NEW: Local Converters with Interface (WT.02 / WI.02)
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 (typ. < 0.5 Hz).
The inductive converters WI.02 are recommended for higher medium temperatures (up to +150°C).
The integral interface and the KEM EasyControl software allow for free programming.
Specifications:
- output signal: 4-20 mA, 2-wire (passive)
- operating voltage: 12-30 V, regulated
- measuring frequencies: 1 up to 3,000 Hz according to flow meter
- allowable load: 20 mA, max. 800 Ohm (Voltage dependent)
- response time: 250 ms (for input frequencies > 5Hz)
- ambient temperature: -20 up to +50°C
- medium temperature WT.02: -20 bis +120°C
- medium temperature WI.02: -20 bis + 150°C
