Another road low-pressure gas source wherein, through a three linked piece, low-pressure gas filters out IMPURITIES IN and moisture through three linked piece, and low-pressure gas source is directly given by test specimen through pipeline through the low-pressure gas valve;
When doing the test of high-pressure sensor, close low pressure gas circuit valve, open the high-pressure gas circuit valve, regulate pressure governor suitable high-pressure air source is given by test specimen by the road, the high-pressure sensor is carried out the performance and the endurancing of pressure transducer;
When doing the low-pressure sensor test, close the high tension loop valve, open low pressure gas circuit valve, low-pressure gas source is directly given by test specimen through pipeline through the low-pressure gas valve, low-pressure sensor is carried out the performance and the endurancing of pressure transducer.
Described three linked piece is a pneumatic triple piece, and this three linked piece comprises air strainer, reduction valve and oil sprayer, and is linked in sequence.
Beneficial effect; Owing to adopted such scheme; Under the low pressure source environment, can realize the high-low pressure pressure transducer is tested; The low-pressure gas source that will be used to test is introduced a three linked piece through pipeline, behind this three linked piece filtration impurity and moisture wherein, sends into a high-pressure booster through pipeline and carries out supercharging.Supercharging what select suitable supercharge pump and regulator according to test demand oneself; Realize in the method for high-low pressure pressure transducer test under above-mentioned according to low pressure source environment provided by the invention; Said with the high-pressure air source after the supercharging after regulator adjustment is suitable, send into testing table through the pipeline of a series connection three linked piece again, when needs test high-pressure sensor; Close low pressure line; Open pressure duct, regulate corresponding experimental pressure, can carry out the testing experiment of high-pressure sensor according to test procedure; Realize in the method for high-low pressure pressure transducer test under above-mentioned according to low pressure source environment provided by the invention; Said with one tunnel low-pressure gas source directly through one the series connection one three linked piece pipeline send into testing table; When needs test low pressure sensor, close high-pressure gas circuit, open the low pressure gas circuit; Regulate line pressure, can carry out the testing experiment of low-pressure sensor according to test procedure; Not limited to by the low pressure source, reached the object of the invention.
Advantage: 1, when the test low-pressure sensor, still adopt traditional testing table.Just want cutoff high part gas circuit then can, convenient and simple.
2, when needs test high-pressure sensor, only need low-pressure gas source is inserted supercharging part loop, close the low pressure gas circuit after the pressurized treatment and can realize test experiments the high-pressure sensor.Simple and easy to do.
3, the simple change of needs can realize the expansion significantly of pressure transducer test specification, change little, with low cost.For the test unit that does not have suitable source of the gas reduce investment outlay cost with a test method easily is provided.
