LEVEL CONTROLS
Robertshaw offers a complete line of RF and microprocessor based level
controls for continuous and/or point level control. All our microprocessor based
level systems consist of a sensing element and a patented PFM transmitter with
remote mounted level controller. The transmitter requires no primary power as it
is powered over the same two wires that transmit the digital pulses to the
controller. Transmission ranges one (1) mile without the use of coaxial or
triaxial cable. Solid State RF devices are single unit direct mount as well as
remote mount. A variety of sensing probes are available to suit your
applications; high temp/press, sanitary, flanged, inactive lengths, grounded for
non-metal tanks, rigid, flexible, bare or insulated.

TEMPERATURE/PRESSURE REGULATING VALVES
Robertshaw SATR's (self-actuated temperature regulators) have thermal systems
combining the responsiveness of vapor pressure and the positive action of liquid
transmission. Sylphon© seamless metal bellows actuators are offered in three
sizes to provide the correct combination of power, speed of response and
stability for many temperature control applications.
The full range of available valve styles includes sizes 1/4" thru
6", single-seated and double-seated in selected sizes. Direct and
reverse-acting valves are offered for heating or cooling service. A
single-seated fully-balanced direct-acting valve style MA, is standard for
3/4" thru 2" sizes. Three-way valves are offered for blending, mixing,
or diverting service. Robertshaw has now added stainless steel bodies in
1/2" thru 2".
Adjustable temperature ranges are provided from -35ƒ to as high as 480ƒF.
Exact range limits and setpoint adjustment spans are determined by operating
characteristics of individual regulator styles.
Temperature overrun protection is standard. A variety of thermal bulb styles
and armored capillary tube lengths up to 50 feet are offered.
- Model RT-1001-B1
-
- Two-way-single-seated and double-seated valves, direct and reverse-acting.
Three-way valves for mixing or diverting. Sizes 1/4" to 4" . Wide
throttling band for maximum stability. Approximately 60ƒF spans from -20ƒF
to 480ƒF.

VIBRATION SWITCHES & MONITORS
Robertshaw vibration detectors are designed to measure the total acceleratory
shock present on a machine. Acceleration measurements made by the vibraswitch
are the summation of all the individual accelerations giving a total destructive
force acting on the machine - the result is positive protection. When the
vibration level of a vibraswitch-protected machine exceeds normal operation by a
pre-selectable amount, an internal switch closes, actuating a shutdown circuit
before costly damages occurs.
The Robertshaw vibration equipment responds to destructive force, not
displacement. The units give continuous protection for operating machines. There
are no moving parts to wear out, ensuring long life of the instruments with no
maintenance required.
|
Robertshaw Vibration Instruments can be
used on rotating or reciprocating machines. To select
the proper instrument for your machine, follow the link
to
Selection Guide Matrix and/or follow the steps
below.
- Select the unit that meets the environmental
conditions that your machine is located in
[hazardous area (explosion-proof or I.S.) or
non-hazardous; temperature range].
- Select the power supply and/or remote reset
voltage required.
- Select the unit that provides you with the
required measurement type, range and frequency for
your machine. The type would be acceleration (G's)
or velocity (IPS). The range would be the G range or
IPS range. The frequency would be in Hertz (RPM of
machine ÷ 60).
- If you require time delays (Start, Monitor or
Start & Monitor delays – see note below),
select the instrument that offers that feature.
Models 375A/376A series offer fixed time
delays; Model 566 offers adjustable Monitor
Delay; Model 563A MUST BE used with Vibraswitch
Model 366 or 365, and provides adjustable
time delay for the units that are connected to the
563A Monitor. If time delay is not required
proceed to step 5 below.
- Select the function that you desire:
- Alarm or shut down only
by:
- Electrical SPDT or DPDT Switch Operation
(Models 365/366, Models 375A/376A with Start
Delay Only).
- Solid State Triac Switch Operation
(Models 375A/376A except for Start Delay
ONLY Model which has SPDT Switch Contacts).
- Pneumatic Operation (Model 368).
- 4-20 mADC output only
(Models 570B/571A).
- 4-20 mADC output with
alarm and/or shut down contacts, triac outputs
(Model 566).
- Check to see if the Model selected above has a
mounting configuration suitable for your
application. All units are surface mount except
for the following:
- Models 570B/571A are stud
mount.
- Model 563A Monitor is used
with the surface mount 365/366 Vibraswitches to
provide adjustable start and monitor time
delays.
- After you have made your
selection, review the complete Product Specification
Sheet to verify your selection is correct.
NOTE:
Start, Monitor, or Start & Monitor Delays are
used to prevent unwanted shut down or alarm during
start-up or normal operation of your machine.
- Start Delay:
Prevents unwanted shut down when excessive
vibration exists (which exceeds the set-point of
the vibration switch or monitor) during the
start-up of the machine.
- Monitor Delay:
Prevents unwanted shut down when short excessive
vibration spikes occur (which exceed the
set-point of the vibration switch or monitor)
during normal operation of the machine. Spikes
are typically caused by detonation, cavitation,
other machinery in the immediate area, etc.
