There is no shortage of level control technologies in the process control market, for either simple point level or continuous measurement of the level, and perhaps one of the favourites that can do both is GWR, or guided-wave radar. The benefits of such a system lie in several factors. Firstly, few substances absorb the signal, guaranteeing detection. Secondly, the waves will pass around any deposits that might adhere to the antenna, so they do not disrupt the true measurement. In addition, the antenna itself can be cut to the right length for the vessel. The GWR system can also ignore foam on the medium.
The LR series all consist of a modular system with evaluation unit and probe. The stainless steel evaluation unit offers an intuitive pushbutton setting interface and a clearly visible 4-digit LED display. Sensor parameters are also accessible remotely over IO-Link.
The evaluation unit provides different output combinations depending on the model: standard output functions available are two programmable switched outputs, or one switched output and one scalable analogue (4…20 mA). Alternatively, IO-Link can transmit the true value.
