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.
- Related
- 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
- Related
- Question
- Can a standard Magnehelic® gage be used for natural gas or propane service?
- Answer
- No. As the silicone diaphragm will be attacked by these gases. A Buna-N diaphragm should be specified.
- Related
- Question
- What happens when a Magnehelic® gage equipped with the low temperature option is operated below -20 degrees Fahrenheit (-29 degrees Celsius)?
- Answer
- Below that temperature the accuracy of the gage deteriorates beyond our published specification due to stiffening of the diaphragm.
- Related
- Question
- Is National Institute of Standards and Technology traceability available for the Magnehelic® Gage?
- Answer
- No. But Magnehelic® gages can be given a special 6 point calibration check with an NIST traceable master gage and a certificate can be supplied.
- Related
- Question
- How do I hook up my Magnehelic® Gage?
- Answer
- In Bulletin A-27 under operation, it explains how to connect the Magnehelic to the following applications: positive pressure, negative pressure, and differential pressure.

- 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.
- Related
- 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.
- Related
- Question
- What restrictions, if any, are imposed for the Magnehelic® and Photohelic® gages in vacuum service?
- Answer
- In applications involving higher vacuums than 20" Hg, leakage due to gage housing porosity becomes the limiting factor.
