Description

The LCT 307i 485 combined transmitter is designed for continuous measurement of level, conductivity and temperature of mineral water in boreholes. It´s possible to measure water level in a borehole, pool or well by just one transmitter. Level of water, conductivity and water temperatures values are gradually sent to RS 485 bus by communication protocol Modbus RTU or HART, transmitter can handle both protocols simultaneously. For
measuring the water level is used the proven semiconductor sensor with stainless steel
separating diaphragm. Conductivity measurement is provided by a 4 wire sensor with platinum electrodes on ceramics. This arrangement allows accurate conductivity measurement within very wide limits. Level and conductivity channels are digitally temperature compensated. The temperature channel is fitted with a Pt 1000 sensor.
