Static liquid level industrial grade universal piezoresistive liquid level sensor is to constitute gauge pressure sensitive element into the stainless steel shell with high reliability and high accuracy. The end part of the casing steel cap protects the pressure sensitive sensing element of film role, also can make the fluid smoothly to touch pressure diaphragm, protection of cables and shell sealing connection, cable guide pipe, the sensor cable at the outlet of the back pressure chamber and the atmosphere, to ensure the accuracy of measurement. The accurate conversion of pressure to electrical signal is realized. Measuring range from 0 - 2 m to 0 - 200 m. Characteristics and application: input - mounted, strong overload capacity - stability, full-scale - year long life is better than 0.1%, can be used for continuous monitoring of the level of strong anti-interference ability, high accuracy and repeatability can reach 0.1, 0.25, 0.5 - 4-20mA analog HART communication protocol and high protection level of output / with liquid level monitoring - up to IP68 - suitable for large tank is suitable for deep water measurement, can be used to measure the liquid tank, tank, pit, and corrosive liquids. - mainly used in water treatment and water measurement, shipbuilding, petroleum, chemical, power equipment, electronics, food - chemical, dyeing and finishing rubber and plastic, hydraulic machinery, chemical and pharmaceutical industries.
