BinMaster’s PROCAP capacitance probes are an affordable, flexible solution for level detection in bins, tanks and silos. The probes detect 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.
The PROCAP probes are designed with features that make them accurate and reliable, even under rigorous or harsh conditions. An LED light on top of the unit indicates the sensor status is covered, uncovered, or in a failed condition preventing process mishaps caused by a power failure. Pro-Shield protects against false readings due to buildup on the probe or bridging between the sidewall and the probe. A time delay feature minimizes false signals from sudden material shifts or splashing liquids. Further, the PROCAP probes are immune to RF signals, ensuring interference-free operation from electronic plant equipment or two-way radios.
Class II hazardous location ratings and a wide assortment of extensions can be custom built to user specifications making these point-level sensors appropriate for a variety of solid, liquid and slurry materials. BinMaster’s PROCAP capacitance probes are mounted on the top, side or cone of the vessel for high-, mid- or low-level detection. BinMaster, www.binmaster.com
