Features

Easy to read gage through undistorted plastic face permits viewing from far away
Patented design provides quick response to pressure changes means no delay in assessing critical situations
Durable and rugged housing and high-quality components combine to provide longservice life and minimized down-time
High accuracy option is twice as accurate as the standard Magnehelic® gage.
Bezel provides flange for flush mounting in panel.
Clear plastic face is highly resistant to breakage. Provides undistorted viewing of pointer and scale.
Precision litho-printed scale is accurate and easy to read.
Red tipped pointer of heat treated aluminum tubing is easy to see. It is rigidly mounted on the helix shaft.
Pointer stops of molded rubber prevent pointer over-travel without damage.
"Wishbone" assembly provides mounting for helix, helix bearings and pointer shaft.
Jeweled bearings are shock-resistant mounted; provide virtually friction-free motion for helix. Motion damped with high viscosity silicone fluid.
Zero adjustment screw is conveniently located in the plastic cover, and is accessible without removing the cover. O-ring seal provides pressure tightness.
Helix is precision made from an alloy of high magnetic permeability. Mounted in jeweled bearings, it turns freely, following the magnetic field to move the pointer across the scale.
Calibrated range spring is flat spring steel. Small amplitude of motion assures consistency and long life. It reacts to pressure on diaphragm. Live length adjustable for calibration.
Silicone rubber diaphragm with integrally molded O-ring is supported by front and rear plates. It is locked and sealed in position with a sealing plate and retaining ring. Diaphragm motion is restricted to prevent damage due to overpressures.
Die cast aluminum case is precision made and iridite-dipped to withstand 168 hour salt spray corrosion test. Exterior finished in baked dark gray hammerloid. One case size is used for all standard pressure options, and for both surface and flush mounting.
OVERPRESSURE PROTECTION
Blowout plug is comprised of a rubber plug on the rear which functions as a relief valve by unseating and venting the gage interior when over pressure reaches approximately 25 psig (1.7 bar). To provide a free path for pressure relief, there are four spacer pads which maintain 0.023" clearance when gage is surface mounted. Do not obstruct the gap created by these pads. The blowout plug is not used on models above 180" of water pressure, medium or high pressure models, or on gages which require an elastomer other than silicone for the diaphragm. The blowout plug should not be used as a system overpressure control. High supply pressures may still cause the gage to fail due to over pressurization, resulting in property damage or serious injury. Good engineering practices should be utilized to prevent your system from exceeding the ratings of any component.
O-ring seal for cover assures pressure integrity of case.
Samarium Cobalt magnet mounted at one end of range spring rotates helix without mechanical linkages.

Mounting and Orientation
A single case size is used for most models of Magnehelic® gages. They can be flush or surface mounted with standard hardware supplied. Standard gages are calibrated in the vertical position, and should be used in that position for maximum stated accuracy. Ranges above 17.5 in w.c. may be used at any angle, and should stay within specified accuracy, by simply re-zeroing. Ranges below 17.5 in w.c. should be ordered using the –TA tilt angle option with the angle specified. These characteristics make Magnehelic® gages ideal for both stationary and portable applications. A 4-9/16" hole is required for flush panel mounting. Complete mounting and connection fittings, plus instructions, are furnished with each instrument.
AHU1 Furnished with attached surface mounting plate
AHU2 Furnished with attached surface mounting plate and including A-481 installer kit (2 plastic static pressure tips and 7´of PVC tubing)
CB Chrome bezel option: A chrome plated aluminum bezel for an aesthetically pleasing finish when mounting on metal surfaces such as control panels.

FAQ

Questions

Question

How will installation of a Magnehelic® gage 150' away from the pressure source affect accuracy?

Answer

Accuracy will not be affected, but response time will be increased in proportion to the length of the tubing.

Question

Can the standard Magnehelic® or Capsuhelic® gage be installed outdoors?

Answer

Yes. Front covers are sealed with "O" rings. Capsuhelic vent holes are plugged with foam, and the new high impact acrylic lens material is very resistant to ultra-violet fogging. Additional care is recommended to lead pressure connections downward from the gage and provide as much protection from the elements as possible

Question

Your Magnehelic gauge doesn't come with a calibration certificate, do you have any documentation for these gauges to meet these needs?

Answer

We have 3 options: (1) We can supply a Certificate of Conformance at no charge if you request that certificate at the time of order. The Certificate of conformance would state that each Magnehelic gauge is calibrated to meet the specifications stated on the spec sheet. (2) We offer a factory calibration “-FC” as an option that is a certificate of the standard calibration points at the time of manufacture, for a small fee. (3) We can also provide a NIST-traceable calibration for an extra charge per gage if that is required. To get the NIST-traceable calibration, you would simply add a “-NIST” to the end of your part number. NIST-traceable calibrations will come with the 6 point calibration certificate. We recommend “periodic calibration” for our Magnehelic, though we leave the specific time-frame up to the end user, since different organizations have different requirements (i.e. government groups often require more frequent calibrations.) If you choose to have the NIST traceable calibration done, the NIST group (the National Institute of Standards and Technology) dictates yearly calibration and it will be printed on the certificate.

Question: I am looking to measure velocity in a 4" pipe that is used as air conveyance. We use an eductor and a single stage blower to produce air flow. I am looking to measure pressure and velocity. I purchased a Dwyer Pitot tube, 167-7 108024-00 for the job, and I want to match with the right gauge. I need to be in the range of 2600 cuft/min at maybe 0.5psi. Can you direct me to the right gauge with that information?
Answer: To monitor flow through your 4” pipe, you will have to size the appropriate differential pressure gage. A very common gage that is used will be our Series 2000 Magnehelic gage. This gage can be ordered with a square root output that will direct read in flow units. Upon ordering this part, you will have to specify the maximum differential pressure at your desired flow rate. The following text will bring you to the equations necessary to compute this differential (velocity) pressure. This can also be found in the APPLICATION GUIDES section of our website.

Question

I have a Magnehelic gage 2000-00N I purchased for a clean room. Should the installers set the "set" screw to get the gage back to (0) or will that mess up the calibration? My invoice # if you need to look at what I purchased is 04844623.

Answer

After the Magnehelic has been installed, disconnect pressure lines to vent both sides of the gage to the atmosphere and re-zero. This will not mess up the calibration. This should be done occasionally.

Question

How do I hook up my Magnehelic® gage for an air velocity application with a pitot tube?

Answer

In our Application Guides on flow products, we explain very well how to take air velocity readings. The total pressure connection on the pitot tube is connected to one of the high pressure ports on the gage. The other high pressure port is plugged. The static pressure connection on the pitot tube is connected to one of the low pressure ports on the gage. The other low pressure port is plugged.

Question

Are air velocity scales available?

Answer

Yes, the information we require to supply the proper range is the velocity (fpm or m/s) or velocity pressure (inches of water or kpa) and density of air (lb/ft3 or g/cm3).

Question

Why must Dwyer pressure switches be mounted with the diaphragm in the vertical plane?

Answer

In other than a vertical plane, the diaphragm can sag and cause a shift in set-point or a change in the adjustable set-point range. The switch may even fail to reset at the minimum set-points. This is the same phenomena that causes inaccuracy in Magnehelic® and Capsuhelic® gages when mounted in other than a vertical position.

Question

What might be the cause for Magnehelic® gages filling approximately 1/3 full of water, with lots of liquid droplets on the glass. Both are outside mounted on the side of an air stripping tower. One is a differential pressure gage that measures the pressure drop across a pitot tube. The other just measures the back pressure in the stripper. What can be done to fix the malfunction?

Answer

It looks like you’re getting some condensation in the Magnehelic®, which is causing it to collect on the bottom of the face. Since the Magnehelic® is not encapsulated, it is not recommended to be used in applications where moisture can form. One option to fix the problem is installing a liquid filter (like an F222) to filter out that moisture. Another option is to install a Capsuhelic (Series 4000), which is made to handle both air and liquid.

Question

Can the ASF option be used as a tattle tell? Or do you have something that could be used as a tattle tell on the 2000 series DP gages?

Answer

The ASF option cannot be used as a tattle tell. It is just there for visual indication of a set point. We have nothing with our 2000 series that can act as a tattle tell, however our series DM-1000 DigiMag will have a peak valve function built in.

Question

I have a Dwyer Magnehelic, can I pressure test a furnace gas valve with natural gas with this instrument?

Answer

The standard Magnehelic is not recommended for use with natural gas. For natural gas applications, we would recommend a Magnehelic with a Buna-N diaphragm and an oil impregnated case for better chemical compatibility and a reduced leak rate respectively.

Question

Calibration details?

Answer

Standard gages are calibrated in the vertical position, and should be used in that position for maximum stated accuracy. Ranges above 17.5 in w.c. may be used at any angle, and stay within specified accuracy, by simply re-zeroing. Ranges below 17.5 in w.c. should be ordered using the –TA tilt angle option with the angle specified.

Question

What is the best method of measuring actual air flow in process ducts to verify process air flow sensors (differential pressure sensors, air flow stations, etc.)

Answer

There are two ways to measure air flow in process ducts. The most common means is the use of a Series 2000 Magnehelic® Differential Pressure Gage. This gage can be ordered with a square root output that will read in flow units. You will have to specify the maximum differential pressure at your desired flow rate. Along with the gage, a pitot tube (connected by means of rubber or vinyl tubing) is also used. The pitot tube must be pointed directly into the air stream. Care must be taken to ensure that the pitot tube should be inserted at least 8-1/2 duct diameters downstream from elbows, bends or other obstructions which cause turbulence. The alternative method uses a 100 AV Durablock® Air Velocity Gage kit. The kit includes a manometer, a stainless steel pitot tube, rubber tubing with connectors, and red gage fluid. The pitot tube, pointed directly into the air stream, senses total and static pressure. The manometer then senses velocity pressure (difference between total and static pressure).
