Bedia capacitive level sensors

Bedia’s capacitive level sensors are designed to be practically maintenance free and have a wide operating temperature range. They respond to the change of capacitance occurring when an electrode surrounded by air is immersed into the medium to be monitored. The various versions can be used as MIN/MAX sensors with closed circuit principle.

The level sensors are factory-preset as a minimum or maximum sensor with an open circuit or closed circuit principle and have a short circuit-proof switching transistor output.

Bedia manufactures a wide range of level sensors to suit many applications. Tube Sensor TLS100 detects the presence of a liquid in a plastic tube. These plastic tubes may also be mounted as a by-pass on a compensator in order to signal the required medium level in containers. Level Sensor NR80 is designed to monitor a preset medium level for liquids with a high relative dielectric constant in electrically non-conductive containers with a wall thickness up to 5 mm, and is fitted outside the container. Level Sensor NR150 is suitable for liquids with low relative dielectric constant. Level Sensor NR160 is designed to monitor liquids and powders with high relative dielectric constant, and Level Sensor NR260 is designed for use in fuel cells.
