Kem Kuppers WT.02/WI.02 Local Converters Passive 4 - 20 mA sensors

 




The local converters type WT.02/WI.02 are passive 4 - 20 mA sensors with carrier-frequency-input stage (WT.02) or inductive input stage (WI.02).

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

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

In addition to the analogue output the sensors provide a galvanically isolated open collector output, which can be used either as a switch or frequency output. The frequency output is freely scaleable. This scaleable output allows a calibration to the volume flow independent of the type of flow meter.

The W*.02 have an interface integrated in the M12 sensor plug. The interface adapter and remote software KEM »EasyControl« allow for programming the operating parameters and to read the input frequency and temperature.

Both analogue and frequency output can be linearized with up to 20 points. When ordered with a flow meter the W*.02 output will be adjusted to this meter.

WIE



The local converters type WIE-** are passive 4 - 20 mA sensors with inductive input stage. The pre assembled sensor cable allows for a fast connection of the inductive sensor series “IF*”.

Consequently the WIE-** sensor is able to measure and evaluate flow rates with a medium temperature up to +350 °C [+662 °F].

In addition to the analogue output which is proportional to the flow rate the sensors provide a digital output, which can be used either as a switch or frequency output. The frequency output is freely scaleable and allows a standardisation of the frequency value.

The WIE-** have an interface integrated in the M12 sensor plug. The interface adapter CON.USB.WT and remote software KEM »EasyControl« allow for programming the operating parameters and to read the input frequency.

Both analogue and frequency output can be linearized with up to 10 points. When ordered with a flow meter the WIE-** output will be adjusted to this meter.
