Direct Mount Temperature Swichgage® - Without Thermowell (100-500° F)

100-500� F. Without Thermowell. The SDB Series are direct-mounting Temperature Swichgage devices. They provide an accurate direct-reading gauge with an adjustable limit switch to activate alarms and/or shutdown. A knob on 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 SDB touches the adjustable contact, a one-wire-to-ground circuit is completed to shut down the equipment and/or actuate audible or visual alarms. When the temperature rises to the preset trip point, the pointer engages an internal SPDT snap-switch to close/open circuits. The most common use of the SDB Series is to monitor gas compressor temperatures. Engine exhaust temperature can also be monitored to indicate overloading or lean fuel mixtures; or use the SDB to help coordinate loads on twin-engine installations.
