Sanitary / Dairy

The PROCAP I 3-A & II 3-A meet rigorous USDA, FDA and 3-A material and design standards for sanitary food and dairy processing. They can be used for high and low level detection in bins, silos, tanks, hoppers, chutes and other vessels used for the storage or manufacture of food or dairy products. 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. They feature a Class II hazardous location rating and are available with a wide assortment of probes and extensions to meet a variety of processing needs.

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 the 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 also provide fail-safe protection in the event of a power failure, as well as an adjustable time delay to help prevent false readings.
