and RS485 digital interface with industry standard Modbus RTU protocol.

Two relays with closing contact may be used for remote signaling or ventilation control.  The flashing LEDs and an internal buzzerб available as an option, give alarms as well at two set-points.
