PROCAP I 3-A &
II 3-A Capacitance Probes 
Meets 3-A Standards for Sanitary
Food or Dairy Processing
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.
