Mine differential pressure sensor GPD10 Main features: First, use GPD10 differential pressure sensor (hereinafter referred to as the sensor) is to meet our need for coal mine monitoring downhole pressure and developed. It can continuously and automatically be converted into a standard electrical downhole pressure transmission to the mating device. Sensor proof test by the state authorities for online examination, can be used with various types of monitoring system supporting domestic use. Second, the model implications, explosion-proof type and mark G ----- Product Type Code: sensors. P ----- first feature code, the pressure; D ----- second feature code, electronic; 10 ----- main parameters Measuring range: (0 ~ 10KPa); sensor type of protection for the Mine 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: Working conditions: Temperature: 0 ~ 40 ℃; Relative humidity: ≤ 98%; Atmospheric pressure: 86 ~ 116kPa 2.2 range and basic error: the basic error of measurement parameters pressure measuring range 0? 10KPa ≤ ± 2% (FS) 2.3 Resolution: KPa 2.4 Display: Four LED 2.5 Response Time: 30s 2.6 Working method: semiconductor-type 2.7-proof type: Mine intrinsically safe ExibI Mb Output signal: Frequency: 200? 1000Hz; Jining City Branch-mining equipment, large favorably, please call
