The water level transducer is a pressure transducer to measure water level. The static pressure input type liquid level transmitter (level gauge) is based on the principle that the measured liquid static pressure is proportional to the height of the liquid. It adopts foreign advanced isolated diffused silicon sensitive elements or ceramic capacitor pressure sensitive sensors, converting the static pressure into an electric signal, and then converting the electric signal into a standard electric signal (generally 4-20mA/1-5VDC) after temperature compensation and linear correction.
One type is contact-type transmitter, including single-flange static pressure/double-flange differential pressure level transmitter, float-type level transmitter, magnetic level transmitter, drop-in level transmitter, electric internal floating ball level transmitter, electric float level transmitter, capacitive level transmitter, magnetostrictive level transmitter, servo level transmitter, etc.
The second category is non-contact type, which is divided into ultrasonic level transmitter, radar level transmitter and so on.
Among all the pressure transducer to measure water level, The hydrostatic input level transmitter (level gauge) is suitable for level measurement of various media in petrochemical, metallurgy, electric power, pharmaceutical, water supply and drainage, environmental protection and other systems and industries. The exquisite structure, simple adjustment and flexible installation provide convenience for users to use easily. Standard signal output modes such as 4-20mA, 0-5v, 0-10mA can be selected by users according to their needs.
Using the principle of hydrostatics to measure liquid level is an important application of pressure sensors. And it is specially made for the strong corrosive acidic liquid in the chemical industry. The shell is made of polytetrafluoroethylene material. It uses special fluorine rubber cable and special sealing technology for electrical connection, which not only ensures the water tightness and corrosion resistance of the sensor, but also makes the reference pressure chamber communicate with the ambient pressure, thus ensuring the high accuracy and stability of the measurement.
