是DBS系列产品中的变形产品。 Ceramic pressure transmitter is a deformed product in the DBS series. Available with and without field indicator. There are two types of process connection: G1 1/2 and G2 external threads. The screw-in ceramic pressure transmitter has high accuracy, good long-term stability, wide operating temperature range, strong overload resistance, small size, flush diaphragm structure, no accumulation, no clogging, easy cleaning, and easy installation. Screw-in ceramic pressure transmitters are widely used in various industries to measure pressures of viscous liquids, gases, and steam, and are particularly suitable for pressure measurement in the pharmaceutical, health, and food industries. The anti-corrosive ceramic pressure sensor has no liquid transmission. The pressure directly acts on the front surface of the ceramic diaphragm, causing the membrane to deform slightly. The thick film resistor is printed on the back of the ceramic diaphragm and connected to a Wheatstone bridge (closed). Bridge), due to the piezoresistive effect of the varistor, the bridge generates a highly linear voltage signal proportional to the pressure and proportional to the excitation voltage. The standard signal is calibrated to 2.0 / 3.0 / 3.3 according to the pressure range mV / V, etc., compatible with strain gage sensors. Through laser calibration, the sensor has high temperature stability and time stability. The sensor has a 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. High-performance, low-price ceramic sensors will be the development direction of pressure sensors. There is a trend to replace other types of sensors in Europe and the United States. More and more users in China use ceramic sensors to replace diffused silicon pressure sensors.
