Quote NowThe Fixed point-type gas detector is a new type of online detection instrument independently developed and manufactured by our company. It is equipped with a high-brightness digital display, high-decibel audible and visual alarms, and high-performance imported sensors.
Detection Principles: Electrochemical, catalytic combustion, infrared, PID, semiconductor, etc. It can detect more than 500 types of gases. Featuring stable performance, high accuracy, long service life and easy operation, this product is suitable for industrial sites such as oil refineries, chemical plants, liquefied gas stations, gas-fired boiler rooms, gas stations, paint spray booths and so on.
The point-type gas detector converts the gas concentration in the air into digital signals, and can output standard (4~20) mA current signals, or two-wire/ four-wire RS485 (MODBUS-RTU) signals. It is compatible with secondary instruments, PLC and DCS systems, as well as data acquisition modules, with the characteristics of long transmission distance and excellent anti-interference performance.
Dust-proof, explosion-proof, anti-static, reverse connection protection, anti-interference and surge protection functions;
Adjustable detection accuracy and measuring range;
Long service life, high sensitivity, low drift, stable and reliable operation;
Sensor fault self-check, two-stage concentration alarm, with relay output function;
LCD display / digital display and working status indication;
Automatic zero tracking, automatic temperature compensation, over-range concentration protection and multi-point calibration function;
Supports 2-wire (PowerBus), 3-wire (4~20mA), 4-wire (RS485) signal outputs, as well as multiple output modes including LoRa / 4G (wireless versions customized upon request);
IoT signal output, capable of uploading data to PLC, DCS and cloud platforms;
Infrared remote control allows parameter adjustment of detector without opening housing, safe and convenient;
Pluggable modular sensor design for easy maintenance; Flameproof structure, suitable for Hazardous Zone 1 and Zone 2.
This product is suitable for industrial sites such as oil refineries, chemical plants, liquefied gas stations, gas-fired boiler rooms, gas stations, paint spray booths and so on.
