Oxygen sensor
E2618-O2
Features
- Electrochemical sensor
- Range 0...25 %vol O2
- Resolution 0,01 %vol O2
- 2 × 4-20 mA or 0-10 V, RS485
Description
Oxygen transmitter E2618-O2 is a member of new PluraSens® family of multifunctional measurement instruments. The instrument may be used to prevent critical decrease of O2 concentration as well as to control the absence of the oxygen in gas mixtures. The instrument utilises a fully calibrated and temperature compensated gas sensor with excellent repeatability, stability and long lifetime. Two analog outputs and RS485 digital interface with industry standard Modbus RTU protocol can be used to connect the transmitter to safety or building automation systems.

Description
Combustible gas detector-transmitter E2608-LEL is a member of new PluraSens® family of multifunctional measurement instruments. The device exhibits sensitivity to hydrogen, methane, acetylene, propane and butane. Applications include underground parkings, boiler houses, battery charging rooms, kitchens, and other confined spaces, where potentially explosive concentration of combustible gases can accumulate. The instrument utilises fully calibrated metal-oxide semiconductor or pellistor gas sensors with excellent repeatability, stability and long lifetime. Two relays with closing contact may be used for remote signalling or ventilation 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.
