Local Converters (WT.02/WI.02)

programmable and with interface

The converters are passive 4 - 20 mA sensors with carrier-frequency-input stage (WT.02) or inductive input stage (WI.02). Both analogue and frequency output can be linearized with up to 10 points.

The carrier frequency converters WT.02 are recommended for low flow due to the low lower cut off frequency (type < 0.5 Hz).

The inductive converters WI.02 are recommended for higher medium temperatures (up to +150 °C [302 °F]).

The integral interface and the KEM EasyControl software allow for free programming.
