BD SENSORS has developed the stainless steel submersible probe LMP 307T for continuous level and temperature measurement in water and in clean or lightly polluted fluids. The advantage: simultaneous recording of level and temperature with separate independent signal amplification. The maintenance and wiring costs are considerably reduced. In addition to classical signal processing of the level, an additional signal circuit independent of the level which converts the temperature signal into a 4-20 mA analogue signal in 2-wire technology is provided. Typical application areas are, for example, drinking water purification, monitoring of rain spillway basins or river courses and level measurement in containers or tank batteries.
