Product description

Common pressure sensors are: 1, strain type Pressure Sensor. Strain type pressure sensor A sensor that measures pressure mainly by measuring the strain of an elastic element. According to the different materials, the strain elements can be divided into metal and semiconductor. When conductors and semiconductor materials undergo mechanical deformation, their resistance values will change. 2, Piezoresistive Pressure Sensor. Piezoresistive pressure sensor is made of piezoresistive effect of monocrystalline silicon material and integrated circuit. When a monocrystalline silicon material is subjected to a force, its resistivity will change. At this time, an electrical signal proportional to the force change will be output through the measuring circuit. Different from the stick-on strain gauge, the pressure measured is felt mainly through the silicon diaphragm. 3, capacitive pressure sensor. Capacitive pressure sensor mainly adopts capacitance, which converts the measured pressure into a pressure sensor with capacitance change. The electrode of the capacitor is round metal film or gold-plated film. When the film feels the pressure and deforms, the capacitance changes and the electrical signal is formed. 4. Piezoelectric Pressure Sensor. Piezoelectric pressure sensor adopts piezoelectric effect, using electrical components and other machinery to convert pressure into electricity, and then the relevant measurement of the instrument. Specializing in the manufacture of high precision pressure sensor, Diesel Pressure Sensor, Refrigerant Pressure Sensor, injection molding machine Pressure Transmitter.
