  • Description
  • 3000MR models employ versatile electromechanical relays with gold over silver contacts - ideal for dry circuits

    Applications Fan Control Damper Control Environmental Pollution Control

    Compatible with air and other non-combustible, non-corrosive gases, they can be used in systems with pressures to 25 psig

    For applications requiring high cycle rates, choose 3000MRS models with SPST N.O. solid state relays

    Gage accuracy is 177 2 of full scale and switch repeatability is 177 1

    Gage reading is unaffected by switch operation - will indicate accurately even if power is interrupted

    Model provide both low and high limit control and include 18-inch cable assemblies for electrical connections

    Solid state design now results in greatly reduced size and weight

    Switch deadband is one pointer width - less than 1 of full scale

    Switch setting is easy to adjust with large external knobs on the gage face

    Units can be flush mounted in 4-13/16 hole or surface mounted with hardware supplied
