Power is connected to the positive terminal of the DC power supply, the iron is connected to the negative terminal of the DC power supply, the signal wire is connected to the signal input port of the device.
Foton Xiangling Differential Pressure Sensor Working Principle
The resistance strain gauge is one of the main components of the piezoresistive strain sensor.
Metallic resistance strain gauges work on the principle of adsorption on the substrate material strain resistance with mechanical deformation and the phenomenon of resistance change, commonly known as the resistance strain effect.
Ceramic Pressure Sensors
Ceramic pressure sensors are based on the piezoresistive effect, the pressure acts directly on the front surface of the ceramic diaphragm, causing the diaphragm to produce a small deformation, the thick film resistor is printed on the back side of the ceramic diaphragm, connecting it to form a Wheatstone bridge, and due to the piezoresistive effect of the piezoresistor, the bridge produces a highly linear, proportional to the pressure, and proportional to the excitation voltage. The standard signal is calibrated to 2.0/3.0/3.3mV/V and so on according to the different pressure ranges, which can be compatible with strain gauge sensors.
