Abstract
The utility model relates to a diaphragm type mine sump water level monitoring sensor. The sensor fixes four resistance foil gauges on a circular diaphragm based on a certain manner; when the water level in a mine sump changes, the water pressure in the sump makes the circular diaphragm deform, and the internal resistance of the four resistance foil gauges fixed on the circular diaphragm correspondingly changes; and the real-time monitoring of the water level in the mine sump is realized by monitoring the variation of the output voltage of the full-bridge circuit formed by the four resistance foil gauges.
Description
Technical field
The utility model relates to a kind of diaphragm type pressure sensor, more specifically says the diaphragm type pressure sensor of the monitoring mine water bunker level that a kind of energy is real-time.
Background technology
Mine sump plays a part the industrial waste water that interim storage produces, the monitoring of mine sump water level is to prevent from flooding well and flooding the key factor that the pump accident occurs, can not scent a hidden danger timely by artificial inspection in the past, and bring to the safety in production of mine and have a strong impact on.
Summary of the invention
The purpose of this utility model is for the real-time monitoring mine water bunker level situation of energy, and has designed a kind of diaphragm type pressure sensor, can carry out Real-Time Monitoring to water bunker level intuitively, the generation of avoiding flooding well He flooding the pump accident.
The purpose of this utility model can realize in the following manner: can respond to the diaphragm type pressure sensor of sump variation in water pressure, include circular film and four identical resistance strain gages; Be characterized in that four resistance strain gages are fixed on diaphragm by certain way, one of them is fixed on the diaphragm center, and one is fixed on the diaphragm edge place, remaining two positions that are fixed on half length of diaphragm radius; When in sump, hydraulic pressure makes circular film deform, be fixed on four resistance strain gages on circular film thereupon deform in same pace and internal resistance changes, adopt the full-bridge circuit principle in Wheatstone bridge circuit to come the internal resistance of monitor strain sheet to change the variation of the input voltage brought.
The utility model compared with prior art has the following advantages: simple in structure, easy to use, in mine sump, the variation of hydraulic pressure can realize Real-Time Monitoring by the variation of output voltage.
The accompanying drawing explanation
Accompanying drawing 1 is the utility model structural representation.
In figure: 1, circular film, 2, resistance strain gage.
Embodiment
As follows with reference to accompanying drawing 1: as to monitor the diaphragm type pressure sensor of water bunker level, include circular film 1, be characterized in being fixed with four identical resistance strain gages 2 by certain way on circular film 1.
When the mine sump water level changes, the variation of water level causes that the hydraulic pressure in sump synchronously changes, hydraulic pressure makes circular film 1 deform, by certain way be fixed on four resistance strain gages 2 on circular film 1 thereupon resistance change, the variation of the output voltage by monitoring the full-bridge circuit that four resistance strain gages 2 form, just can realize the Real-Time Monitoring to water bunker level, and the utility model is simple in structure, with low cost, be easy to manufacture.
Claims (2)
