Capacitance Probes with Flexible Time Delays for Covered and Uncovered Conditions

The dual timer capacitance probes feature a flexible time delay for covered and uncovered conditions, allowing the user to set a probe to react either immediately or with up to a 30-second delay when it detects a covered or uncovered state. The unit is ideal for applications when it is essential for the probe to alert immediately to a covered state when used for high level detection, as in situations when the probe is used to shut off a filling process. When the probe reaches an uncovered state, that same probe can be set to alert with a selectable one-second to 30-second delay. An immediate alert or timed delay can be applied to either the covered or uncovered condition. The probes offer interference-free, fail-safe operation & "Quick-Set" calibration. The capacitance sensors are used for high and low level detection in bins, silos, tanks, hoppers, chutes and other vessels used for material storage or process manufacturing. A wide assortment of probes and extensions make these capacitance probes appropriate for a variety of solid, liquid and slurry materials.
