40 / 50 mm Liquid Filled Gauges
Marsh Instruments liquid filled gauges are designed to perform
in rugged and harsh environmental conditions where pulsation
and vibration is a problem. Liquid filled gauges offer a significant cushioning and dampening effect, reducing pointer flutter
and internal gauge damage. Liquid-filled gauges feature a vent
/ filling plug in the top and can be mounted on a horizontal or
vertical plain. The hermetically sealed construction reduces the
chance of leaks and makes field filling an easy option.

Liquid Filled Gauges
• Brass or Stainless Steel Internals
63 mm Liquid Filled Gauges
Marsh Instruments Liquid Filled Gauges are designed to perform
in rugged applications and harsh environmental conditions
- especially where pulsation and vibration are a problem. Liquid
Filled Gauges offer a significant cushioning and dampening effect, reducing pointer flutter and internal gauge damage; also
lubricating the internals, and reducing corrosion. All stainless
steel Liquid Filled Gauges feature a ventable top fill plug for
pressure relief and ease of venting after installation. The hermetically sealed construction reduces the chance of leaks, and
makes field filling an easy option.
Typical applications include refineries, chemical plants, offshore
platforms, oil rigs, marine applications, general industrial application and OEM processes.

Medical Gauges
Marsh produces a wide range of specialist
pressure and temperature gauges for the
medical equipment industry. These range
from simple standard gauges fitted with
custom dial faces to complete specials
designed for specific applications.
The applications are varied and there are
always new challenges to solve presented
to us but the current and past applications include the following:
• Compound Gauges (pressure and
vacuum) for respirator and critical
care devices
• Supply pressure gauges for the above
and anesthesia machines
• Contents gauges for portable
medical gases
• Gauges for medical gas regulators
and distribution systems
• Pressure gauges for angioplasty pumps
• Ambulance applications
• Suction pumps and controllers
• MRI scanners
• Insulflators
• Autoclave temperature gauges
The Marsh range includes capsule gauges
for high accuracy low pressure and vacuum applications, bourdon tube gauges for
general and high pressure applications,
cleaned gauges and isolated gauges for
speciality/hazardous gases and liquids, bimetallic and vapour pressure gauges with
pockets or capilliaries for temperature
measurement.
Our gauges are available in sizes ranging from 25mm dia to
160mm dia in various accuracies and configurations.
We manufacture them in a wide range of materials including
stainless steel, brass, steel and plastic and can supply dial faces
with special scales and company logo’s
Marsh Bellofram Group also make specialist electronic and
manual gas/air pressure regulators for the medical equipment
market for use in many of the above and other fields as well
as rolling diaphragm seals for medical applications.

Diaphragm Seal Gauges
Description
A diaphragm seal is a separator connected to
either directly or via a capillary tube, to the
pressure gauge to isolate it from the process
fluid. They are also known as chemical seals,
barrier seal or fluid separators.
These are used when; The process fluid can
solidify or crystallize; When the process contains solid matter, or has a high viscosity;
When the process fluid could corrode the measuring element.
Operation
The diaphragm seal consists of an elastic element, [diaphragm] that isolates the process
material from the pressure gauge element,
transmitting the pressure through the compression of the filling medium to the gauge.
Connection
Direct mounting, or remote reading via a capillary tube. [Maximum length 15 metres.]

Diaphragm seals must be connected to the

should be made.

Hygienic Diaphragm Seals
Description
These Hygienic seals are manufactured with a 316
stainless steel body and diaphragm which is flush
welded to meet the needs of the food, dairy, brewing and other industries, that requires no unnecessary contamination from bacteria traps.
The design is free of dead space, making the gauges
easy to clean and hygienic.
Transmission of pressure to the gauge, from the
seal, is from a nontoxic liquid, (approved food oil is
our standard) or silicon fluid. The gauges can be fitted directly or remotely, via a capillary tubing, maximum length 10 metres.

Capsule Gauges
Description
Stainless steel case low range capsule gauge
Models: SSC / CAP
ST/CAP
According to DIN EN 837-3
Nominal sizes: 63, 100, 160 and 250 mm
Accuracy: Class 1,6
Construction
These heavy duty industrial gauges, are manufactured with either a mild steel or aluminum case and
bezel, [black epoxy coated], or with a stainless steel
case and bezel.
General construction is with a brass, bar type movement, fully adjustable, beryllium copper capsule
with brass connection block. Alternatively, for the
more aggressive environment, a stainless steel connection and capsule is available
Operation
Atmospheric is used as the reference pressure.
Changes in the measuring pressure causes the capsule to expand, this expansion is in proportion to the
applied pressure, this is then transmitted to the instrument pointer by means of a fine precision movement. This is then indicated as a deflection on the
gauge dial.
Features
Rugged stainless steel case construction
Bayonet locking case and bezel

Contact Gauges
Description
Stainless steel case electrical contact units
Model EC (magnetic snap action)
Available for bourdon tube & diaphragm gauges,
& gas filled thermometers.
Nominal sizes, 100 & 160 mm
Accuracy: Class 1 (bourdon tube)
Class 1.6 (diaphragm)
Magnetically assisted snap-action, interference
contacts, which open or close a circuit when
actioned by the instrument pointer. By means of
a removable setting key, it is possible to alter the
contact points to any position over the instrument
scale. With a single contact the instrument pointer
meets with the set limit contact, the touching pins
giving the contact. With a double contact, this occurs at two set points. The magnetic attraction of
the contacts can be altered by adjusting the magnet, by means of suitable driver, closer or further
away from the contact pins.
The magnetic attraction and / or release always
involves an interference in comparison with the
set limit values, this is between 1 and 6% of the
full scale value, depending on the intensity of the
magnetic attraction.

Schaffer Diaphragms Gauges
Description
Stainless steel Schaeffer diaphragm gauge Models
ST / SCH
According to BS EN 837-3 Nominal sizes, 100 and
160 mm Accuracy: Class 1,6
Construction
These heavy duty industrial gauges, are manufactured with either an steel case and bezel, [blackepoxy coated], or with a stainless steel case and
bezel.
General construction is with a heavy duty fully
adjustable rotary geared movement, in stainless
steel with an upper flange and block in 304 ST.ST
and a lower process chamber in 316 ST.ST. Mounting connection is either threaded or flanged.
Operation
A convoluted diaphragm is clamped between two
flanges. One side is pressurized by the process fluid,
which deflects the diaphragm in proportion to the
pressure. On the other side, a ball joint is fixed to
the diaphragm and connected to the movement via
a push rod, this transfers the diaphragm deflection
to a pointer on the dial.
Applications
For the measurement of either gas or liquid The
fluids can be corrosive, polluted, or highly viscous.
For the measurement of highly viscous, or crystallizing process fluids, a flange connection is used.
Applications include, Liquid level measurement,
fuel pumps, storage tanks, generators, concrete
filling systems, paint filter presses, irrigation and
sludge pumps, trucks, and sewage removal among
others.
