E2658 series is a new line of flameproof transmitters intended for use in ATEX Zones 2 and 22. 

E2658 series devices are based on PluraSens® multifunctional platform.

Solvent vapors transmitter E2658-VOC is intended to detect ethanol, toluene, xylene and other VOCs.

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

According to user's preferences the detection range may be set to either 0...100% LEL (for fire prevention) or to toxicity range from 0...100 ppm to 0...1000 ppm of target gas.

To connect the detector to safety or building automation systems use two analog outputs and RS485 digital interface with industry standard Modbus RTU protocol.

Two relays with closing contact (option) may be used for remote signalling or ventilation control. Default alarm set-points are typically at 20% LEL and at 50% LEL for 0...100% LEL range and at 100 ppm and 300 ppm for 0...500 ppm range.
