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

Self- adjusting:

• 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
