PROCAP IX & IIX
Capacitance Probes 
CSA Listed for Class I &
II Hazardous Locations
BinMaster PROCAP IX and IIX capacitance sensors are designed
for use in hazardous locations, featuring CSA Class I, Groups
C & D and Class II, Groups E,F & G ratings. They
are suitable for challenging environments where there is
a risk of explosion, detecting high and low levels in bins,
silos, tanks, hoppers, chutes and other vessels used for
volatile material storage or process manufacturing. BinMaster
capacitance sensors 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. A wide assortment of probes and extensions
make BinMaster capacitance probes appropriate for a variety
of solid, liquid and slurry materials.
These intrinsically safe 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 an internal 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.
