Pressure and Vacuum Switches for Process Applications
SOR® pressure switches
are rugged, field-mounted instruments. The
pressure sensing element of the SOR pressure
switch is a force-balance, piston-actuated
assembly. The sensing element is sealed by a
flexible diaphragm and a static o-ring. A wide
selection of wetted parts materials for media
compatibility and containment are available. A
metal diaphragm may be welded to the
pressure port for certain applications, thereby
eliminating the o-ring.

Pressure and Vacuum
Switches
Glossary of Terms
SOR recognizes that there is no industry convention with respect to terminology and definitions
pertinent to pressure switches. This glossary applies to SOR pressure switches.
Pressure Switch
A bi-stable electromechanical device that
actuates/deactuates one or more electrical
switching element(s) at a predetermined
discrete pressure/vacuum (set point) upon
rising or falling pressure/vacuum.
Adjustable Range
The span of pressure between upper and lower
limits within which the pressure switch may be
adjusted to actuate/deactuate. It is expressed
for increasing pressure.
Set Point
That discrete pressure at which the pressure
switch is adjusted to actuate/deactuate on
rising or falling pressure. It must fall within
the adjustable range and be called out as
increasing or decreasing pressure.
Dead Band
The difference in pressure between the
increasing set point and the decreasing set
point. It is expressed as typical, which is an
average with the increasing set point at
mid-range for a pressure switch with the
standard K switching element. It is normally
fixed (non-adjustable).
Fire-Safe
The ability of a welded seal pressure sensor to
contain the process at elevated temperatures
up to 1900°F at the rated overrange pressure,
unsupported by the body of the pressure switch.
Hermetically Sealed
A welded steel capsule with glass-to-metal,
factory-sealed electrical leads that isolates the
electrical switching element(s) from the
environment.
Proof Pressure
The maximum input pressure that may be
continuously applied to the pressure switch
without causing leakage or catastrophic
material failure. Permanent change of set
points may occur, or destruction of the device
may be rendered inoperative.
Repeatability
The ability of a pressure switch to successively
operate at a set point that is approached from
a starting point in the same direction and returns
to the starting point over three consecutive
cycles to establish a pressure profile.
Repeatability on SOR switches will be smaller
than 1% of full scale per ISA/ANSI S51.1.
SPDT Switching Element
Single-Pole, Double Throw (SPDT) has three
connections: C — Common, NO — Normally
Open and NC — Normally Closed, which
allows the switching element to be electrically
connected to the circuit in either NO or
NC state.
DPDT Switching Element
DPDT is two synchronized SPDT switching
elements which actuate together at increasing
set point and deactuate together at decreasing
set point. Discrete SPDT switching elements
allow two independent circuits to be switched;
i.e., one AC and one DC.
The synchronization linkage is factory set, and
is not field adjustable. Synchronization is
verified by connecting test lamps to the
switching elements and observing them go
“On” simultaneously at actuation and “Off”
simultaneously at deactuation.
Overrange
The maximum input pressure that may be
continuously applied to the pressure switch
without causing permanent change of set
point, leakage or material failure.

This table is a listing of piston-spring combinations and the corresponding adjustable ranges, dead bands,
overrange and proof pressures. SOR vacuum switches are compound; they will operate in either vacuum or
pressure modes. The adjustable range is expressed from maximum vacuum decreasing to zero gauge and
increasing to maximum pressure. Dead band is expressed as typical. See dead band considerations below.
The set point must be within the adjustable range. A vacuum switch is generally better suited than a pressure
switch for set points very near zero gauge.

4. Diaphragms may have an additional effect on dead band. See page 13, Note 9.
5. Metric bar (mbar) values are practical equivalents of the reference English values; not necessarily exact mathematical conversions. This data appears on the product nameplate when metric engineering units are specified.
Dead Band Considerations
1. Dead band values are expressed as typical expected at
mid-adjustable range using the standard K switching element. When optional switching elements are specified, corresponding dead band multipliers must be applied.
2. Dead bands are fixed (non-adjustable), except when T or H switching elements are used.
3. Dead band can be adjustable by selecting T or H switching element. (Diaphragm life may be limited when used with Numbers 1 and 9 pistons.)
4. Dead band multipliers must be applied to the typical dead band value shown for piston spring combination in specifications, pages 7 and 8, whenever optional switching elements other than K, KA or W are used.
5. Dead band can be widened by selecting an optional switching element with a multiplier greater than 1.0.
Example:
Model 6NN-G5-M4-C2A-YY
Typical Dead Band 1.4 psi
G-Switching Element multiplier = 3
Corrected Typical Dead Band 1.4 x 3 = 4.2 psi

diaphragm system. See page 15.
5. Other diaphragm and o-ring combinations may be available. Consult the factory or the SOR
representative in your area for more information.
6. Wetted parts have been selected as
representing the most suitable commercially
available material for use in the service intended.
However, they do not constitute a guarantee
against corrosion or permeation, since processes
vary from plant to plant and concentration of
harmful fluids, gases or solids vary from time to
time in a given process. Empirical experience
by users should be the final guide. Alternate
materials are generally available.

Notes
1. Select designators for material and connection size. Large bold-face letters denote those items generally available from stock. Small light-face letters denote items with limited stock and possible
long delivery.
2. 1/4” and 1/2” tapered BSP(F) pressure ports are available. Consult factory.
3. Combinations are possible when a particular connection size is not available for the range (piston spring) desired. For example, if 2” NPT(F)
is desired for a Number 4 piston, the Number 12 pressure port can be supplied. The piston would be designated as Number 124 and the overrange and proof pressures for Number 12 apply. Note: 124, 125 and 126 are the only available
combinations.
4. Many other materials such as PVC, Kynar, etc., are available. Denote materials not shown by specifying an X followed by the required
connection size, and describe the material.
Examples:
X2A = PVC pressure port with 1/2” NPT(F) connection.
X1A = Titanium pressure port with 1/4” NPT(F) connection.
Non-metal pressure ports generally reduce proof pressure and may reduce overrange pressure. The pressure port material may limit the process temperature. Delivery may be longer than normal.
5. Raised-face and flat-face flanges to match ASA 150
and ASA 300 lb. in commercially available materials
can be supplied on Series 12 and 4 pistons by
adding an X suffix to the model numbers and
specifying “X - (size) inch (material) (raised- or flat-)
face flange to match ASA (rating) lb.”
6. Brass not available on Piston Numbers 9 and 1.
7. 1/4” NPT(F) Flushing Port standard on C6A pressure ports.

Description
Welded Flush-Type Diaphragm System
A metal diaphragm is welded to the process face of the pressure port, thereby,
eliminating the o-ring. This arrangement may be indicated for viscous or slurry
process where cleanliness is required or where process build-up and clogging is
unacceptable.
The pressure port designator determines the material: Only 1” NPT(M) 316SS is
available.
Example: U7-C4A
U7 = 316SS welded flush-type diaphragm
C4A = 1” NPT(M) 316SS pressure port
Note: U7 is limited to Numbers 5 and 6 pistons and the K switching element. Not
available on vacuum switches.
Fire-Safe Welded Diaphragm System
Factory Mutual System Approved - U.S Patent Number 4,438,305
Tested in flames at 1900oF for periods up to 30 minutes while pressurized to the
rated overrange pressure.
A metal diaphragm, the cylinder disc and the pressure port are welded as a unit,
thereby, eliminating the o-ring. This arrangement may be indicated for extremely
corrosive, hot, harsh or volatile process where o-rings are not suitable. See firesafe definition on page 6.
316SS is stocked. Hastelloy B and C, and Monel are available, but may require a
longer lead time. The pressure port designator determines the material.
Example: U8-C2A
U8 = Fire-safe welded diaphragm system
C2A = 1/2” NPT(F) 316SS pressure port
Note: 1/2” NPT(F) is stocked; 1/4” NPT(F) is not stocked and has a longer lead
time. Not available on Number 1 piston and vacuum switches.
Welded Diaphragm System
A metal diaphragm is welded to the pressure port, thereby, eliminating the o-ring.
This arrangement may be indicated for extremely corrosive, hot or harsh process
where o-rings are not suitable.
316SS is stocked. Hastelloy B and C, and Monel are available, but may require a
longer lead time. The pressure port designator determines the material.
Example: U9 - A2A
U9 = Monel welded diaphragm
A2A = 1/2” NPT(F) Monel pressure port
Note: Not available on vacuum switches.
C6A
Two-inch Pressure Port
The wide pressure port minimizes the possibility of clogging when the process media is sludgy or
viscous. See page 20 for dimensions. A 2” NPT(F) pressure port with a 1/4” NPT(F) flushing port
can be supplied with a welded diaphragm, or with a conventional diaphragm and o-ring combination.
