Piezoelectric ceramic pressure sensor and PCB board transmitter module
High stability ceramic capacitive pressure core high precision shock resistance pressure sensor 5~600bar
Product description
The sensors are piezoresistive pressure sensors based on ceramic. The measuring bridge is printed directly on one side of the ceramic diaphragm by means of thick film technology. The rear part of the diaphragm can be exposed directly to the medium to be measured. Because of the excellent chemical resistance no additional protection is normally required.
Thanks to the reinforced outer area (monolithic structure)the sensor can be mounted directly in a case by using an O-ring or else it can be mounted to a metal fitting. The sensors are designed in such a way so that temperature changes and overloading do not cause any loss in reliability. The use of ceramic ensures high linearity across the entire range of measurement and reduces effects of hysteresis to a minimum.

cent FS / year 7, common unit conversion relationship:
10 bar=1 MPa=106 PaMPa=100 mH 2Obar=145 psibar=10.2 kgf/cm²
VIII. Use considerations:
1. the core is installed, nylon washer should be installed on the lead surface of the core to make the core force uniform and avoid zero point instability. Before 2. the welding lead, please preheat the core body, increase the solderability of the solder joint, avoid the solder joint heating for a long time to reduce the adhesion of the pad. For welding, use no more than 60 W of tip soldering iron. 3. the black film part do not touch, scratch the black film will damage the internal circuit, damage the sensor
