Product description

Type and working principle of Water Pressure Sensor: Piezoresistive Pressure Sensor. Resistance strain gauge is one of the main components of piezoresistive strain sensor. The working principle of metal strain gauge is that the strain resistance adsorbed on the substrate changes with mechanical deformation, commonly known as resistance strain effect. Ceramic Pressure Sensor. Ceramic pressure sensors are based on piezoresistive effects. The pressure acts directly on the front of the ceramic diaphragm, causing the diaphragm to deform slightly. Thick film resistors are printed on the back of the ceramic diaphragm and connected to form a Wheatstone bridge. Due to the piezoresistive effect of the varistor, the bridge produces a highly linear voltage signal proportional to the pressure and excitation voltage. The standard signal can be calibrated to 2.0/3.0/3.3MV/V according to different pressure ranges and can be used with strain sensors. Diffused silicon pressure sensor. The working principle of the diffused silicon pressure sensor is also based on piezoresistive effect. Using the piezoresistive effect principle, the pressure of the measured medium directly acts on the diaphragm of the sensor (stainless steel or ceramic), so that the diaphragm produces a micro displacement proportional to the pressure of the medium, and changes the resistance value of the sensor. Electronic circuits are used to detect this change, converting and outputting a standard measurement signal corresponding to the pressure.
