About MAGNEHELIC DIFFERENTIAL PRESSURE INDICATING TRANSMITTER

MAGNEHELIC DIFFERENTIAL PRESSURE INDICATING TRANSMITTER

SERIES 605

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.

FAQs of MAGNEHELIC DIFFERENTIAL PRESSURE INDICATING TRANSMITTER:

Q: How do I install the MAGNEHELIC differential pressure indicating transmitter?

A: The transmitter can be installed either on a surface or a panel using the included mounting brackets and screws. Position it vertically for optimal performance and connect pressure lines to the 1/8 NPT threaded ports using the provided static pressure tips.

Q: What is the correct process for zero adjustment on this device?

A: Zero adjustment can be performed via the external screw on the housing. Set the device to zero by ensuring both pressure ports are open to atmosphere, then turn the adjustment screw until the dial reads zero, ensuring baseline accuracy before placing the unit in service.

Q: When should calibration or adjustment be performed after installation?

A: The transmitter is factory calibrated and ready to use upon delivery. However, recalibration or zero adjustment may be necessary after initial setup, extended use, or if verification against a reference standard shows a deviation.

Q: Where can this transmitter be used within an industrial facility?

A: This transmitter is suitable for monitoring air or non-corrosive gas differential pressure in HVAC systems, clean rooms, filter monitoring, or process control scenarios. Its durable construction and IP54 rating make it appropriate for most dry, indoor industrial environments.

Q: What are the output and electrical connection specifications?

A: It delivers a 420 mA (2-wire) output signal for integration with control or monitoring systems. Electrical connections are made using convenient screw terminals, and a 24 V DC power supply is required.

Q: How does this product benefit industrial operations?

A: By providing real-time, accurate differential pressure readings, it enables proactive maintenance, ensures optimal filter operation, and supports energy-efficient ventilation. The fast response time and factory calibration enhance process reliability and system uptime.

Q: What materials and finishing are used for durability?

A: The unit features a die-cast aluminum case with powder-coated or matt finish, an acrylic full-dome cover for dial protection, and silicone/Buna-N seals for reliability, making it resilient against mechanical stress and moderate environmental exposure.
