Fixed-Type Combustible Gas Detector With Display And Alarm

Overview

Gas detector adopts advanced catalytic gas sensor or electrochemical sensor, which can translate the gas concentration in the air to the digital signal output. The detector working with gas controller can be used to detect gas in refinery, chemical plant, LPG station, boiler room, painting plant and other places with gas exists.

Main Technical Specifications

Detection Principle	Catalytic / Infrared
Sampling Method	Natural Diffusion
Display Mode	Digital Tube / LCD
Status Indicators	Three LED lights indicating power, and two alarm levels
Environmental Temperature	-20°C to 70°C
Relative Humidity	<95%
Explosion-Proof Type	Flameproof
Explosion-Proof Grade	Ex dⅡC T6 Gb
Power Supply	24V DC
Output Signal	4-20mA / RS485
Switch Quantity	Two (normally open at two alarm points)
Power Consumption	≤5W

Working Principle

Catalytic combustion-type combustible gas detectors use the change in resistance of an infusible platinum wire when heated to determine the concentration of combustible gases. When combustible gases enter the detector, they cause an oxidation reaction (flameless combustion) on the surface of the platinum wire. The heat generated increases the temperature of the platinum wire, causing its resistance to change. By measuring this resistance change, the concentration of the combustible gas can be determined.

Features

This product features a long lifespan, high accuracy, high sensitivity, and low drift, ensuring stable and reliable operation.
It includes a sensor fault self-diagnosis and dual-level concentration alarms with relay output functionality.
The gas concentration and operational status are displayed digitally on an LCD or digital tube.
Equipped with temperature compensation and automatic zero calibration, it supports 4-20mA or RS485 digital output, allowing integration with DCS and PLC systems.
The infrared remote control enables adjustments without opening the cover, enhancing safety and convenience.
Designed with explosion-proof features, it is suitable for hazardous areas Zone 1 and Zone 2.
