Multi-parameter water quality analyzer
The corrosion-resistant ceramic pressure sensor operates without liquid transmission, with pressure applied directly to the ceramic diaphragm, causing slight deformation. Thick-film resistors are printed on the back of the diaphragm to form a Wheatstone bridge. Due to the piezoresistive effect, the bridge generates a highly linear voltage signal proportional to both pressure and excitation voltage. Depending on the pressure range, the standard output signal is calibrated to 2.0 / 3.0 / 3.3 mV/V, compatible with strain gauge sensors.
With laser calibration, the sensor ensures excellent temperature and long-term stability, featuring built-in temperature compensation from 0–70°C. It is suitable for direct contact with a wide range of media.
