PROCAP IX & IIX capacitance sensors are designed for use in hazardous locations, featuring CSA Class I, Groups C & D and Class II, Groups E,F & G ratings. They 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. 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.
