The KQ10 from ifm electronic enables continuous level monitoring from outside the process. It is designed to ‘see’ through all non-metallic walls, to detect granulates or liquids, without contact. Non-contact detection has the added benefit of obviating maintenance requirements.
The KQ10 sensor from ifm South Africa provides for non-contact monitoring of point levels in non-metallic tanks or vessels.
Process values of 0...100% can be transferred continuously via IO-Link over the entire length of 250 mm without dead band. 20 LEDs display the real level inside the vessel directly at the sensor. If several KQ10 units are combined, the detection zone can be increased accordingly.
Up to three point levels can be monitored with just one sensor, where normally three sensors would be needed, and this is achieved at the same time as continuous range monitoring. As well as the switch points, other functions such as NC/NO, hysteresis or the orientation and detection zone of the sensor can be set.
Where the typical conventional solution includes two point level sensors each at the lower (empty) and upper (overflow) ends of the tank, a single KQ10 includes three switch points to indicate empty, full and overflow conditions. This reduces the number of sensors required and installation complexity. Moreover, the KQ10 continuously measures levels in ranges of 250 mm and provides these, in addition to the switching states, as a percentage value, via IO-Link.
Slight deposits on the inner walls of a tank do not impair the level detection and they can be signalled via the switching output or IO-Link if the threshold is exceeded. This permanent condition monitoring helps to prevent unplanned production downtime.
