As shown in Figures 1 to 4, a kind of pressure sensor detecting device, including shell 1,1 top coverboard of shell are equipped with pressure
Force snesor 2, pressure sensor 2 are connect with integrated mainboard 3, and integrated mainboard 3 and power supply 8, integrated mainboard 3 and power supply 8 are set to
The inside of shell 1, integrated mainboard 3 are also electrically connected with display lamp and alarm speaker 5, and display lamp and alarm speaker 5 are distinguished
On the side coverboard of shell 1, assembling assembly 6 is additionally provided on the rear coverboard of shell 1；The utility model passes through pressure sensor
2 detections, detection data is directly entered output signal after integrated mainboard is handled, analyzed and compare, then starting display lamp or
Person's alarm speaker issues early warning.The present apparatus can be with independent detection pressure, and carries out data analysis, sounds an alarm.It shortens
The sensitivity of sensor is improved indirectly reaction time, can timely issued warning signal, it is possible to prevente effectively under mine
Safety accident.
In order to further determine signal, display lamp includes red colored lamp 4a and green light 4b, red colored lamp 4a and alarm speaker 5
It is connect by same circuit with integrated mainboard 3, green light 4b is connect by another circuit with integrated mainboard 3.When integrated mainboard 3 is right
When score Precipitating pressure value exceeds preset value, warning circuit starting, red colored lamp is lighted to be issued warning signal with alarm speaker, when
3 comparative analysis of integrated mainboard goes out pressure value in preset range, and warning circuit is not turned on, and connects the power on circuitry of green light, green
Colored lights lights.This state issues two signals to miner, first is that pressure sensor is working normally, second is that pressure value is safety
Value.Pressure signal is shown by display lamp simultaneously, is conducive to people and recognizes whether pressure value is peace in dark conditions
Total head.
It is set on the upper plate of shell there are three resistance strain type sensor, the foil gauge of resistance strain type sensor is foil
