GT-CDI2950DEx Industrial and Commercial Point-Type Flammable Gas Detector
1.Product Overview
This product is an explosion-proof device, suitable for Zone I and Zone II environments where there may be leakage or explosion hazards of flammable or toxic and harmful gases in industries such as petroleum, chemical engineering, gas storage stations, and wine factory production workshops. It is not applicable to Zone 0 or underground coal mine environments. The detector can conduct safe detection and give advance alarms for gas leakage accidents.
The detector features TFT liquid crystal display, infrared remote control, three-wire 4mA-20mA output, RS485 bus communication (Modbus RTU protocol), and passive contact output functions.
2.Product Features
(1) Adopts a segment LCD display with infrared remote control function, making debugging convenient.
(2) Uses a thermistor sensor, enabling maintenance personnel to replace all sensors in the entire site easily.
(3) Equipped with sound and light alarm function. When detecting combustible gas leakage, the detector will issue a harsh sound and light alarm to avoid.
(4) Has zero-point correction function, which can avoid measurement errors caused by zero-point drift.
(5) Features a standard RS485 interface based on the Modbus (RTU) protocol.
(6) Can be matched with JB-QB-CH210 combustible gas alarm controller, PLC, DCS and other systems for use.
(7) Adopts a single-chip microcomputer processing system, which has stable performance, strong anti-interference ability and low power consumption.
