Overview
HPM768 ceramic capacitive pressure transmitter uses imported ceramic sensor as a sensitive element,it directly detects the pressure signal by flush membrane. Ceramic has the characteristics of high elasticity, wear resistance, corrosion resistance, and fast heat dissipation, which makes the transmitter very good thermal stability and extremely low temperature drift. The minimum range of this product can reach 500Pa, and the anti-overload capability can reach dozens of times of the full range, which completely solves the problem of poor overload capability in small ranges and it is very suitable for micro-pressure measurement.
Since the ceramic sensor is free of any filling fluid, there is no process contamination, and its dry ceramic diaphragm is not affected by the installation orientation. The clamp end face of this product is exposed directly to detect the pressure, which can prevent scaling, unsanitary and viscous pressure blockage and other problems. It is widely used in food, medicine, winemaking and other hygienic industries and measures the pressure of media where scaling may occur.
