Product description

Pressure Sensor test good or bad? Bridge detection, the main detection sensor circuit is correct, generally Wheatstone full bridge circuit, the ohm of the multimeter, the impedance between the input end, and the impedance between the output end, the two impedance is the input and output impedance of the pressure sensor. If the impedance is infinite, the bridge is broken, indicating a problem with the sensor or an incorrectly defined pin. Zero detection, using a multimeter voltage to detect the zero output of the sensor under no pressure. The output voltage is usually mV level. If it exceeds the technical index of the sensor, it indicates that the zero deviation of the sensor is out of range. Pressure detection, check method is: to supply power to the sensor, blow the pressure sensor pilot hole with the mouth, use the multimeter voltage file to detect the change of the sensor output voltage, if the relative sensitivity of the pressure sensor is very large, the change will be obvious. If nothing changes, you need to switch to the stressor. Specializing in the manufacture of Urea Pressure Sensor, common rail Pressure Transmitter, engineering hydraulic sensor, injection molding machine special pressure sensor, water purifier pressure transmitter, etc.
