Description
Technical field
The utility model relates to detection device more particularly to a kind of high static pressure differential pressure transmitter detection devices.
Background technique
Differential pressure transmitter is widely used in the measurement of flow and liquid level, now to differential pressure transmitter verification be mostly into
The high static pressure differential pressure transmitter of mouth is verified manually, generates static pressure signal and differential pressure letter by manually adjusting using high pressure gas cylinder
Number, defencive function can not be set, measure differential pressure signal, nothing by two static pressure signal arithmetical differences using two static pressure transducers
Method carries out high-acruracy survey to differential pressure signal, and verification process is cumbersome, to the more demanding of testing person, and because gas cylinder compared with
Greatly, not easily shifted, scene use can not be arrived.
Summary of the invention
The utility model is to solve the above problems, provide a kind of inspection of simple high static pressure differential pressure transmitter of verification process
Survey device.
Technical solution adopted in the utility model:
A kind of high static pressure differential pressure transmitter detection device, including it is detection device ontology, stepper motor, vacuum pump, piston, quiet
