Single Point Level Controllers
Robertshaw offers 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. Robertshaw's cutting edge level instrumentation can accurately
measure conductive or non-conductive liquids and granular materials.
Robertshaw's 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.
The 310 Level-Tek is a remotely mounted, RF capacitance sensing, on/off control and display instrument.
The Robertshaw Model 310 LEVEL-TEK is an all new RF
capacitance sensing, on-off Control and Display Instrument.
Used primarily for detecting and controlling product level
changes in vessels or containers, it provides contact closure for
external control action by means of a DPDT plug-in type, dust
tight relay. The weather-tight unit has alarm lights. This
instrument is available with a choice of three supply voltage
variations, has adjustable differential (deadband) and
adjustable time delay (response time). All adjustments are
multi-turn by means of sealed potentiometers.
The 5100 Level-Lance is a microprocessor-based, advanced technology, on/off level detection instrument.
The 5100 Level-Lance is a microprocessor-based, advanced technology, on/off level detection instrument.
The Robertshaw Model 5100 Level-Lance is a
microprocessor based, advanced technology On-Off
level detection instrument. By utilizing the
microprocessor, the device can be calibrated without
screwdriver adjustments or knobs to turn. The
simplicity of the "Auto Set" calibration is the ultimate
in level control ease of adjustment.
The Model 5100 has eight (8) separate and individual programs preprogrammed into its memory. These programs let the user select the "type" of On-Off control action best suited for the application. The eight programs are field selectable by means of a 10 position rotary switch.

The Robertshaw Model 5318B Level-Tek is a RF
capacitance point (On/Off) level switch, which employs
all solid state electronics for detecting predetermined
product level changes in tanks, sumps, silos and other
vessels or containers. The Model 5318B is capable of
detecting a wide variety of products, including liquids,
powders, granular, lump and flake materials. The
product can be either conductive or non-conductive.
The Model 5318B is self-contained and uses microprocessor based digital circuits to ensure long-term stability, reliability and reduced maintenance. Control signals are provided through the contacts of a DPDT relay. The instrument features adjustable time-delays that are individually adjustable for both "Alarm" and "Return-to-Normal". There are either fixed or adjustable differential settings available. The unit is available for either AC or DC supply voltages.
