How to Select a Pressure Switch for your Application
STEP 1 - SERVICE LIFE OF THE SWITCH
Expected service life is the first consideration to be made in
selecting a pressure switch, regardless of the pressure or sensitivity
desired. If the service life (the number of cycles the switch is
expected to operate) is one million or less, use of either a bourdon
tube or diaphragm switch is indicated. If a service life of more than
one million cycles is desired, a piston switch should be used. An
exception to this rule may be made when pressure change in a
system is very slight (20% or less, of the adjustable range). Under
such conditions a bourdon tube or diaphragm switch can be used
up to 2.5 million cycles before metal fatigue.
A second consideration in choosing a pressure switch is the speed
of cycling, regardless of the service life. If a switch is expected to
cycle more than once every three seconds, a piston type switch
should be specified. The metal of any bourdon tube or diaphragm
acts as a spring which will heat and fatigue in extremely fast cycling
operations, thus shortening the life of the switch.
The media to be controlled must always be considered when
selecting a pressure switch and, to simplify selection, wetted
materials for each type of switch are noted on applicable catalog
pages.
STEP 2 - PROOF PRESSURES
Choice of the type of pressure switch to be used - diaphragm,
bourdon tube or piston - also must be governed by the proof
pressure to which it will be subjected. (Proof pressure is the
highest surge pressure that will ever be experienced in a system.)
It must be remembered that, although a pressure gauge may
register a constant operating pressure, there may be surges
going through a system that are dampened out by the orifice
in the gauge. Diaphragm and bourdon tube pressure switches
are extremely sensitive and would be affected by those surges.
Barksdale diaphragm switches are available in an adjustable
range from vacuum to 150 psi with proof pressures to 300 psi.
Barksdale bourdon tube switches are adjustable to 18,000 psi with
proof pressures of 24,000 psi. Barksdale piston switches have an
adjustable range to 12,000 psi with a proof pressure of 20,000 psi.
(3) Dual control pressure switches sense two pressure limits
from a single pressure source and open or close two independent
electrical circuits by means of two snap action electrical switches.
STEP 4 - TYPES OF HOUSING AVAILABLE
Stripped pressure switches are basic Barksdale pressure switch units
without housings. They may be used wherever electrical enclosures
are already available and are favored by original equipment
manufacturers for use in common cabinets. Naturally, stripped
switches may be purchased at a lower cost.
Housed pressure switches are completely enclosed to avoid possible
hazard from loose wires in exposed locations.
Terminal block pressure switches are housed and, in addition, are
equipped with enclosed terminal blocks, thus eliminating the expense
of buying and installing external junction boxes.
Explosion proof pressure switches are designed with heavy housings
built to conform to accepted electrical standards in isolating the units
from explosive atmosphere. All explosion proof models are equipped
with terminal blocks for convenience in wiring.
STEP 5 - SELECTION OF ADJUSTABLE RANGE
The term “working range” defines the pressure range a switch may
see under normal working conditions. This is normally the adjustable
range.
For greatest accuracy, the set point should fall in the upper 65% of
the adjustable range. For the most favorable life factor, the set point
should be in the lower 65% of the adjustable range. Therefore, the
most favorable combination of accuracy and life factor lies in the
middle 30% of the adjustable range (see diagram). This general rule
applies both to diaphragm and bourdon tube pressure switches.

STEP 3 - FUNCTION OF THE SWITCH
The function of the switch is another determining factor in making
a selection. Three types of Barksdale pressure switches, based on
function, are described below:
(1) Single setting pressure switches sense a single pressure
source and open or close a single electrical circuit by means of one
snap action electrical switch.
(2) Pressure difference switches sense a change in
relationship between two variable contained pressures and open
or close a single electrical circuit by means of one snap action
electrical switch.

General Operating, Engineering & Service Data
Steam Service
Only diaphragm and bourdon tube switches are suitable for steam service. Install pressure switch with pressure fitting up; preferably
with two or three 4” to 8” coiling loops in the pressure line to serve as heat exchangers and to form a static water head as buffer to
the steam temperature. Dia-Seal type switches may be used if fittings are stainless steel, polysulfone or nickel-plated.
Chemical Protectors
Many Barksdale pressure switches can be used in conjunction with liquid filled chemical protectors: Contact factory.
1. The DIT, D2T, DIH, D2H, DIX, D2X-H18 or -H18SS switches will have an increase in actuation value (differential) of approximately
50%.
2. If a capillary system is used, a lag time will be introduced unless the pressure change is very gradual.
3. Only capillary-type connections can be furnished on pressure difference type switches.
4. Piston type switches, models 9048, T9048, C9612, 9672, C9622, TC9622, 9653, 9673 and diaphragm switches with proof
pressure ratings of 3 psi and 10 psi (-2 and -3 models) CANNOT be used with chemical protectors. Econ-O-Trols must have
impregnated or polysulfone fittings.
5. Vacuum service greater than 20” hg. (gauge) is not recommended. For greater vacuum, consult factory with all details of the
application given.
Life Expectancy
The same factors governing the life of gauges and other instruments, using bourdon tube or diaphragm sensing elements, apply to
pressure switches.
If with each operating cycle the sensing element must flex over the entire operating range for which it was designed, or whether it
flexes only over a small portion of that range considerably affects the life expectancy of the unit.
The second factor to speed up metal fatigue of the tube or diaphragm is the speed with which it must repeat the flexing cycles.
At normal flexing rate (less than 25 cycles per minute) you may therefore find the following variance in the same type of sensing
element:
At full range flexing up to 1,000,000 cycles depending on thickness of diaphragm. The thinner the material, the longer the life. At
50% of its flexing range up to 3,500,000 cycles (see above). At 10 to 20% of its flexing range up to 5,000,000 cycles (see above).
Corrosive Environments
Barksdale housed and explosion proof pressure switches intended for use in hostile and/or corrosive environments can be painted
with green epoxy paint (color per Federal Standard 595A #24300). The complete switch is painted after assembly and test at
Barksdale. For best results, exposed metal surfaces must be touched up with epoxy paint after installation.

Diaphragm Seals
Diaphragm Seals
Product Overview
Introduction
Diaphragm Seals (or Chemical Seals) use a flexible barrier, or diaphragm, to isolate a pressure sensor (switch or transducer) from
adverse effects of the process fluid.
Diaphragm seals are useful to:

Protect the sensor from the process media (corrosive, abrasive, viscous, crystallizing media, or high process temperature)
Protect the process from the contaminants (sanitary process requiring clean-out, or high purity media).
HOW IT WORKS
A diaphragm seal, when properly mounted to a sensor and filled, will accurately transmit process pressure to the instrument. The
pressure applied by the process media is hydraulically transmitted from the flexible diaphragm, through the fill fluid between the
diaphragm and the instrument, to the pressure element, thus engaging the switch or transducer.

Product Overview
Application Considerations
The following should be considered when choosing a
diaphragm seal:

Process Characteristics: Pressure, temperature,
chemical compatibility, and viscosity.

Seal Mounting: Connection to process (threaded,
flanged, clamped, or remote) and connection to
instrument (usually NPT).

Ambient Characteristics: Temperature, corrosive
atmosphere, etc.

Instrument Considerations: Sufficient fluid
displacement is required to drive instrument through
its full range. This means, for example, you can’t put
an instrument with a large displacement on a seal with
a small displacement. Remote instrument placement
requires a capillary connecting instrument to seal.

Vacuum Considerations: High vacuums (over 25”
Hg) or vacuums with high temperatures require
special fill selection, preparation, and procedures, as
well as careful diaphragm selection.
NOTE
Improper seal selection may result in increased system error,
system failure, and possible damage or injury. Barksdale can
provide application assistance, but final compatibility is the
responsibility of the buyer.
SEAL TYPES
Threaded Off-line Seals:
Threaded off-line and flanged off-line seals are commonly used
in a variety of applications. These have a standard cleanout
feature, allowing removal of the process flange or lower housing
without losing the fill. Mounted on a nipple off the line or using a
standard ANSI flange.
Flush Face Seals:
Designed for low displacement applications where a build-up
of solids across the diaphragm is a concern. Threaded process
connection.
Sanitary Seals:
Designed for food, pharmaceutical and other sanitary
applications. Available to fit most standard piping systems with
“Tri-clamp” connection. Standard fill is food grade glycerin.
Mini-Seals:
Designed for low displacement applications where size or
economy are the primary considerations.
Special Designs:
Barksdale is ready to work with you on any high-performance
diaphragm seal application, (that might exceed the stated limits)
such as high vacuum, high temperature, high sterility, custom
design, high static pressure with a low differential span, or high
vacuum with high temperature.
HOW TO ORDER
Follow the Barksdale switch, transducer or solid state part
number with a slash (/) and then the diaphragm seal part
number.

Applicable Mechanical Switch Products
The following Barksdale pressure switches are approved for use with diaphragm seals.
Barksdale’s electro-mechanical switches use a sensor such as
a diaphragm, dia-seal piston, or bourdon tube which actuates
an electro-mechanical limit switch that opens or closes a circuit.
Mechanical switches do not require any power input to operate,
and thus make excellent fail-safe devices.

NOTE
Adding a diaphragm seal to Barksdale’s pressure instruments
will affect some of the product’s performance and accuracy - the
degree of variability depends on the environmental, installation,
service, and/or measurement methods and conditions. The end
user should determine the final overall product suitability and
acceptability in the specific application.
