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.

E2658 series is a new line of flameproof detectors-transmitters intended for use in ATEX Zones 2 and 22. The instrument utilises novel fully calibrated and temperature compensated gas sensor with excellent repeatability, stability and long lifetime. To connect the detector to safety or building automation systems use two analog outputs and RS485 digital interface with industry standard Modbus RTU protocol. We recommend to set the output scale within 20-100% of the detection range. Two relays with closing contact (option) may be used for remote signalling or ventilation control. For 0…100 ppm range alarm set-points are 10 and 20 ppm. For 0…2000 ppm range alarm set-points are user settable within 5-95% of the detection range.
