Capacitance Probe for Sanitary Applications

Model: PROCAP I 3-A & II 3-A

The PROCAP I 3-A and 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, 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.

  • Point level detection and process control for solid, liquid and slurry materials
  • Used in bins, vessels, tanks, chutes and conveyors where 3-A and/or USDA approvals are necessary
  • Dairy products, food, pharmaceuticals, and many other materials requiring 3-A or USDA approvals
  • 3-A approved, food grade design
  • “Quick-Set” simple calibration
  • Triple thread screw-off cover
  • Dual conduit entrance
  • Unsurpassed sensitivity 0.5 pF
  • PRO-Shield compensates for material buildup
  • Operates below RF range, temperature stable calibration and protection from RF interference
  • Fail-safe, switch selectable high/low
  • Adjustable time delay to 30 seconds
  • Visual LED indicates sensor status: uncovered, covered or power failure
