On --spot calibrating device of surge pressure sensor

The utility model relates to an on - -spot calibrating device of surge pressure sensor, produce device, standard sensor and be used for being gathered the data process system of processing by calibration surge pressure sensor with the data of standard sensor including surge pressure, surge pressure produce the device include the propellant supply system, with the propellant supply line of propellant supply system exit linkage, set up the propellant valve on propellant supply line, the flow regulator who is used for adjusting the pressure adjustment assembly of propellant supply line internal pressure and is used for adjusting the propellant flow, be used for measuring the pressure in the propellant supply line on calibration surge pressure sensor and the propellant supply line of standard sensor settings behind the propellant valve. The utility model discloses an establish surge pressure and produce the device, true water hammer sensor operational environment during analogue test, elimination system error has improved surge pressure measuring accuracy.
