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 E2658R-PID utilises highly sensitive photoionization detectors (PID) with extremely low minimal detection levels. The transmitter exhibits sensitivity to compounds with ionization potential less than 10.6 eV, i.e. to most solvent vapors.
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. Two alarm set-points are user settable.
