Description
Technical field
The utility model is related to sensor technical fields, particularly a kind of fixture of differential pressure pick-up caliberating device.
Background technology
Differential pressure pick-up is a kind of sensor for being used for measuring difference between two pressure, is surveyed in micro-flow measurement, leakage
Many high-acruracy survey occasions such as examination, clean room monitoring, environmental sealing inspection, gas flow measurement suffer from extensive use.
Two chambers are usually divided by flexible sheet inside common differential pressure pick-up, when the fluid into two chambers has pressure differential
When, it will cause the deformation of flexible sheet, and then the signals such as light, electricity is caused to change, divided by the signal to variation
Analysis obtains pressure differential information.Sometimes need to obtain the pressure differential information in special working environment, therefore, detection differential pressure sensing
Working performance of the device under high-low temperature difference pressure condition is necessary.
Utility model content
It is above-mentioned in order to solve the problems, such as, the utility model discloses a kind of fixture of differential pressure pick-up caliberating device,
It is described comprising power outlet, stent, closed pressure head, cylinder, guide post, guide sleeve, guide post fulcrum bearing, positioning plate, bottom plate and fixed seat
Stent is connected with bottom plate, is connected on the outside of the upper end of stent with cylinder, inboard to be connected with closed pressure head, and gas is connected on closed pressure head
Source, the guide post fulcrum bearing are mounted on bottom plate, and a through hole is machined in guide post fulcrum bearing, and the guide post passes through guide post fulcrum bearing
On through hole be mounted on guide sleeve in, the positioning plate be mounted on guide sleeve upper end, the fixed seat be mounted on positioning plate on, it is described
Power outlet is mounted on the rear end of positioning plate and fixed seat.
Further, processed on the positioning plate it is fluted, for mounting-fixing base.
Further, the lower end of the power outlet, the upper end of bottom plate are provided with socket fixing board.
Further, anticollision bullet glue is provided in the power outlet.
Further, the guide post fulcrum bearing number at least two.
Further, the fixed seat is bakelite bullet pin fixed seat.
The utility model is simple in structure, and manpower consumption is few, can improve the detection efficiency of differential pressure pick-up, eliminates because differential pressure passes
Monitoring data are inaccurate caused by the working performance of sensor is unstable, and practicability is wide.
