Product description

How to test the quality of hydraulic high pressure sensor? Appearance check: If the fault information can be determined by appearance check, the device is damaged. Related electrical characteristics test to further determine the fault type, test output low voltage, no voltage output, for example, when the system pressure is normal, there is input voltage, no output voltage, equipment damage. Measure the correct output voltage under different pressures, and adjust the input DC voltage of the pressure sensor according to the drawing. When the pressure changes, check whether the multimeter displays a value (Generally, the output voltage of the high-voltage pressure sensor is about 0.9V, and that of the low-voltage pressure sensor is about 0.5V). If it is not displayed, it is damaged. When the refrigerant is normal, measure the saturation temperature corresponding to the static pressure according to the technical specifications to see whether it is consistent with the actual temperature. Specializing in the manufacture of waste fuel pressure sensor, oil pressure sensor, engineering hydraulic sensor, injection molding machine special pressure transmitter.
