1. To detect pressure sensors, apply pressure according to different purposes. The method for checking the double shear beam weighing sensor is to supply power to the sensor, blow the air guide hole of the pressure sensor with the mouth, and use the voltage range of the multimeter to detect the voltage change at the output terminal of the sensor. If the relative sensitivity of the pressure sensor is high, this change will be significant. If there is no change at all, it is necessary to use a pneumatic source to apply pressure.

2. The detection of bridge circuits mainly checks whether the circuit of the sensor is correct. Generally, it is a Wheatstone full bridge circuit, which uses the ohm range of a multimeter to measure the impedance between the input terminals and the impedance between the output terminals. These two impedances are the input and output impedances of the pressure sensor. If the impedance is infinite, the bridge circuit is disconnected, indicating that there is a problem with the sensor or the pin definition is not correctly determined.

3. Zero point detection, using the voltage range of the Celtron DLB double shear beam weighing sensor with a multimeter, to detect the zero point output of the sensor under the condition of no applied pressure. This output is usually a voltage in the mV range. If it exceeds the technical specifications of the sensor, it indicates that the zero point deviation of the sensor is out of range.
