Dpstar is an authorized distributor of Evikon. Evikon is an instrumentation company, specializing in the development, manufacturing, and marketing of sensor-based electronic measurement instruments for industrial and building automation applications. Our mission is to provide businesses and organizations with convenient and efficient technical solutions for the measurement of environmental parameters and control of processes – temperature, pressure, level, humidity, and moisture, toxic and explosive gases – to help save resources, increase production quality and ensure safety.

Combustible gas detector-transmitter E2638-LEL is a member of new PluraSens® family of multifunctional measurement instruments. The device exhibits sensitivity to hydrogen, methane, acetylene, propane and butane. The instrument utilises a fully calibrated metal-oxide semiconductor gas sensor with excellent repeatability, stability and long lifetime. 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 connect the detector to safety or building automation systems.

Dimension

Applications

  • Underground parking
  • Boiler houses
  • Battery charging rooms
  • Kitchens
  • and other confined spaces, where potentially explosive concentrations of combustible gases can accumulate.
