BinMaster’s 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. They operate by detecting the presence or absence of material in contact with the probe by sensing minute changes (as low as 0.5 pF) in capacitance caused by the difference in the dielectric constant of the material versus the air. Class II hazardous location ratings and a wide assortment of probes and extensions make these capacitance probes appropriate for a variety of solid, liquid and slurry materials.
BinMaster 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 a visual LED to indicate sensor status. Accurate level detection is assured even in dusty, sticky or clinging materials by the PRO-Shield feature which compensates for material build up on the sensing probe. They provide fail-safe protection in the event of a power failure as well as an adjustable time delay to help prevent false readings.
Standard models include the PROCAP I & II. For hazardous locations, the PROCAP IX & IIX feature CSA Class I, Groups C & D and Class II, Groups E, F & G ratings. The PROCAP I 3-A & II 3-A meet rigorous USDA, FDA and 3-A material & design standards for sanitary food and dairy processing. The PROCAP I-FL & II-FL offer “no probe intrusion” and are designed for space constrained areas or applications where material flow or bridging may damage a standard probe.

The SC700 series are capacitance point level switches ideal for detection or control of liquids, solids, heavy pastes or slurries. Unlike other capacitance probes, the SC700 works for any type of conductive, non-conductive or low dielectric materials with extremely accurate performance, almost complete immunity from build up, temperature changes or condensation. The rigid rod is made with a strong and durable plastic (polyacethal delrin) for standard units or upon request the rod can be made with PTFE.
Features
*Simple to install & low in cost
*No moving parts-maintenance free reliability
*AC, DC or a Universal power supply version
*Extended versions available with rigid rod or cable
*Operating temperatures 14 to 200ºF (-10 to 95ºC)
*Maximum pressure of 725PSI (50 bar) up to 8000PSI upon request.
*Sensitivity as well as Time Delay adjustments
*Does not require an external reference in plastic or concrete vessels
*Available in threaded, sanitary and flanged process connections

The LS provides level verification for a variety challenging sanitary applications. Minimally invasive, the LS is designed for both tank level detection and pipeline product monitoring. Suitable for many water-based fluids, the LS also detects minimally conductive and viscous or foamy media. Standard with a PNP transistorized output the LS easily wires directly to a PLC and is available with a LED for local level indication.
