Jining coal with temperature sensor GWD100 massive supply temperature sensor GWD100 Main features: First, use GWD100 coal with temperature sensor (hereinafter referred to as the sensor) is to meet our need for coal mine monitoring downhole temperature and developed. It can continuously and automatically be converted into a standard electrical downhole temperature transmission to the mating equipment, and has a local display gas concentration, overrun sound and light alarm. Sensor proof test by the state authorities for online examination, can be used with various types of monitoring system supporting domestic use. Coal safety certificate, safe and reliable. Second, the model implications, explosion-proof type and logos GWD 100 main parameters, measurement range: (0 ~ 100); second feature code, it works: electrical; first feature code, measure the temperature with; Product Type Code: sensors. Mine explosion-proof type of sensor is intrinsically safe, explosion-proof mark "ExibI Mb". Three, dimensions, quality and materials a) Dimensions: 270 × 155 × 55mm b) Weight: ≤ 1.3kg; c) Housing material: Stainless steel. Fourth, the main features 1. Using new highly integrated single-chip microcomputer and digital circuits, the circuit structure is simple, reliable performance, easy maintenance and debugging. 2. Infrared remote control adjustment to achieve the offset, sensitivity, alarm point other features that make adjustment easy and convenient. 3. Using the new switching power supply, greatly reduce power consumption and increase the transmission distance of the instrument. 4. Increases the fault self-test function, easy to use and maintain. 5. Designed a new high-strength shell structure, enhanced impact resistance of the instrument. Fifth, the main parameters of a suitable condition Ambient temperature: 0 ℃ ~ 40 ℃; Relative humidity: ≤ 98% RH; Atmospheric pressure: 80kPa ~ 116kPa for containing gas or coal dust explosion hazards in the coal mine. 2, the main technical indicators: 2.1 Working conditions: Temperature: 0 ~ 40 ℃; Relative humidity: ≤ 98%; Atmospheric pressure: 86 ~ 116kPa Jining Branch-mining equipment, large favorably, please call
