Capacitive Level Sensor incorporates noise immunity feature.
December 19, 2008 -
Suited for level applications, BCF10 can detect liquids with high concentrations of chlorides - such as soaps and cleaners. This DC sensor, available with 10 mm range, comes in flat pack housing sized to facilitate flexible mounting. Compensating electrode configuration allows sensor to detect liquid level through any residual film left in containers. Corded and quick-disconnect versions are available.

New Flat Pack Noise Immune Sensor
Minneapolis, Minn.-December 10, 2008-TURCK introduces a new noise immune and easy to apply capacitive sensor for level applications. The BCF10 sensors small size makes it more flexible for mounting in level applications, and it has the ability to detect liquids with high concentrations of chlorides, such as soaps and cleaners.
TURCKs noise immunity technology has been used in barrel style sensors for years, but has recently been retooled for a flat pack housing, notes Melissa Schumann, product specialist with TURCKs sensors division.
In applications where a detergent high in chlorides is used, it is typically contained in a plastic container. Over time, the detergent leaves a film or etch on the inside wall of the container. If a standard capacitive sensor is used for level detection, it will detect this film even though the container is empty. The BCF circuit incorporates a compensating electrode configuration that allows the sensor to detect through the film and to the actual liquid in the container, adds Schumann.
The BCF10 is a DC sensor, available with a 10 mm sensing range in either a corded or quick-disconnect versions.
