These sensors are for use with Manometers, Magnehelic Gages, Pressure Switches and other Controllers to pick up or sense static pressure drop across air filters and cooling coils, blower input and discharge pressures, etc. The angled tips shown have 4" insertion depth. Each has four radially drilled .040" sensing holes. All except Model A-303 mount in 3/8" hole in duct. For portable use, a magnet holds No. A-303 in place. No. A-305 is used where a very low actuation or sensing point is required on a pressure switch or gage or where response time is critical. No. A-307 and A-308 are suitable for use in low velocity systems or where the need for accuracy is less critical.

The Magnahelic guage 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. The gauge's motion is damped with high-viscosity silicone fluid. The zero adjustment screw is conveniently located in the plastic cover, and is accessible without removing the cover. O-ring seal provides pressure tightness. Rugged design resists shock, vibration, and overpressure. The helix is precision-made from an alloy of high magnetic permeability. Mounted in jeweled bearings, it turns freely, following the maganetic field to move the pointer across the scale. The samarium cobalt magnet is mounted at one end of the range spring and rotates the helix without mechanical linkages. What's Included: Two 1/8" NPT plugs, two 1/8" rubber tubing adapters, and three mounting adapters with screws The industry standard in indicating low air or gas pressures of positive, negative, or differential pressures Large, easy-to-read 4" (102 mm) dial No manometer fluid to evaporate, freeze, or cause toxic or leveling problems

The WIKA industrial pressure gauge has copper alloy wetted parts, which resist corrosion against salty liquids, and a circular dial that is three inches in diameter and enclosed in a forged brass case for increased durability in corrosive environments. The gauge measures pressure from 15 pounds per square inch (psi) to 15,000 psi, and is accurate to + or - 2/1/2 percent of span over the entire range of the gauge, or American Society for Mechanical Engineering (ASME) B40.100 Grade A accuracy class. The male connection is mounted on the lower back of the gauge and has a 1/4" National Pipe Thread (NPT) rate. This pressure gauge is suitable for use with paper machines and hydraulic presses.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 increments of measure across a given range.WIKA Instrument Corporation is a global manufacturer of pressure and temperature measurement instruments, including pressure gauges, diaphragm seals, pressure transmitters, and thermometers, that meet International Organizati...
