The robust KingCrown process indicator provides real-time information on the status of its sensor. The crown-shaped upper side is designed in a way that the LEDs, which are to communicate the information, are visible from all sides. Five predefined colours provide insight into whether the process is proceeding as intended and indicate the medium being measured. In addition to the LEDs, the sensors are equipped with an IO-Link-capable, stainless-steel electrical connection. A proprietary concept guarantees long-term tightness.
