Detailed Description

GPD80G Pressure sensor GPD80G Pressure sensor (hereinafter referred to as sensor) is composed of single-chip microcomputer and integrated pressure sensor component pipe pressure sensor. Intelligent sensor design, innovative technology, the function is all ready. Sensor to the gas pressure in the coal mine gas drainage pipeline continuous testing, and will detect the pressure value converted to the corresponding frequency signal is sent to a device context. Suitable for coal mine gas drainage pipeline gas pressure of the real-time continuous full range automatic detection. The main technical parameters and performance Working conditions: The environment temperature (0 ~ 40 ℃); Relative humidity: 98% RH or less; The atmospheric pressure (100 ~ 110) kPa; With methane and coal dust, used for the dangerous sites with explosive mixture; Storage temperature: (20 ~ 55 ℃); The rated working voltage: DC18V; The rated working current: 100 ma or less; Sensor in general should be able to in the input voltage (12 ~ 24 V) within the scope of work; The Ann parameters: Ui: DC 18 v.
