Dwyer Instruments 530 Switch
The Dwyer Instruments 530 Switch is a technician-grade air flow switch engineered for precision monitoring in HVAC/R duct work. This vane operated flow switch features a rugged die-cast zinc body and a stainless steel vane designed for durability and long-term sensitivity. It is field adjustable from 400 to 1600 FPM, allowing for precise set-point calibration in various system configurations. The integrated SPDT snap switch provides reliable signaling for low air flow alarms or blower interlocks. Built for a 180 degree temperature limit, it performs consistently in harsh environments. Installation is optimized for a horizontal duct flow orientation on ducts 6 inches or larger, requiring only two screws for a secure mount. Note that this unit is specifically designed for non-combustible gas flow and clean, dry air, as the enclosure is not dust-sealed.
- Precision Adjustment: Easily field-adjustable from 400 to 1600 FPM using an internal hex screw.
- Durable Construction: Features a stainless steel vane and die-cast zinc housing to withstand industrial airflow conditions.
- Versatile Signaling: Equipped with a SPDT switch (Single Pole Double Throw) for normally open or normally closed wiring.
- Streamlined Installation: Designed specifically for horizontal duct flow with a compact footprint.
- High Compatibility: Fits any duct size 6 inches or larger; vane can be trimmed for smaller 6-inch applications.
Common Questions
What is the maximum temperature rating for the Dwyer 530?
The unit is rated for an ambient and media temperature limit of 180°F (82°C).
Can this switch be used in vertical ducting?
No, the 530 model is specifically designed and calibrated for horizontal duct flow mounting to ensure the vane reacts correctly to gravity and airflow.
What type of media is the Dwyer 530 compatible with?
It is designed for use only with air or non-combustible, non-corrosive gases. It should not be used in high-dust environments as the unit is not hermetically sealed.
