Description
Technical field
The utility model belongs to the mining equipment technical field, relates to a kind of sensor, especially a kind of mining differential pressure pick-up
Background technology
China is big coal country, output of coal leaps to world front three, because most of coal all is stored in the underground, so must exploit with the form of mine, and underground work is breakneck for coal workman's personal safety, a lot of coal mining accidents all can occur every year in China, and all can pay each time the cost of blood.Therefore, the Environmental Monitoring under the mine just becomes particularly important.Circumstance complication under the mine, down-hole pressure also often change, and therefore, the monitor well downforce that needs a kind of reliable equipment to implement changes, and is convenient to the early detection Coal Mine Disasters, trouble-saving generation.
The utility model content
The purpose of this utility model is to overcome the shortcoming of above-mentioned prior art, a kind of mining differential pressure pick-up is provided, this sensor can show the differential pressure value of measured point in real time, the output of band digital interface can be used with domestic other mine supervision system, Digital Mine system and life saving system are compatible.
