Pressure Gauges
Pressure gauges in this catalogue are activated by a
responsive metal element which deforms under the
effect of the pressure being measured. The
following British and European Standards form the
basis of the design and manufacture of the ‘Jet
range’ Series of pressure gauges and of these
guidelines. They should also be the source of
reference for additional information:
BS EN 837-1 : 1998
Jet range has a wide selection of gauges and
thermometers, which are used to monitor critical
elements that must be controlled in order to achieve
desired performance. This guide will allow you to
select the most appropriate product to meet a variety
of requirements.
The Jet range encompasses:
Pressure Gauges
Bourdon Tube Pressure Gauges – Dimensions,
Metrology, requirement and testing
- 50mm, 100mm, and 150mm diameters in a variety of
pressure settings

Thermometers
The thermometers in this catalogue have circular
dials and are actuated by a bimetal strip element,
linked to the pointer. The following British and
European Standard forms the basis of the design
and manufacture of the ‘Jet range’ series of
thermometers and of their guidelines. The standard
should also be the source of reference for additional
information:
Altitude and Sprinkler Gauges
- 80mm combined altitude gauge and thermometer
- Altitude gauges up to 40 metres
- Sprinkler gauges are glycerine filled with two
pressure options to choose from

Introduction
Pressure Gauges
Safety
The range of the pressure gauge should be selected such that the maximum working pressure does not exceed 75% of the fullscale value when measuring constant pressure, or, 65% for fluctuating pressure. The criteria for the selection of a gauge are a
function of four factors.
1.
2.
3.
4.
The pressure range (up to 25 bar, or, over 25 bar)
The dial size (less than 100mm, or, 100mm and above)
Whether the gauge is ‘Dry’ or liquid (eg glycerine) filled
The state of the material under pressure (as a liquid, or, as gas or steam)
Storage
Pressure gauges should be kept in dry, clean conditions within a temperature range of -40 to +60°C and should be protected
from impact damage.
Installation
It is advisable to install the gauge with an isolating cock or valve that facilitates removal of the gauge for maintenance or
replacement. On installation a leak tight seal should be achieved. If using sealing materials ensure these do not prevent the
fluids entering the gauge. Gauges should be mounted vertically unless designed (and marked) otherwise. Gauges fitted with a
blow out device must have at least 20mm clearance from any obstacle to permit the blow out device to operate correctly.
Installation should take account of the ambient temperature conditions and should these affect the gauge adversely (eg cause the
medium to freeze within the pressure element, then the gauge should be located remotely. A pressure gauge should not be
installed in contact with fluids whose temperature is outside -30 to +60°C. Under these conditions a syphon should be installed
or a suitably remote location selected, where the temperature conditions are more suitable.
Thermometers
Safety
The 'Jet range' series of pipeline thermometers are supplied, as standard, with solid brass pockets with a process connection of
1
⁄2" BSP. The pockets are produced as an interference fit on the brass stem to ensure a high degree of sensitivity. The thermometers
should not be installed without these, or other pockets.
Storage
Thermometers should be kept in dry, clean conditions within a temperature range of -20 to +60°C and should be protected from
impact damage.
Installation
Thermometers will only measure the temperature experienced by the sensor probe. It is important, to achieve correct readings, that
the probe is fully immersed into the flow of the pipeline or vessel. Correct nominal range and stem lengths must be selected before a
thermometer is installed.
