Float-Operated Level Switches
Model Series 100, 200 and 300
The float rides on the process liquid surface,
precisely tracking liquid surface motion.
Rising liquid level lifts the float, sliding the attraction
sleeve up inside the enclosing tube and into the
magnetic field to actuate the electrical or
pneumatic switch (signaling liquid presence).
Subsequently, falling liquid level lowers the float,
drawing the attraction sleeve out of the magnetic
field to deactuate the electrical or pneumatic switch
(signaling liquid absence). Float-type level switches
are generally able to handle high-temperature
applications, and sometimes prove useful for close
interface detection.
Floats can operate up to three switching elements.
Independent switching levels may be obtained with
tandem floats. Consult the factory for special floatswitching arrangements.

Displacer-Operated Level Switches
Model Series 700, 730, 740, 750 and 800
Displacer controls offer alternative features to
the float-operated control. The sensor is a
weight (displacer), heavier than the liquid, that
is suspended by a spring. When liquid contacts
the displacer, a buoyancy force is produced,
which causes the effective weight of the
displacer to change. This causes the spring to
retract slightly to a new equilibrium position.
When the spring retracts, the attraction sleeve
also moves upward into the field of the external
magnet, thus overcoming the force of the bias
spring and actuating the switching element.
This principle provides for narrow or wide
switching differential, and allows switching point
alteration by moving the displacer(s) up or down
the suspension cables.

Switching Mechanisms
SOR switching mechanisms are designed for use in harsh industrial atmospheres. SOR offers a
variety of electrical and pneumatic switching mechanism types to fit a wide range of applications.
The basic types of switch mechanisms available are listed below. See page 47 for specifications.
All SOR switching mechanisms are constructed from stainless steel and other durable
manufactured materials. Each mechanism is individually calibrated and inspected to insure
accuracy and repeatability. See below for the benefits and application of each switch type.
All mechanisms are interchangeable with most competitor units.
Standard Dry-Contact Switches
Types A, B, C, E
Standard dry-contact switches have open mechanisms and
exposed switching elements. These switching mechanisms are
easy to maintain. Visual confirmation of operation is obvious.
Dry-contact switch mechanisms are recommended for most level
switch applications and are available in SPDT and DPDT switch
arrangements.
Dry-Contact Switch Mechanisms feature:
High-load carrying capacity
High-quality phenolic insulator
Vibration resistance
Versatility of application
Mini-Hermetically Sealed Switches
Types L, S, T, V
Mini-hermetically sealed switches have a hermetically sealed
switch element on an exposed mechanism. Good for hightemperature service and normal applications that require
hermetically sealed contacts.
Mini-Hermetically Sealed Switch Mechanisms feature:
Rugged stainless steel construction
Class I Group A rating for use in hazardous areas
Vibration resistance
High operating temperature limits
Anti-Vibration Switches
Types D and R
Anti-Vibration Switches employ two magnets to provide
vibration protection. Dual magnets prevent false trips by
providing a positive mechanical lock to the enclosing tube
when the switch is in any position.
(Type T switches are mini-hermetically sealed units with
dual magnets.)

Type J
Pneumatic switches are available for applications that prohibit
electrical switching or where electricity is not available.
Pneumatic switches feature:
Three-way aluminum valve
Anti-vibration design
1/4" NPT ports in 316SS for additional
corrosion resistance
Extra-High Temperature Switch
Type Y
The Y Series level switch mechanism is designed to
operate normally under extremely high-temperature
conditions. Constructed of stainless steel, ceramic, and
oxidation-resistant alloys, the Y Series is designed to
counteract the warping and seizure normally associated with
this type of mechanism in high temperatures. The Y Series
switch is especially well suited for power plant conditions.
Y Series Switch Mechanisms feature:
Mica/glass insulation on wires and switches
Stainless steel and ceramic switch element

High Temperature Selection
SOR level switches can accommodate high-temperature applications up to 1200oF (649oC).
These temperatures may be safely reached by a proper combination of chamber material, switch
mechanism and temperature extension. Refer to page 52 to select the proper components for your
process temperature.
ET Accessory
The straight temperature extension provides physical distance
between the process and the switching mechanism. It is
constructed of a straight piece of pipe welded between the
chamber and enclosing tube connection.
How It Works
The straight temperature extension is designed to remove the
switch from direct radiant heat in dry heat processes. Consult
the chart on page 52 for application.
To Specify
Add Accessory Designator ET to the end of the SOR level
switch model number per the selection chart on the next page.
The ET accessory automatically matches the material and
rating of the specified level switch chamber. This option can
be supplied on SOR level switches Series 100, 200, 300
and 400.

The finned temperature extension is designed to protect the electrical portion of a level switch
from heat damage due to condensing processes. When used in combination with high-temperature switch
mechanisms, this option allows operation in process temperatures up to 1200oF (649oC).
How It Works
The finned temperature extension condenses process steam and
reduces its heat before it can reach the switching mechanism.
The design reduces steam to its saturation temperature in the
enclosing tube, protecting the switching mechanism from
deterioration due to high temperatures. The process
pressure dictates the saturation temperature, see page 58.
To Specify
Add Accessory Designator FE to the end of the SOR
level switch model number per the selection chart on the
next page.
The finned temp. extension automatically matches the material
and rating of the specified level switch chamber. These options
can be supplied on SOR level switches series 100, 200,108/208,
300 and 400.
Note: For proper cooling, temp. extensions must not be insulated
or placed inside an enclosed structure. High ambient temperatures
(over 100
adjacent piping or vessels will affect cooling performance.
Consult the factory if any of these conditions exist.

High Temperature Selection
There are two sections to the chart, Steam Heat and Dry Heat. Fundamental differences in condensing
(steam) and non-condensing (dry) heat require different methods of protection.
Steam Heat processes carry it’s heat with the vapor. These processes effectively heat every portion of their
enclosure. To reduce the heat effects of condensing processes, we must either condense or physically block
the vapor. SOR uses a condensing system to avoid the sealing problems associated with blocking the steam.
Dry Heat processes transfer heat through direct conduction. Heat is only passed to the areas where they
touch the enclosure. Therefore, radiant heat is the only concern with these processes. This may be resolved by
adding distance between the process and the protected portion of the control.
To use the selection chart, first select the column that represents the desired maximum temperature. Select
a chamber material that is allowable in the chosen column. Move down to the proper process type section,
Steam Heat or Dry Heat. Within that section, select a switch mechanism from those listed in the chosen
column. The symbol will indicate if a temperature reduction device is required.

Category D A fluid service in which all of the following apply:
1. The fluid handled is non-flammable, non-toxic, and not damaging to human skin.
2. The design gage pressure does not exceed 150 psi.
3. The design temperature is between -20°F and 366°F.
Category M A fluid service in which the potential for personnel exposure is judged to be
significant and in which a single exposure to a very small quantity of a toxic fluid,
caused by leakage, can produce serious irreversible harm to persons on breathing
or bodily contact, even when prompt restorative measures are taken.
Severe Cyclic A fluid service with high-cycle rates that cause extreme stress on components.
High Pressure
specified temperature and material group or any piping so designated by the customer.
Pressure in excess of that allowed by the ASME B16.5 Class 2500 rating for the
Weld Examination
When CY or CZ is specified, SOR performs examination to meet these codes. This includes visual
inspection and ultrasonic, X-ray, magnetic particle or dye penetrant testing as required by ASME
B31.1 or B31.3. If CY or CZ is not selected but examination is required, accessories UT (ultrasonic),
RT (X-ray), MT (magnetic particle) or PT (dye penetrant) can be added to the model number to
include this testing.
Hydrostatic Testing
SOR performs a hydrostatic pressure test on all welded chambers at 1.5 times the design pressure
for three minutes. CY and CZ options and Hydrotest Certificates include a hydrostatic pressure test
at 1.5 times the design pressure for ten minutes as required by ASME B31.1 and B31.3 codes. A
hydrostatic test certificate is also available as an accessory. See Test Certificates, Form 1254.

MC and TC Options
702A-AIC-B-A1-MC-CRTT
Manual Check (MC) and Tru-Check (TC) options permit manual actuation of vertical displacer level
switches, addressing EPA and OSHA safety requirements. The standard 30-foot stainless steel
chain allows manual actuation from the tank base, eliminating potentially hazardous trips to the top
of the tank. Specify either an MC or TC option by placing the designator in the accessory section of
the model number.
Designator Application
TC Tanks or vessels pressurized to 100 psi
MC Atmospheric vented tanks or vessels
These options are available on SOR level switch Series 701 through 704 and 730 through 733. MC and
TC option available on carbon steel units only. Series 730 through 733 are more sensitive to both high
and low SG values. Please consult factory before ordering the MC or TC options for these models.
How It Works
Pulling the handle transfers downward motion to the actuator lever by means of the beaded
stainless steel chain. The resultant motion lifts the entire level sensing assembly which moves
the attraction sleeve and actuates the switching element to simulate a high-level condition.
Switching action for alarm, shutdown or control is verified.

Specific Gravity of Water
The specific gravity of water changes depending on its temperature and pressure. The chart below
lists properties of saturated steam. Saturated steam is the state where water is in transition between
liquid and vapor. The chart provides the process temperature with the associated pressure and specific gravity of the condensate water. If a water application has a high temperature and low pressure,
condensate will only be present at the temperature that corresponds to the maximum pressure.
Select the proper row based on the temperature and pressure, and read the specific gravity.
Figures are based on saturated steam.
