Industry Information
Ceramic sensor will be the development of pressure transmitter
2012-2-28 10:04:58

其传感器采用干式陶瓷压力传感技术,具有精度高、长期稳定性好、工作温度范围宽、抗载能力强、体积小,膜片面积大、不积物、可带现场指示器和不带现场指示器。 DEC-DBS301 flanged ceramic liquid level transmitter uses dry ceramic pressure sensor technology, with high accuracy, long-term stability, wide operating temperature range, strong load resistance, small volume, large diaphragm area , Without accumulation, with and without field indicator. Its process connection form is standard flange, flange material 1CrNi9Ti and polytetrafluoroethylene. DEC-DBS301 flange type ceramic liquid level transmitter has been widely used in various fields for the static pressure and liquid level measurement of corrosive media liquids, especially the pressure, liquid level measurement in the sanitary, food and viscous media industries. It can also be used to measure pressure parameters such as gas or steam.
● Main technical indicators Measurement range Relative pressure: 0 ~ 1.6MPa, -0.1 ~ 1.6MPa Minimum measurable ± 1KPa (100mmH20)
Static liquid level maximum liquid level height: 100m minimum liquid level height: 0.1m
Measuring diaphragm 96% alumina ceramic flange 1Cr18Ni9Ti polytetrafluoroethylene seal fluoro rubber fluorosilicone rubber

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-cost ceramic sensors will be the development direction of pressure transmitters.

厚膜电阻印刷在陶瓷膜片的背面,连接成一个惠斯通电桥(闭桥),由于压敏电阻的压阻效应,使电桥产生一个与压力成正比的高度线性、与激励电压也成正比的电压信号,标准的信号根据压力量程的不同标定为2.0 / 3.0 / 3.3 mV/V等,可以和应变式传感器相兼容。 Principle The anti-corrosive pressure transmitter has no liquid transmission. The pressure directly acts on the front surface of the ceramic diaphragm, causing the diaphragm to deform slightly. The flange-type ceramic level transmitter thick film resistor is printed on the ceramic diaphragm. On the back side, it is connected to a Wheatstone bridge (closed bridge). Due to the piezoresistive effect of the varistor, the bridge generates a voltage signal that is highly linear and proportional to the excitation voltage. The standard signal is based on Different calibration of pressure range is 2.0 / 3.0 / 3.3 mV / V, etc., which can be compatible with strain gauge 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.

main feature

The transmitter is a variant of the DBS series. Available with and without field indicator. There are two types of process connection: G1 1/2 and G2 external threads.
The transmitter has high accuracy, long-term stability, wide working temperature range, strong resistance to overload, small size, flush diaphragm structure, no accumulation, no blockage, easy cleaning and convenient installation. It is widely used in various industries to measure the pressure of viscous liquids, gases, and steam, and is especially suitable for pressure measurement in the pharmaceutical, health, and food industries.
