Brand: Dwyer Instruments, LLC
Does not ship to OH, United States
Low cost and precision made, the Series A1F Pressure Switch is ideal for OEM industrial applications.

Wetted materials of 316 Stainless Steel and fluorocarbon ensure great chemical compatibility with a wide range of process media. 

The open case style is perfect for panel mounting applications like pump skids. Weatherproof enclosure is available in polycarbonate offering a low cost weatherproof switch.

Superior 15 A contact allows direct control of motors or pumps without the use of external relays, a true cost saver. Features include a convenient indicating scale for quick and easy field adjustment.
Features
  • 15 A contact allows direct control reducing costs and reliability by having to introduce additional contacts and relays
  • Case style allows use for panel mounting application with optional weather-proof enclosure for use in outdoor environments
  • Field adjustable reduces installation time bring application on-line faster
  • Wetted material provides support for wider range of process media
