Dwyer DM-259 Offers
Specifically Designed to Mount in a standard Magnehelic Gauge cutout, this pressure transmitter features a polycarbonate molded housing with integral pressure connections, reducing installation time. In addition, the digital push-button zero and span simplify calibration over typical turn-potentiometers, and a single push-button allows field selection of multiple engineering units.
Features
- Reduced installation time through zero and span controls that provides quick and easy calibration
- Fast and easy setup and calibration with push-button zero and span controls
- Immediate corrective action can be taken by local alerts via the easy-to-read LCD display
- Reduces upgrade installation costs and simplifies field upgrade from a Magnehelic Gauge, as both use the same diameter cutout
Applications
- Differential Pressure Across Filters
- Fan Control
- Static Pressures in Ducts or Buildings
- Room Pressurization Monitoring
