Abstract
The utility model is related to a kind of pressure sensor checking tools.It is made of components such as vessel, meter connector, sealing ring, verification pressure gauge, sensor connector, vent valve and manual air charging systems.By connecting the parts such as manual air charging system, meter connector, sensor connector and vent valve around gas chamber holding, then it is connected with the verification pressure gauge of different accuracy and scope, can realizes the verification to pressure sensor in wide scope.The checking tool is easily manufactured, at low cost, and has many advantages, such as that verification scope is wide and precision is high.
Description
Technical field
The utility model is related to the verification of mining pressure sensor, special mining electronic formula pressure sensor.
Background technology
Before seam mining, carry out first taking out the scheme adopted afterwards, to take out fixed output quota.In order to effectively determine gas extraction
For amount, it is necessary to be measured to the gas of extraction, the characteristic quantity of metering is mainly pressure, flow and concentration.Due to the pressure in pipeline
Power detection is changeable, by the way of pressure gauge, since pressure gauge low-response is difficult accurately to measure.It is sensed using electronic pressure
Device since electronic type response is fast, and is easy to upload data, is primary selection, also allows for realizing online measurement.
But how electronic pressure sensor effectively realizes how are periodic detection in company and the precision reached, mesh
Before lack suitable metering method.The present invention is solves the problems, such as that this devises a kind of checking tool.
The content of the invention
The utility model provides a kind of pressure and passes to exist when solving the problems, such as existing mining pressure sensor verification
Sensor checking tool, wide scope accurately realize verification to pressure sensor.
The technical solution of the utility model is a kind of pressure sensor checking tool, by being accessed in the outside for holding gas chamber
The parts such as meter connector, verification pressure gauge, sensor connector, vent valve and manual air charging system, realize to pressure sensor
Verification.
The beneficial effects of the invention are as follows：By design verification frock, realize the metering to company's pressure sensor and
Calibration reduces metering and verification expense.
Description of the drawings
Accompanying drawing 1 is the structural representation of the present invention.
In figure：1 holds gas chamber, and 2 meter connectors, 3 sealing rings, 4 verification pressure gauges, 5 sensor connectors, 6 vent valves, 7 fill manually
Device of air.
Specific embodiment
As shown in Figure 1, a kind of pressure sensor checking tool, by appearance gas chamber 1, meter connector 2, sealing ring 3, verification pressure gauge
4th, the components such as sensor connector 5, vent valve 6 and manual air charging system 7 form.Gas chamber 1 is held to be welded by steel plate air-tightness first and
Into；Then, welding meter connector 2 above gas chamber 1 is being held；Sensor connector 5 is welded on the right side for holding gas chamber；Holding gas chamber
Front is welded with vent valve 6；Manual air charging system 7 is welded on the left side for holding gas chamber；Verify pressure gauge 4 by sealing ring 3 with
Meter connector 2 is connected.
In use, the pressure sensor for needing to verify is connected with sensor connector, then inflation manually, can compare school
The error of pressure gauge and pressure sensor is tested, completes the metering to pressure sensor.
Technology that the utility model is not described in detail, shape, construction part are known technology.
