Features
1. Pure ceramics basically do not produce process pollution, and are suitable for food and pharmaceutical industries.
2. Small size, more suitable for supporting various mechanical equipment.
3. Special anti-corrosion ability.
4. It is less affected by temperature and not affected by the installation direction.
Principle of imported ceramic pressure sensor
The corrosion-resistant ceramic pressure sensor has no liquid transmission. The pressure directly acts on the front surface of the ceramic diaphragm, causing a slight deformation of the diaphragm. The thick film resistor is printed on the back of the ceramic diaphragm and connected to form a Wheatstone bridge (closed). Bridge), due to the piezoresistive effect of the varistor, the bridge generates a highly linear voltage signal proportional to the pressure and proportional to the excitation voltage. The standard signal is calibrated to 2.0/3.0/3.3 according to the pressure range. mV/V, etc., compatible with strain gauge sensors. Through laser calibration, the sensor has high temperature stability and time stability. The sensor comes with a temperature compensation of 0～70℃, and it can be in direct contact with most media.
