Hexane ppm sensor transmitter

Hexane ppm sensor XGST series monitor ppm level toxic concentration in ambient air or in ducts. It is flameproof or explosion proof sensor transmitter with ATEX certified for hazardous area Zone 1, 2 installation. It is ideal for installation in solvent warehouse, edible oil manufacturing, oil cake manufacturing chemical plants, refinery and so on.

It is available with LCD Display, on-board relay contacts, flashing alarm LEDs, auto diagnostic watch dog, non-intrusive calibration, with industry standard linear analog output.


Hexane ppm sensor for toxic detection

fixed, online detection and monitoring of ppm level of hexane gas, flameproof / explosion proof certified Zone 1, 2 – ATEX, SIL 2, with / without display, contact relays, flashing alarm LEDs, RS485 serial interface with Modbus RTU protocol

Model: XGST-255

XGST series hexane gas sensor transmitter is highly robust, industrial grade, flameproof or explosion proof instrument for ppm level detection of hexane gas. Due to toxic and carcinogenic nature of hexane gas, it need to monitor continuously in workplace area for toxic levels, as per OSHA guidelines.

The detector can be installed at walls, surfaces or in ducts for monitoring in gas or air sample. It is ATEX EEx’d’ certified 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 ~ 1000 ppm. The detector works on highly selective electro-chemical sensor cell, with low response time. It has unique feature of auto diagnostic watch dog with zero point tracking feature. Due to its 10-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.
