SDB Series Temperature Gauges
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 instrument allows you to adjust the limit switch trip point. Pointer movement is actuated by a bi-metallic sensing element.
