Abstract
A pressure sensor air tightness tester comprises a pressure source, an electromagnetic valve, a high-accuracy pressure transmitter, a testing table, a to-be-tested pressure sensor and the like. The pressure sensor air tightness tester is characterized in that the electromagnetic valve is connected in series on the right side of the pressure source; the testing table is connected in series on the right side of the electromagnetic valve; the high-accuracy pressure transmitter is connected parallelly between the testing table and the electromagnetic valve; a spigot is arranged at one end of the testing table; and the to-be-tested pressure sensor is connected with the testing table through the spigot. When the pressure source is opened, the to-be-tested pressure sensor can convert the born pressure value into current signals which can be displayed inside the high-accuracy pressure transmitter. The pressure sensor air tightness tester has simple structure, low cost and capabilities of increasing working accuracy and sensitivity of the pressure sensor air tightness tester and being suitable for various pressure sensor manufactures to use in testing.
Description
Technical field
The utility model relates to the Test Equipment field of sensor, particularly a kind of pressure transducer air tightness test instrument.
Background technology
At present, its precision of the tester of known sensor and susceptibility are lower, especially the testing tool of pressure transducer is not very sensitive to the reaction of gas density and micro-air pressure, so that the staff when nuclear is read instrument institute response data with actual impermeability gap slightly, be fatal weakness in this industry for space flight or other high-precision requirement.
Summary of the invention
In order to overcome above-mentioned deficiency, the utility model provides a kind of pressure transducer air tightness test instrument, it is a series electrical magnet valve behind pressure source, high-precision pressure unit in parallel again behind solenoid valve then, like this after the testing pressure sensor is placed into monitor station, the pressure that this pressure transducer bore converts the magnitude of current to through the high-precision pressure transmitter and shows on instrument.
The utility model solves technical scheme that its technical matters adopts: a kind of pressure transducer air tightness test instrument, it comprises pressure source, solenoid valve, the high-precision pressure transmitter, monitor station and testing pressure sensor etc., it is characterized in that: described solenoid valve is series at the pressure source right side, be in series with monitor station again on the solenoid valve right side, described high-precision pressure transmitter is parallel in the middle of monitor station and the solenoid valve, described monitor station one end is provided with socket, the testing pressure sensor is connected with monitor station by this socket, after pressure source is opened, the testing pressure sensor can convert the force value of being born to current signal, shows in the high-precision pressure transmitter.
The beneficial effects of the utility model are: simple in structure, with low cost, the homework precision and the sensitivity that have improved pressure transducer air tightness test instrument are fit to each pressure transducer manufacturer and detect use.
