Ethylene detector-transmitter E2638-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 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 relays with closing contact (optional) may be used for remote signalling or concentration control. Two alarm set-points are user settable.
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.
