FLS C6.30 is a family of inductive conductivity transmitters which are made by a 4-20mA output device (two wire technology) integrated onto an inductive conductivity sensor. This type of measurement technology allows a broad range of applications especially to measure high values of conductivity (till 1000 millisiemens) in aggressive fluids (C-PVC is the only wetted material). As no electrodes are directly in contact with liquid, a reliable and stable measurement is guaranteed for a long operating time. A proper automatic temperature compensation (ATC) is granted by a Pt100 integrated into instrument body. The isolated 4-20mA output is perfect for direct connections to PLCs or data loggers without any extra interfaces. Transmitter as well as temperature sensor are supplied already calibrated.
