About the SB-120DG/SB-350DG Bridge Box

The bridge boxes are used for connecting strain gauges in several bridge methods including quarter bridge and half bridge. Fixed resistors for configuring a Wheat stone bridge circuit are inside of the bridge box. For strain gauge based transducers of full bridge configuration, if the transducer is without connector plug on its cable end, it is connected to a dynamic strainmeter using a bridge box by connecting cable wires to the bridge box terminals. The bridge method is determined by the way of connection to the terminals or by the setting of switches depending on the type of bridge box.

These are bridge boxes that allow clamp-type quick connection to a measuring instrument. Since no cable is required between the instrument and the bridge box, the instrument can be placed compactly.
SB120DG-1R2 accommodates quarter bridge 2-wire system, and SB120DG-1R3 accommodates quarter bridge 3-wire system.
