Hydrogen sensor transmitter – non-flameproof, flameproof LEL detector for Zone 1 with ATEX, IECEX, SIL 2 certificate, display, relays

Hydrogen gas detector series is highly robust, industrial grade,non-flameproof, flameproof, or explosion proof gas detector for hydrogen LEL or flammability monitoring. It is used for online, continuous monitoring of hydrogen flammable concentration in %LEL terms in ambient air or in duct or pipeline. It is ATEX EEx’d’ certified with SIL 2 safety integrity level for hazardous area installation Zone 1 and 2.

The sensor transmitter offers linear, proportional analog output in industry standard current signals, over measuring range of 0 ~ 100 % LEL (lower explosive limit). The detector works on highly sensitive catalytic bead based pellistor sensor cell, with low response time. It has unique feature of auto diagnostic watch dog with zero point tracking feature.

Due to its 12-bit microprocessor based control unit, it offer high accuracy over long term. The detector is also equipped with sintered filter with flashback arrestor for enhanced safety.

It also offers optional features like inbuilt LCD display, flashing alarm LEDs, onboard potential free relay contacts (24VDC @ 1 A), RS485 serial interface with Modbus RTU communication.
