SOR® Pressure Switches
are rugged fi eld-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 fl exible 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.
Application Information
The SOR pressure switches in this catalog are suitable for a variety of process applications. Basic models with standard wetted parts are normally suitable for air, oil, water and non-corrosive processes. See the Quick Selection Guide on pages 4 and 5. Specifi c application requirements can normally be met by selecting optional components, such as switching elements, diaphragm systems and pressure ports. See How to Order on page 3. Certain applications may require customized specials. Consult the SOR representative in your area or the factory.

Glossary of Terms
SOR recognizes that there is no industry convention with respect to terminology and defi nitions 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 can 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 fi xed (non-adjustable).
Fire-Safe
The ability of a welded seal pressure sensor to contain the process at elevated temperatures up to 1200°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.
Overrange
The maximum input pressure that can be continuously applied to the pressure switch without causing permanent change of Set Point, leakage or material failure.
Form 216www.sorinc.com 913-888-2630Proof Pressure
The maximum input pressure that can be continuously applied to the pressure switch without causing leakage or catastrophic material failure. Permanent change of Set Points may occur, or 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 profi le.
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 fi eld adjustable. Synchronization is verifi ed by connecting test lamps to the switching elements and observing them go “On” simultaneously at actuation and “Off” simultaneously at deactuation.

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. 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.

1. Dead band values are expressed as typical expected at mid-range with the standard K switching element assembly installed. When optional switching elements are specifi ed, corresponding dead band multipliers shown below must be applied.
2. Special ranges may be possible. Consult the factory or the SOR representative in your area.

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 specifi ed.
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 specifi ed, corresponding dead band multipliers must be applied.2. Dead bands are fi xed (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 specifi cations, 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 psi6. See item #9, page 7.

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 fl uids, gases or solids vary from time to
time in a given process. Empirical experience by users should be the fi nal 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.
Form 216
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 fl at-face fl anges 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 suffi x to the model numbers and specifying “X - (size) inch (material) (raised- or fl at-) face fl ange 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.
