2 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 : 1998 Bourdon Tube Pressure Gauges Dimensions, Metrology, requirement and testing 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 - 50mm, 100mm, and 150mm diameters in a variety of pressure settings BS EN : 1998 Selection and Installation recommendations for pressure gauges.

3 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. The pressure range (up to 25 bar, or, over 25 bar) 2. The dial size (less than 100mm, or, 100mm and above) 3. Whether the gauge is Dry or liquid (eg glycerine) filled 4. 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. 3 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.
