Description of LEFOO Level Temperature Transmitter

Liquid temperature level transmitter LFT3200 housing the piezoresistive pressure sensor and PT-100 temperature sensor in one robust 304/316 steel housing. The transmitter will experience the liquid temperature and pressure then convert them into standard (current or voltage) signal output through a dedicated signal conditioning circuit. LEFOO transmitter LFT3200 adopts precise digital temperature compensation and is capable of a wide operating temperature range. Various output signal options to meet customers' requirements. 

Adopt oil-filled diffusion silicon core with high precision and high overload capacity

Temperature and pressure dual output, compact structure, saving installation space

Support Modbus-485 communication protocol (intelligent type)

The temperature-sensitive element and the pressure-sensitive element are packaged as a whole, which is closer to the temperature of the medium

Customized solutions for continuous level measurement and point level detection

Optimum solutions thanks to unique technology selection

Easy to integrate with matching process connection

Economical standard sensors, flexible customization

Application of Liquid Temperature Level Transmitters

Capable media such as crude oil, food, water.

Sealed tank with liquid stock applications.

Cisterns for water processing systems.
