The PROCAP capacitance probe with a flexible, extendable cable is designed for high, mid or low level detection when the capacitance probe must be mounted on the top of the bin. The flexible probe is ideal for applications where a probe is used as a high level alarm or needs to be extended more than four feet. It is ideal for use with any lump material that might bend, damage or break a rigid probe and is configured so the first 10 inches of the probe are rigid and the rest of the probe is flexible. The flexible ¼-inch diameter cable can be any desired length up to a 35-foot maximum extension, which is sensitive to the end of cable when uncovered. For convenience and ease of installation, the cable can be cut to the desired length in the field. A stainless steel flexible cable option for food and other sanitary applications is available.
