overview：

LT10SR-2700 intelligent liquid level transmitter that has full stainless steel structure is a fully sealed submersible liquid level measuring instrument, it adopts high-stability and high-reliability OEM pressure sensor and high-precision processing circuit. Digital temperature compensation and nonlinearity correction technology are used to ensure the reliability and accuracy of the measured value. The water-proof cable is connected to the transmitter housing, the transmitter can be immerged into the liquid for a long time. Integrated construction and standardized output signal provide convenience for application on site and automatic control.

LT10SR-2700 intelligent liquid level transmitter works in a two-wire system, the product has compact size, light weight and good stability; it can be used for water or liquid level measurement and control of petroleum, chemical industry, electricity, city water supply and drainage and hydrology, etc.
