Operating Principle:
Corrosion-resistant ceramic pressure sensors feature no fluid transfer; pressure acts directly on the front surface of the ceramic diaphragm, causing minute deformation. Thick-film resistors are printed on the back of the ceramic diaphragm, forming a Wheatstone bridge (closed bridge). Due to the piezoresistive effect of the pressure-sensitive resistor, the bridge generates a voltage signal that is highly linear with pressure and proportional to the excitation voltage. Standard signals are calibrated at 2.0 / 3.0 / 3.3 mV/V depending on the pressure range and are compatible with strain gauge sensors. Laser calibration ensures high temperature and time stability. The sensor includes temperature compensation from 0 to 70°C and can be directly contacted by most media.
Basic Features:
Ceramics are a high elasticity, corrosion-resistant, wear-resistant, shock and vibration-resistant material. Their thermal stability and thick-film resistivity allow operation at temperatures ranging from -40 to 135°C, with high precision and stability in measurements. Electrical insulation is greater than 2kV, with strong output signals and excellent long-term stability. High-performance ceramics at low prices will be the direction of pressure sensor development, with a trend of completely replacing other types of sensors in Western and European countries. In China, an increasing number of users are opting for ceramic sensors over diffused silicon pressure sensors.
