Manufacturer: Winters Brand: Winters Model: PFP646

The Winters PFP series pressure gauge with stainless steel 316 wetted parts has a glycerin-filled circular dial enclosed in a stainless steel 304 case and a 1/4" NPT male connection, and measures pressure with a single or dual scale with an accuracy of + or - 1% or 1.5%. The stainless steel 316 wetted parts provide corrosion resistance. The socket for the 2.5" and 4" gauges is one-piece welded for strength. The stainless steel 304 case is corrosion resistant and Ingress Protection certified IP66 for protection against solid objects, including dust or liquids, and is appropriate for outdoor and severe ambient and process conditions. The circular dial comes in 2.5" (63 mm), 4" (100 mm), and 6" (150 mm) diameters and is filled with glycerin for protection against vibration and pulsation. The dial is white aluminum with black and red markings. It has an aluminum, anodized black, pointer, and the lens is polycarbonate for high impact resistance. The pointer for the 4" and 6" gauges is micrometer adjustable for ease of calibration. The gauge measures pressure with either a single scale in psi or Hg. vacuum, or a dual scale of either psi/kPa or Hg. vacuum/kPa. The 2.5" gauge is accurate to + or - 1.5% of full scale value. The 4" and 6" gauge are accurate to + or - 1% over the entire range of the gauge, American Society of Mechanical Engineers (ASME) B40.100 Grade 1A accuracy class. The male connection has a 1/4" NPT (National Pipe Thread) rate and comes with a bottom, lower back, or center back mount. The bourdon tube is drawn seamless stainless steel 316 for additional strength, the movement is stainless steel 304, and the welding is tungsten inert gas (TIG) for strength. The socket gasket, fill plug, and lens ring gasket are all made of nitrile rubber for a tight seal. The over-pressure limit is 30% for pressures up to 600 psi (4,147 kPa) and 15% for pressures over 600 psi (4,147 kPa). The working pressure is a maximum of 75% of full scale value. The operating temperature is -4 to 150 degrees F (-20 to 65 degrees C). ...

Manufacturer: WIKA Instrument Corporation Brand: WIKA Model: 9833247

The WIKA industrial pressure gauge has stainless steel wetted parts, which resist corrosion against chloride samples, and has a circular dial that is enclosed in a stainless steel case that resists corrosion. The gauge measures pressure from 15 pounds per square inch (psi) to 15,000 psi, and is accurate to a variety of percentages across the entire range of the gauge, depending on other standard features, such as dial size. Accuracy ranges are: + or - 2.5 percent of span; + or - 1 percent of span over the entire range of the gauge, or American Society for Mechanical Engineering (ASME) B40.100 Grade 1A accuracy class; or + or - 2/1/2 percent of span over the entire range of the gauge, or ASME Grade A accuracy class. The male connection is available as a lower mount, a lower back mount, or a center mount, and comes with a choice of a 1/8", 1/4", or a 1/2" National Pipe Thread (NPT) rate. This pressure gauge is suitable for use in corrosive environments.Pressure gauges are instruments used to measure the pressure of a gas or liquid inside a vessel and, often, to help ensure the optimal amount of pressure for a given application. Pressure gauges can range from everyday instruments, such as those used to measure the air pressure in a car or bicycle tire, to highly accurate gauges used in mechanical and industrial processing. Most often, pressure gauges measure pressure relative to another reference. For instance, gauge pressure measures pressure relative to ambient air. An example of a pressure gauge measuring relative to ambient air is a tire pressure gauge or a blood pressure gauge. Differential pressure is the difference in pressure between two points, such as when measuring liquid flow along various points in a pipeline. An absolute pressure gauge measures pressure relative to a perfect vacuum, such as an atmospheric or barometric pressure gauge. All types of pressure gauges include either a male or a female mount to connect to the vessel where pressure is being measured, and display results on a dial with varying...

Manufacturer: Dwyer Instruments, Inc. Brand: Dwyer

The Original Dwyer® Magnehelic® gage for high accuracy - guaranteed within 2% of full scale - and for the wide choice of 81 models available to suit your needs precisely. Using Dwyer's simple, frictionless Magnehelic® gage movement, it quickly indicates low air or non-corrosive gas pressures - either positive, negative (vacuum) or differential. The design resists shock, vibration and over-pressures. No manometer fluid to evaporate, freeze or cause toxic or leveling problems. It's inexpensive, too. The Magnehelic® gage is the industry standard to measure fan and blower pressures, filter resistance, air velocity, furnace draft, pressure drop across orifice plates, liquid levels with bubbler systems and pressures in fluid amplifier or fluidic systems. It also checks gas-air ratio controls and automatic valves, and monitors blood and respiratory pressures in medical care equipment. (Standard model shown in picture.)

Photohelic Switch/Gages function as versatile, highly repeatable pressure switches combined with a precise pressure gage employing the time-proven Magnehelic gage design. The Photohelic switch/gage measures and controls positive, negative or differential pressures of air and compatible gases. Standard models are rated to 25 psig (1.7 bar) with options to 35 (2.4) or 80 (5.5 bar) psig. Single pressure 36000S models measure to 6000 psig (413 bar) with a 9000 psig (620 bar) rating. Two phototransistor actuated, DPDT relays are included for low/high limit control. Easy to adjust set point indicators are controlled by knobs located on the gage face. Individual set point deadband is one pointer width - less than 1% of full scale. Set points can be interlocked to provide variable deadband - ideal for control of fans, dampers, etc. Gage reading is continuous and unaffected by switch operation, even during loss of electrical power. Choose from full scale pressure ranges from a low 0-.25" (0-6 mm) WC up to 30 psi (21 bar); single positive pressure to 6000 psig (413 bar). Photohelic Sensing - How It Works in typical applications, these Dwyer switch/gages control between high and low pressure set points. When pressure changes, reaching either set point pressure, the infrared light to the limiting phototransistor is cut off by the helix-driven light shutter. The resulting phototransistor signal is electronically amplified to actuate its DPDT slave relay and switching occurs. Dead band between make and break is 1% of full scale or less - just enough to assure positive, chatter-free operation. Relay-Transformer Features. A plastic housing protects all electronic components. Solid-state and integrated circuit electronics are on glass-epoxy printed circuit boards and self-extinguishing terminal boards.
