We offer RF capacitance level control technology
for virtually any substance in any type of vessel.
Solid state, digital designs offer on/off and
continuous level measurement in all types of
vessels. Our cutting edge level instrumentation
can accurately measure conductive or non-conductive
liquids and granular materials.
Our microprocessor based instruments feature patented PFM
(Pulse Frequency Modulation) transmitter technology. With
this technology, the transmitters convert the probe signal
to a variable period digital pulse output. These pulses
are transmitted via two ordinary wires (up to one mile
transmission capability) to the microprocessor controller.
The microprocessor manipulates the pulses and provides a
4-20 mADC signal, relay actuation for alarm, or both,
depending on the particular model. No primary power lines
are required as the unit is powered by the same two wires
that transmit the pulse to the controller. Set point data
is easily entered via a simple toggle switch, push button,
or keypad (depending on model), thereby eliminating the
need for tools and providing consistent results regardless
of operator skill. Robertshaw level instrumentation
accurately gauges liquids, powders, granular, lump and
flake materials.
