GWH100 Mining intrinsic safety infrared temperature sensorDetailed product description：

The GWH100 intrinsically safe infrared temperature sensor for mining is suitable for use in explosive gas environments containing gas and coal dust underground in coal mines, and is used in conjunction with the host of the explosion-proof and intrinsically safe belt conveyor protection control device for mining. Temperature detection and protection of the reducer high-speed shaft, motor casing, transmission drum bearing seat, and other components of the coal mine underground belt conveyor belt can also be used in non explosion proof environments on the ground.

Main parameters of GWH100 intrinsically safe infrared temperature sensor for mining use
Working voltage: DC12V-24V;  
Alarm setting: adjustable between 0 ℃ and 100 ℃, with an error of ± 1 ℃;  
Passive contact output: When disconnected, the output terminal resistance is ≥ 100K Ω, and when closed, the output terminal resistance is ≤ 10 Ω;  
Analog signal output: DC current (4mA~20mA) corresponds to a temperature range of 0~100 degrees;  
RS485 signal output: Execute Modbus protocol;  
Response time: ≤ 2s
The detection distance of the probe is 1.6:1 compared to the object distance;

Functional characteristics of GWH100 intrinsically safe infrared temperature sensor for mining

The circuit adopts modular design, overall packaging, small size, and light weight;  
After the temperature sensor is connected to the intrinsic safety power supply, the LCD screen lights up, indicating that the temperature sensor has entered the detection state. In the detection state, the temperature of the object being measured is constantly monitored. During the detection process, when the temperature of the object exceeds the set value, the relay closes and the host can collect the status. The host opens the sprinkler solenoid valve based on this signal to spray water and cool down the overheated components;  
Parameter settings can be made through the remote control;
