PROCAP I & II Capacitance
Probes 
Interference-Free, Fail-Safe
Operation & "Quick-Set" Calibration
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 PROCAP I and II 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. It also provides fail-safe
protection in the event of a power failure as well as an
adjustable time delay to help prevent false readings.
