This standard replaces GB/T 15478-1995 “Test methods of the performance for pressure transducer/sensor”. As compared with GB/T 15478-1995, the main changes of this standard are as follows. -In 3.1.2 and 3.1.3, MODIFY the relative humidity to “30% ~ 85%”, and MODIFY the deviation range to “± 5%”; -CANCEL the clause 3.2 dynamic conditions from the original standard; - Respectively determine the indicators in 3.3.1b), 3.3.2 and 3.3.3 as 1/3, 1/5 and 1/5; -In 5.3.2b), with respect to the output impedance, DIVIDE the sensor circuit into passive circuit and active circuit, with corresponding test methods; -In 5.4.2.4, MODIFY the hysteresis definition to “Hysteresis is, at the same test point, the maximum absolute value of the output difference when the measured value increases and decreases”; -In 5.4.2.5, MODIFY the repeatability definition to “Repeatability is the consistency between successive measurement results”; -REMOVE the two indicators “zero drift” and “overload (overload)”from the static performance indicators, both of which are listed as independent items; - CHANGE the “sensitivity stability” to “full scale output stability”; -In 5.6.2b), MODIFY the “... 5 to 10 times the dynamic performance of the sensor.” to “... 5 times the dynamic performance of the sensor.”; -In 5.9.2.1,CONDUCT detailed descriptions against the “temperature effect test”, making specific requirements; MODIFY the “thermal sensitivity drift” to “thermal full-scale output drift”; MODIFY the “thermal sensitivity lagging” to the “thermal full scale output lagging”; MODIFY the “conduct three measurement upper and lower calibration cycles” to the “conduct one measurement upper and lower calibration cycle (only one cycle is measured)”; Test methods of the performances for pressure transducer/sensor1 ScopeThis standard specifies the test conditions, the general provisions of the test, the test items and the test methods, AND data calculation and processing for the performance of the pressure sensor (abbreviated as sensor). This standard applies to pressure sensors (including absolute pressure sensor, differential pressure sensor, gauge pressure sensor AND negative pressure sensor).2 Normative referencesThe following documents are essential to the application of this document.
