Mining infrared temperature sensor

1、 The GWH60 mining infrared temperature sensor is an intrinsically safe electrical equipment for mining, suitable for use in environments with gas and coal dust explosion hazards in coal mines. It is used in conjunction with the KHP183-Z coal mine belt conveyor comprehensive protection device host to measure the temperature at the detected location of the belt conveyor and output switch signals.

2、 Main performance

1. Action temperature:

60℃±2℃

2. Output signal:

a、 Switching signal, high level ≥ 9V, low voltage output ≤ 3V level signal.

b、 Analog signal, 4-20mA

3. Intrinsic safety parameters:

Ui：12V DC Ii：30mA Ci：0 uF Li: 0 mH

4. Introduce cable model specifications: The distance between the sensor and the host is 1km, using a mining rubber sheathed cable with a distributed capacitance of less than 0.1 μ F/km and a distributed inductance of less than 1mH/km.

3、 Structural features and working principle

Any object radiates infrared energy outward, and the radiation intensity varies with temperature. Infrared temperature sensors use infrared temperature measuring components that receive infrared radiation and convert it into electrical signals. They have good linearity, stable operation, and a small detection error range,
