The Compact Pro is a compact capacitance probe designed for tight spaces. It is used for high or low level measurement and plugged chute detection for liquids, powders, granules, and pelleted materials. It is appropriate for use in tanks, bins, silos, chutes, conveyors, pipes, or load out hoppers. Its small size makes it easy to install and a simple ""one-time"" calibration procedure with sensitivity up to less than one picofarad ensures fast set up. A visual LED on the housing indicates sensor status at-a-glance, showing the presence or absence of material.
