passive signal converter / transmitter
Our level indicators can optionally be equipped with magnetic switches or with transmitters for a continuous electrical signal. A new, compact converter is now available for WEKA's 3-wire transmitters. The converter feeds the resistance chain of the instrument with a constant current. The transmitter supplies a voltage via the signal conductor analogous to the level in the float chamber, which is then converted into a passive 4...20 mA current signal. This standardized current signal (NAMUR) is less sensitive to interference, which has a positive effect on the stability of the system.
