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.

The main product advantages:

► Economical:
– Cost-effective alternative to bus converters (HART®, Profibus®, Foundation Fieldbus®)
– simple and fast installation
– clever maintenance

► Robust:
– Reverse polarity secured and overvoltage protected
– no software, no updates, no start-up, no crash

► Selbstabgleichend:
– 4 mA position self-calibrating
– 20 mA position pre-set (re-adjustable)

► User-friendly:
– 3 LEDs indicate the current operating status
– Determination and indication of sensor errors by LED
– Error storage for diagnostic purposes
– Forwarding of error codes to the controller
