Bourdon tube pressure gauges standard execution DS 1.5”, 2” (40-50mm)
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 “solid-front” pressure gauges HEAVY WORK DS 4”, 6” (100-150mm)

These instruments are designed for use in chemical and petrochemical processing industries, and in conventional power plants.They are built to resist the most severe operating conditions created by the ambient environment and the process medium. The high strength of the sensing element makes these instrument suitable to withstand high overpressure up to 4 times the full scale value and together with the case filling, they are suitable to high dynamic pulsating pressure. An Argonarc welded case/socket strengthens the whole construction. The solid-front version of these instruments is built in accordance with safety specifications of EN 837-1 and ASME B40.1. The safety construction consists of a solid separating wall in stainless steel, placed between the dial and the elastic element and a blow out back which is released from the case whenever an internal pressure, due to leaks, is created or the elastic element is broken.

Safety pressure gauges ”solid-front“ all stainless steel construction for high pressures, DS 4”, 6” (100-150mm)

These instruments are built in conformity with the construction and safety specifications of EN 837-1/S3 e ASME B40.1.
In case of leaks or break of the elastic element, the operator is protected by a solid separating wall placed on the front of the instrument and by the blow out back. They are mainly used on high pressure water jet technology like water cutting machines, hydro blasting pumps and turbines, hydrodemolition. The TIG welding between the case and the process socket, strengthens the instrument and assures a better tight in case of dampening fluid. The advantages of filling the case of the instrument with a dampening fluid are: reduced pointer fluctuation, reduced wear of rotating parts of the movement when pulsant vibrations and pulsations occur.
Moreover condensation and corrosive atmospheres which could damage the internal parts are prevented.

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.

Bourdon tube pressure gauges anti-vibration version DS 4” (100mm)

Instruments designed for use on power units, pump, 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 stainless steel construction DS 4” (100mm)

They are designed for industrial use. They are suitable for tough working conditions and for aggressive fluids. An exclusive Laser calibration procedure features each instrument and allows a very precise accuracy. Filling the case with dampening liquid prevents any condensation and the entrance of corrosive atmosphere increasing its resistance to vibrations and to pulsating pressures.

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.

Bourdon tube pressure gauges NACE MR0103/MR0175 – ISO 15156-3 version DS 4”, 6” (100-150mm)

These instruments are designed for petrochemical industry. They are built to resist to the most severe conditions created by H2S, by the environment and for those fluids, which have high viscosity and do not crystallize. The quality of the materials used to build the sensible element allows their use with high frequency pulsating pressures. The TIG welding between the case and the process socket, strengthens the instrument and assures a better tight in case of dampening fluid.

Using solid state technology, the Series AT-3000MR/MRS ATEX/IECEx Approved Photohelic® Switch/Gage combines the functions of a precise, highly repeatable differential pressure switch with a large easy-to-read analog pressure gage. Gage reading is unaffected by switch operation and will indicate accurately even if power is interrupted. AT102-3000MR series employ versatile electromechanical relays with low amperage ratings-ideal for dry circuits. For applications requiring high cycle rates, choose AT102-3000MRS models with SPST (NO) solid state relays. Easy to adjust set point indicators are controlled by knobs located on the gage face (accessible opening case after de-energizing instrument). All models provide both low and high limit control. Compatible with air and other non-combustible, non-corrosive gases. Flameproof enclosures are available with glass window which allows for viewing of set point needles and process pressure. Compatible with air and other non-combustible, noncorrosive gases.

The Series 765 Process Gage with Dampened Movement minimizes effects of vibration without liquid filling. With this dampened movement the 765 gages are ideal for use in any application where high pulsation or vibration exists. The 765 gages offer dual scale range (psi/kPA) with ±0.5% full-scale accuracy. They are designed with a Phenolic safety-case and have a solid front with a blow-out back. Excellent chemical compatibility is insured with the 316L SS socket and Bourdon tube. A wide offering of ranges are available from full vacuum to 20,000 psi. The 765 process gage comes standard with bottom 1/4″ or 1/2″ male NPT connections.
