Model 269
can piercing test vacuum gauge
The Model 269 is a high specification vacuum gauge specifically designed for the estimation of the intensity of vacuum in a food can. Using an ordinary vacuum gauge fitted with a piercer is usually very inaccurate and does not allow for the dilution of the head space vacuum by entry of air at atmosphere from the gauge. Ordinary vacuum gauge therefore always give a lower reading than the vacuum existed in the head space before the can was pierced, and if the head space is small the error is compounded.
This gauge was developed by the British Food Manufacturing Industries Research Association and it overcomes the disabilities in an ingenious manner.
The gauge has one piece Polycarbonate case The standard feature include white Anodised Aluminium dial marked in black finish with Stainless steel black coloured pointer and IP67 protection as defined in EN 60529.

diaphragm seal pressure gauges
Model 254 & 255
diaphragm seal pressure gauges
A Diaphragm or ‘Chemical Seal’ is a mechanical barrier that protects delicate instruments from harsh process fluids such as strong Acids, Alkalis and Slurries. All Chemical Seal units operate in an identical manner: the process medium acts upon a diaphragm the deflection of which is transmitted via the fill medium. This pressure is then displayed or transmitted.
Model 254 and 255 are a flexible range of diaphragm seal Gauges with features Filling Fluid for use in an extensive variety of applications throughout industry to include the most arduous process situations.
Designed for continuous operation on gases or liquids where the pressure element could be become corroded or clogged by the process media. Versions are available to withstand pressure pulsations, vibrations and operation at very high temperatures.
The style and materials of construction are carefully selected to withstand not only the process medium but also the maximum design pressure and temperature for each application.

differential pressure gauges
differential pressure gauge
model 179F / model 180 / model m24
The Model 179 Differential Pressure Gauge Consists essentially of two opposing bourdon tubes, each having its own connection but operating a common pointer that shows the difference between the two pressures.
This DP Gauge is used in applications that require an instrument to measure the difference between two pressures where the system pressure is up to 4 times greater than the differential range.
The Model 180 differential pressure gauges are manufactured with a stainless steel diaphragm as the measuring element,
the strength of which depends on the differential pressure graduation. The element is isolated from the pressure by two Melinex diaphragms so that only clean oil fills the chamber in which the mechanism operates.
This instrument is generally used in applications where the system pressure is very much higher than differential range and can be used for measuring differential pressure in filters , strainers, coolers, pumps, natural gas strainers, orifice plates and venturi tubes.
The M24 range of Differential Pressure Gauges have been designed for applications which require the measurement of low differential pressures whilst accommodating very high static pressures.
Designed around a balanced bellows system, which converts the differential pressure into a rotary movement by way of a torsion tube assembly and mechanical linkages. The entire assembly is liquid filled, producing a hydraulic self lubricating measurement system which allows for full line pressure to be applied to either side of the unit without damage to the device. They are available in two dial sizes, 4″ for Model M24-4 and 6″ for Model M24-6.

pressure gauge options / accessories
Pressure Gauge Syphons
The Syphons are designed to meet the demand for protection of instruments such as pressure gauges, where the application have high temperatures that can cause damage or inaccurate readings due to elevated temperatures. They collect condensate from the high temperature media which prevents direct contact with the pressure elements and dissipates the heat. Suitable for all media resistant to SS316.
Swivel Adaptor
The Budenberg Swivel Adaptor is designed for the ease of design and installation of Pressure Gauges and other instrumentation where positional orientation can be determined on site. They are ideal for connection of Pressure Gauges to Valves, and aids the ease of installation especially of Differential instruments. Suitable for all media that is resistant to 316 St.St. Working temperature is up to 400°C.
Viscous Damped Movement (VDM)
The Budenberg VDM is used to overcome the effects of vibration and pulsation. It is used in place of glycerine filling which increases the weight of the Gauge that puts extra strain on installation. VDM applied damping to the movement mechanism at two key operational points, hence keeps gauge clean. Gauge that are fitted with VDM can be easily calibration than glycerine filled gauges.
Gauge Saver (OVP Valve)
The Budenberg Over range Protection (OVP) Valve or Gauge Saver has been primarily designed to Pressure Gauges or other instruments against over pressure conditions, either designed or accidental due to failure of other systems. The unit can be fitted directly to the instrument to be protected on any clean, non-viscous fluids or gases that are compatible with chosen materials of construction.
Adjustable Snubber
The Budenberg Adjustable Snubber is designed to meet the demand for protection of instruments such as Pressure Gauges, where the applications have rapid pulsations or sudden hydraulic shock loading that can damage them. The level of damping is by the adjustment of the needle valve that restricts the flow and therefore protects the pressure gauge against pulsations. Working temp. is up to 120°C.
Check Valve
The Budenberg Check Valve has been designed to meet the demand from applications where high pressures and arduous duties are standard. The valve permits gases and liquids to flow only in one direction, thus preventing the process flow from reversing. The process flow in the desired direction opens the valve, and during the reverse flow the poppet is forced back into its seat closing the Valve.
