Detection apparatus for diaphragm type gas table equivalent gyration volume

The utility model discloses a detection apparatus for diaphragm type gas table equivalent gyration volume, including air inlet, diaphragm type gas literary name wheel counter, diaphragm type gas table counter least count dish cursor, photoelectric sensor, diaphragm type gas table gas outlet, the device still includes hall element, data acquisition module and magnetic element, magnetic element set up on the pendulum rod or bent axle by in being examined the table, hall element pastes and is being examined the lateral surface of table, just with magnetic element on same horizontal plane, hall element's signal output part mouth is connected to the port with data acquisition module's signal reception. Compare with present diaphragm type gas table detection device, this device can conveniently obtain to be examined the equivalent gyration volume of table, has good effect to shortening the diaphragm type gas table minimum flow point examination time greatly, shows the demand that intrinsic error examined and determine fast to the diaphragm type gas in having satisfied the mass production of enterprise.
