1/4 npt pressure gauges

The Series 4000 Capsuhelic® Differential Pressure Gage is designed to give fast, accurate indication of differential pressures. The gage may be used as a readout device when measuring flowing fluids, pressure drop across filters, liquid levels in storage tanks and many other applications involving pressure, vacuum or differential pressure. The pressure being measured is held within a capsule which is an integral part of the gage. This containment of the pressure permits the use of the gage on system pressures of up to 500 psig, even when differentials to be read are less than 0.1 in w.c.

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.

Our Series LPG4 2.5″ Low Pressure Gage offers top of the line performance and accuracy for pressure and vacuum applications up to and including 160 in w.c. The LPG4 is constructed from a single beryllium-copper diaphragm affixed to a precision-machined brass plate. This innovative design, together with a high-precision, milled-teeth brass movement and nickel-silver pinion and bearing surface, provide the user with a top of the line low pressure instrument.

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 SGZ Industrial Pressure Gages have dual psi and bar (x100 kPa) scales with ±1.5% full-scale accuracy. The Series SGZ gages are designed with 304 SS housings and 316 SS wetted parts for excellent chemical compatibility. These gages cover a wide variety of ranges in either bottom or back connection configurations. Series SGZ 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 TRI2 Tridicator Gage combines the value of an individual pressure gage and thermometer in one instrument. These tridicators simplify installation which reduces time and saves money. The moveable dial with blue pressure markings and red temperature markings make the instrument easy to read. Pressure is indicated in both psi and kPa, while temperature is measured in both Fahrenheit and Celsius. Series TRI2 comes in three different connection options including lower mount, center back mount, and center back mount with extension shank.

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.

The Series DPG-200 Digital Pressure Gage has a precise ±0.25% full scale accuracy. The 4 digit digital display will reduce the potential for errors in readings by eliminating parallax error commonly produced with analog gages. The DPG-200 is packaged in a durable extruded aluminum case designed to meet NEMA 4X (IP66). The unit is powered by 12-24 VDC/VAC and contains two alarm set points along with a 4-20 mA process output. A four-button keypad allows easy access to features. These features include backlight, peak and valley, auto zero and conversion of the pressure units.

The Series DPG Digital Pressure Gages have a high ±0.25% or ±0.5% full-scale accuracy. The 4 digit digital display will reduce the potential for errors in readings by eliminating parallax error commonly produced with analog gages. Series DPG is battery powered and has an auto-shut off to conserve battery life. Battery life, on average, will last 2000 hours. A 4 button key pad allows easy access to features without the need to work through complex menus or difficult key combinations. These features include backlight, peak and valley, tare or auto zero and conversion of the pressure units.

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.

The TIG welding between the case and the process socket, strengthens the instrument and assures better containment 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.
