توضیحات محصول

Applications
The WIO sensor measures the water content in the oil
and converts the value into an analog current signal. The
two sensor conductors are for power supply as well as
for carrying the signal to the measuring device or
controller. The sensor measures the water content from
0 to 20 %. It also sends a signal if the water content is
outside the normal range (warning), or if there is air in
the oil chamber (alarm). The sensor is fitted in a
stainless steel tube for mechanical protection.
It also has also special operation state, if the sensor is in
air (no oil detected), or the water content is more than
the measurable level (>20%).
Intended use
The sensor is normally used together with the Grundfos
IO 113 module, but it can also be used together with
other controllers with inputs of 4 to 20 mA.
Operation with standard controllers will miss the special
air detection state (3,5mA output from WIO), and over
20% water detected state (22mA).
Together with the IO 113, the sensor filters the signal
and provides an easy readout of the actual value.
Furthermore, it is possible to set a user-defined warning
limit and calibrate the IO 113 and the sensor to the oil .
The IO113 gives special warning signal in case of air
detection (blinking yellow indicatior).
