BD SENSORS has developed the stainless steel submersible probe LMK 307T with flush mounted ceramic sensor for continuous level and temperature measurement in water or waste water applications. 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.
