The pressure sensor working life test bench is a special test equipment, which is designed for internal flow tests such as thermostats, sensors, valves, and inductors. The test bench can simulate the dynamic and static pressure of the pressure sensor under actual working conditions, and carry out reliability tests such as pressure calibration and pressure impact test on the sensor. Through these tests, we can understand how the pressure sensor behaves under different pressures and changes in the external ambient temperature. The test bench is suitable for a variety of assemblies with similar working conditions, such as pressure sensors. The parameters are as follows: the differential pressure range is 0 5MPa and 5 10MPa, and the control accuracy is 10MPa accuracy 03%FS, 5MPa accuracy 01%FS, the fluctuation is 1kPa and 6kPa, and the holding time can be set on the computer, and the range is 0 9999 seconds. The control mode can choose PID closed-loop control or manual control, which is easy to switch.
In terms of specimen monitoring, the power supply is DC5V, the power supply accuracy is 5mV, the monitoring channel has 1 20 channels to select, and the channel independence can be monitored individually or as a whole. In addition, the deviation can be adjusted to a% or v, which can be set by computer, has a waveform display function, can output channel data in real time, and the monitoring time is up to 0 99999 hours.
The test bench is characterized by the automatic recording of temperature, pressure and corresponding output data, which is convenient for export analysis. The software automatically adjusts the oil pressure, the pressure and frequency of the test bench can be adjusted, and it has the functions of counting and reminding faults. In addition, the test bench is also compatible with product experiments with different pressure ranges, making the test more flexible and diverse.
