capacitive level switch / for liquids / for solids / explosion-proof

These intrinsically safe capacitance probes provide interference-free operation, working far below the RF level of 9 KHz at just 6 KHz, and will not interfere with two-way radios or other equipment operating in the radio spectrum. They feature simple ?quick set? calibration and fail-safe operation, including an internal LED to indicate the sensor status.

Accurate level detection is assured even in dusty , sticky or clinging materials by the PRO-shield feature, compensating for material build up on the sensing probe. These probed deliver fail-safe protection in the event of a power failure, and adjustable time delay to help prevent false readings. These products are suitable for challenging environments where there is a risk of explosion, detecting high and low levels in bins, silos, tanks, hoppers, chutes and other vessels used for volatile material storage or process manufacturing.
