GWD42 mining intrinsic safety infrared temperature sensor non-contact temperature measurement for coal mine underground use

Description :

  The GWD42 intrinsically safe infrared temperature sensor for mining is a non-contact temperature measurement device designed specifically for harsh environments underground in coal mines. The GWD42 mining intrinsic safety infrared temperature sensor mainly solves the problem of real-time temperature monitoring of key parts such as belt conveyors, rollers, and bearings, and prevents fire accidents caused by friction overheating. Through infrared detection technology, it can accurately capture the surface temperature of the target without interfering with the operation of the equipment. It is suitable for mining conditions with gas and coal dust explosion hazards and is an important component of the mine safety monitoring system.

  The GWD42 mining intrinsic safety infrared temperature sensor follows strict explosion-proof standard design and has an intrinsic safety circuit structure. Its typical measurement range covers -20 ℃ to 150 ℃ (depending on the specific model), and the temperature measurement accuracy is usually controlled within ± 1 ℃ or ± 1%. The shell is made of high-strength flame-retardant and anti-static materials, with a protection level of IP54 or above, which can effectively resist the erosion of underground moisture, dust, and corrosive gases. The GWD42 mining intrinsic safety infrared temperature sensor outputs mostly 4-20mA current or RS485 bus signals, compatible with mainstream coal mine safety monitoring substations, ensuring the stability and real-time transmission of data.

  When selecting, it is necessary to clarify the installation distance and field of view ratio of the GWD42 intrinsically safe infrared temperature sensor for mining, to ensure that the measured target fills the field of view to obtain accurate readings. It is particularly suitable for rotating parts that operate continuously and are difficult to directly contact for temperature measurement. Unlike ordinary industrial infrared thermometers, the GWD42 intrinsically safe infrared temperature sensor for mining has coal safety certification (MA mark), which is strictly prohibited from being used as a substitute in ordinary industrial scenarios without explosion-proof requirements. It is also not suitable for direct temperature measurement behind transparent glass or high reflectivity metal surfaces. If necessary, emissivity parameters need to be adjusted or blackbody patches need to be installed.

  The installation of GWD42 intrinsically safe infrared temperature sensor for mining should be fixed on the bracket to avoid strong vibration causing optical path deviation. In daily maintenance, it is necessary to regularly wipe the surface of the lens with a soft and clean cotton cloth to prevent the accumulation of coal dust from affecting the infrared transmittance. It is recommended to perform zero point calibration and full-scale inspection once a month. If abnormal or fluctuating data is found, the circuit connection and power supply voltage should be checked for stability. Before restarting after long-term disuse, it is necessary to conduct power on preheating and functional testing to ensure that the GWD42 mining intrinsic safety infrared temperature sensor is in normal working condition and to ensure the safety of mine production.
