LMP 307T Level and Temperature Transmitter Stainless Steel Sensor accuracy according to IEC 60770: standard: 0.35 % FSO option: 0.25 % FSO Nominal pressure / nominal temperature from 0 ... 1 mH2O up to 0 ... 250 mH2O from 0 ... 30 °C up to 0 ... 70 °C others on request Output signals 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. 2-wire: 4 ... 20 mA (pressure) 2-wire: 4 ... 20 mA (temperature) Special characteristics ► separate output signals for pressure and temperature ranges easy handling low maintenance and wiring costs 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. Preferred areas of use are drinking water certificate according to DVGW and KTW different kinds of cables and elastomers Water / filtrated sewage drinking water system rain spillway basins water recycling customer specific versions BD SENSORS GmbH BD-Sensors-Straße 1 D - 95199 Thierstein Fuel and oil tank farm
