Application

• Screenings container, 2.5 x 2.5 x 4.0 m (w x h x d)
• Medium: solid mixture
• Bulk cone with undefined angle
• Ex-Zone 1

Definition of tasks

• Level detection inscreenings container for overflow monitoring and to control container exchange
• Contactless measurement
• Sensors connected directly to PLC without extra transmitter and separation barrier
• Cost-efficient and reliable solution

Solution

• The contactless intelligent ultrasonic 2-wire sensor Type i-06 Ex was used.
• Due to the deep container and the mostly steep bulk cones, it was necessary to install 2 sensors with alignment aids at both ends of the container.
