Description

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

E2658 series devices are based on PluraSens® multifunctional platform.

Ammonia detector-transmitter E2658-NH3-S utilises novel fully calibrated and temperature compensated metal-oxide gas sensor with excellent repeatability, stability and long lifetime. 

To connect the device 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.
