Switch/Gage </strong> combine the functions of a precise, highly repeatable differential pressure switch with a large easy-to-read analog pressure gage employing the durable, time-proven Magnehelic? gage design. Switch setting is easy to adjust with large external knobs on the gage face. Gage reading is unaffected by switch operation - will indicate accurately even if power is interrupted. Solid state design now results in greatly reduced size and weight. Units can be flush mounted in 4-13/16" hole or surface mounted with hardware supplied. For applications requiring high cycle rates, choose 3000MRS models with SPST (N.O.) solid state relays. Model provide both low and high limit control and include 18-inch cable assemblies for electrical connections. </p> <p>Gage accuracy is ?2% of full scale and switch repeatability is ?1%. Switch deadband is one pointer width - less than 1% of full scale. Compatible with air and other non-combustible, non-corrosive gases, they can be used in systems with pressures to 25 psig. </p> <p><strong>Applications </strong> </p> <ul><li>Fan Control </li> <li>Damper Control </li> <li>Environmental Pollution Control </li> </ul> <p><strong>Approvals </strong> </p> <ul><li>CE Approval </li> <li>GOST-R Certificate </li> </ul>
