The Murphy SDB500-2 is a Direct Mounting Temperature Swichgage device that provides an accurate direct-reading gauge with an adjustable limit switch to activate alarms and/or shutdown. A knob on the front of the Swichgage allows you to adjust the limit switch trip point. Pointer movement is actuated by a bi-metallic sensing element. When the indicating pointer on the SDB500-2 touches the adjustable contact, a one-wire-to-ground circuit is completed to shut down the equipment and/or actuate audible or visual alarms. Proper relays or Tattletale annunciators (magnetic switches) must be incorporated into the system.
A thermowell (separable socket) is used to facilitate maintenance of a temperature Swichgage and to protect the temperature sensing bulb from extreme amounts of system pressure.
Applications: The most common use of the SDB Series is to monitor gas compressor temperatures. Engine exhaust temperature can also be monitored to indicate over-loading or lean fuel mixtures, or use the SDB to help coordinate loads on twin-engine installations.
