Series 605 Magnehelic® Differential Pressure Indicating Transmitter

Same Size as Standard Magnehelic® Differential Pressure Gage

The SERIES 605 Magnehelic® Indicating Transmitter provides for both visual monitoring and electronic control of very low differential pressure. The Series 605 is ideal for control applications in building HVAC systems where local indication is desired during routine maintenance checks or necessary when trouble shooting the system. The easily read dial gage is complimented by the two-wire, 4-20 mA control signal utilizing the time-proven Dwyer® Magnehelic® gage mechanical design and Series 600 transmitter technology. The two-wire design with terminal strip on the rear simplifies connection in any 4-20 mA control loop powered by a 10-35 VDC supply.

Please see Series AT2605 for ATEX approved.

Product Applications

  • Monitor pressures in ducts, rooms, or total building pressures
  • Filter monitoring
  • Local indication of clean room pressures with process signal sent to control room

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
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.
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.
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.
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
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.
