Pneumatic pressure gauges

The Series PTGD Differential Pressure Piston-Type Gage can be used to measure the pressure drop across filters, strainers, pump performance testing, and heat exchanger pressure drop monitoring. Its simple, rugged design possesses weather and corrosion resistant gage front with a shatter resistant lens. The Series PTGD contains a piston-sensing element which provides different differential pressure ranges with full-scale accuracies of ±2%. Constructed with aluminum or 316SS and available with two 1/4″ female NPT end connections, the Series PTGD provides over-range protection rated to 3000 psig (200 bar) or 6000 psig (400 bar) depending on model. Standard models come with in-line connections. Back or bottom connections are also available.

The Series PFG2 Process Filter Gage is designed for determining the state of an inline filter. The differential pressure indicator determines the pressure drop on either side of a filter through its 1/8″ female NPT pressure connections, and relates the value to one of three zones: clean (green), change (yellow), or dirty (red). The Series PFG2 is perfectly suited for filter applications, line loss, valve drop, and many other differential pressure applications where a simple indicator is needed. The direction of process flow is indicated on the dial, with the arrow pointing to the low pressure port. The PFG2 can be connected in-line through the side process connections, but can also be directly mounted through the outlet/inlet.

The Series SGY Gages have dual psi and bar (x100 kPa) scales with ±1.5% full-scale accuracy. The Series SGY gages are designed with 304 SS housings and brass wetted parts for excellent chemical compatibility. These gages cover a wide variety of ranges from full vacuum to 1,000 psi and are available in both bottom or back connections. Series SGY gages employ an easy-open breather plug on top, which allows liquid filled units to breathe, relieving any built up internal pressures. Plug easily pops open and does not need to be entirely removed or cut like a typical gages’ rubber plug grommet.

The Series UGK Gages have dual psi and bar (x100 kPa) scales with ±1.5% accuracy. The Series UGK gages are designed with brass and phosphor bronze wetted parts, and can withstand ambient temperatures up to 140°F (60°C). A wide variety of ranges are available in this economical gage in either bottom or back connection configurations.

The Series UGJ Utility Gages possess dual psi and bar (x100 kPa) scales with 2.5% accuracy. The 2″ UGJ gages are designed with black steel housings. Wetted parts include a brass socket and phosphor bronze tube. A wide offering of ranges are available from full vacuum to 300 psi.

The Series SG5 Contractor Gages are ideally manufactured for contractors because of their large dial and compact design. Since the gages are lightweight and slim, they are easy to transport. The large 4.5″ scale makes them simple to read. The Series SG5 gages possess psi scales with 1% full-scale accuracy. The gages are made with a stainless steel housing and brass wetted parts. Units can withstand temperatures of -4 to 140°F (-20 to 60°C). These qualities make the SG5 series perfect for contractors and industrial applications. A wide offering of ranges are available from full vacuum to 300 psi.

Bourdon tube pressure gauges anti-vibration version DS 2” (50mm)

Instruments designed for use on power units, pumps, hydro-cleaning machines, presses, engine compressors, turbines, diesel engines, chemical, petrochemical and refrigerating plants and on machines and equipment where pulsating pressures or mechanical vibrations are apparent. They can be used with gaseous or liquid media which do not corrode copper alloy and which do not have high viscosity or do not cristalize.

Bourdon tube pressure gauges anti-vibration version DS 2.5” (63mm)

Instruments designed for use on power units, pump, hydro-cleaning machines, presses, engine compressors, turbines, diesel engines, refrigerating plants and on machines and equipment where pulsating pressures or mechanical vibrations are apparent. They can be used with gaseous or liquid media which do not corrode copper alloy and which do not have high viscosity or do not cristalize.

Bourdon tube pressure gauges anti-vibration heavy duty version DS 4” (100mm) Instruments designed for use on power units, pumps, hydro-cleaning machines, presses, engine compressors, turbines, diesel engines, chemical, petrochemical and refrigerating plants and on machines and equipment where pulsating pressures or mechanical vibrations are apparent. They can be used with gaseous or liquid media which do not corrode copper alloy and which do not have high viscosity or do not cristalize.

Bourdon tube pressure gauges with microswitch, DS 4” (100mm)

These instruments are designed for applications in conventional power stations. They safety control the automatic regulation of hydraulic and pneumatic equipment.

Pressure gauges with electric contacts DS 4” (100mm)

They are used to control the electrical operation of compressors, pumps, presses, hydraulic and pneumatics equipment. The contacts open or close the circuit depending on the position of the indicating pointer and they are adjustable over the whole range. For application on severe working conditions, such as rapid and frequent pressure change, vibration and pulsation, they are manufactured with the case liquid filled. The filling drastically reduces the effect of such factors as well as those caused by a corrosive atmosphere, giving longer life and better performances of the pressure gauge and their electric contacts. They are also available with inductive contacts intrinsecally safe.

Pressure gauges with electric contacts DS 4”, 6” (100-150 mm)

Alarm contacts are accessories with movable contacts in air, which open or close electric circuits depending of the position of the indicating pointer. They are used with Bourdon tube pressure gauges, bellows, diaphragm and thermometers of NUOVA FIMA production, in such way they become pressure and temperature switches: the optimal and sure solution to automatize any kind of equipment.
