 Thermo
Ramsey's "CAP" Series Capacitance Level Control is designed
for point level monitoring of solids, fluids or slurries in
bins, vessels and chutes. The CAP Capacitance
Level Control can
eliminate spills, material waste, and down time by preventing
bin overflows, plugged chutes and empty bins. The CAP Capacitance
Level Control works
equally well as a high or low level indicator in plastics, food,
chemicals, mineral slurries, or other materials.
CAP Capacitance
Level Control detects the presence or absence
of material by sensing a change in capacitance caused by the
difference in dielectric constant of the vessel material and
air. To detect these small changes, the CAP series sensors use
a unique detection circuit that operates at a relatively low
frequency level (6 KHz). Unlike other capacitance sensors, the
operating frequency of the CAP Capacitance
Level Control series is well below the RF level
and not subject to FCC regulation.
The Thermo
Ramsey CAP Capacitance
Level Control series have a Fail-Safe feature
to eliminate problems caused by power disruptions. The high/low
selector switch allows the sensor to be set for fail-safe for
low, when material is absent, or high, when material is present.
