Product Overview
Low-Range Differential Pressure Gauge with 4–20 mA Output (Unused NOS)
This indicating transmitter combines a mechanical dial with a loop-powered signal for low differential pressure monitoring in air systems. It delivers local visibility and remote reporting from one instrument, simplifying installation. Practical tip: use short, clean impulse lines and stable loop power for consistent in WC / Pa readings.
Product Condition
Unused, New Old Stock. In original packaging without box.
Product Overview
The Magnehelic 605-6 integrates Dwyer’s mechanical gauge movement with a two-wire 4–20 mA transmitter. Configured for a 0–6 inches water column range, it provides simultaneous visual indication and a standard process signal for automation. Dual high/low ports and rear zero/span adjustments support straightforward setup and maintenance.

Frequently Asked Questions
Is this a transmitter or a gauge?
It is both: a mechanical Magnehelic gauge with an integrated 4–20 mA transmitter.
What power is required for the output?
The transmitter is loop powered and operates from a 10–35 VDC supply.
What media can it measure?
It is intended for air and compatible non-combustible gases.
How are adjustments made?
Zero and span are adjusted using protected potentiometers on the rear.
You can add local indication and remote monitoring by mounting this unit on a panel, connecting the 1/8 in NPT ports, and wiring the 4–20 mA loop into a control panel or PLC input.
