Foreword
The standard was drafted in accordance with the rules given in GB/T 1.1-2009.
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/sensor
1 Scope
This 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).
