LMK 307T Level and Temperature Transmitter Ceramic Sensor accuracy according to IEC 60770: 0.5 % FSO Nominal pressure / nominal temperature from 0 ... 4 mH2O up to 0 ... 250 mH2O from 0 ... 30 °C up to 0 ... 70 °C others on request The advantage: simultaneous recording of level and temperature with separate independent signal amplification. The maintenance and wiring costs are considerably reduced. Output signals 2-wire: 4 ... 20 mA (pressure) 2-wire: 4 ... 20 mA (temperature) Special characteristics ► separate output signals for pressure and temperature ranges good long term stability easy handling low maintenance and wiring costs different kinds of cables and elastomers 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. Preferred areas of use are Water drinking water systems ground water monitoring domestic water tanks rain spillway basin The stainless steel submersible probe LMK 307T with flush mounted ceramic sensor has developed for continuous level and temperature measurement in water or waste water applications. customer specific versions Sewage waste water treatment, water recycling dumpsite, waste water tanks Fuel and oil fuel storage, tank farm, biogas plants BD SENSORS GmbH BD-Sensors-Straße 1 D - 95199 Thierstein
