Embodiment Construction
[0017] see figure 1 . According to the present invention, in the performance test system of the externally excited vibrating cylinder pressure sensor, a vibrating cylinder pressure sensor is used as the standard pressure sensor, and the measured sensor as the measured part is connected between the standard pressure sensor and the standard amplifier, and the composition is composed of A test tool that is electrically connected to the test circuit of the susceptor under test; the two-body spring probe is used to contact and connect the coil pins on the susceptor to be tested, and a fixed base is used to move the two-body spring probe to electrically connect the test circuit and the test circuit. For the test piece, fix the sensor under test on the test fixture, and then apply the same working pressure to the sensor under test and the standard pressure sensor, starting from 0kPa, and gradually increase to the full scale at every 0.25kPa pressure, using signal conditioning The PX...
