Ceramic pressure sensor working principle

The corrosion-resistant ceramic pressure transmitter has no liquid transfer. Pressure acts directly on the front surface of the ceramic diaphragm. Make the membrane slightly deformed. Thick film resistors are printed on the back of the ceramic diaphragm and connected to form a closed Wheatstone bridge.

Due to the piezoresistive effect of the varistor, the bridge generates a voltage signal that is highly linear and proportional to the pressure and proportional to the excitation voltage. The standard signal is calibrated to 2.0 / 3.0 / 3.3 mV / V according to the different pressure ranges, which is compatible with strain gauge transmitters.

Through laser calibration, the transmitter has high temperature stability and time stability. The transmitter comes with temperature compensation of 0 ~ 70 ℃, and can directly contact most media.

Ceramic is a recognized material with high elasticity, corrosion resistance, wear resistance, shock resistance and vibration. The thermal stability of ceramics and its thick film resistance can make its operating temperature range as high as -40 to 135 ° C, and it has high accuracy and stability for measurement. The degree of electrical insulation is> 2kV, the output signal is strong, and the long-term stability is good.

Ceramic Diaphragm Pressure Sensor

The ceramic Diaphragm pressure sensor is a ceramic piezoresistive pressure sensor refined by a thick ceramic process using a refined ceramic base. Overall dimension Φ18mm * 6.35mm. Ceramic is a recognized material with high elasticity, corrosion resistance, wear resistance, impact resistance and vibration.

The good thermal stability of the ceramic and the high-temperature sintering process of the thick film make the working temperature range of the ceramic pressure sensor up to -40 ~ 125 ℃. The ceramic’s high elasticity and creep resistance make the ceramic pressure sensor have good long-term stability. In addition, the corrosion resistance of ceramics makes it uniquely advantageous in the fields of refrigeration, chemicals and environmental protection.

Piezoresistive Pressure Sensor

 Piezoresistive pressure sensor

The piezoresistive pressure sensor is constructed using the piezoresistive effect of single crystal silicon. A single crystal silicon wafer is used as an elastic element, and an integrated circuit process is used on the single crystal silicon membrane. A group of equivalent resistors are diffused in a specific direction of the single crystal silicon, and the resistors are connected into a bridge circuit. The single crystal silicon wafer is placed on Sensor cavity. When the pressure changes, the single crystal silicon produces strain, so that the strain resistance directly diffused thereon changes proportional to the measured pressure. Then the bridge circuit obtains the corresponding voltage output signal.
