Dynamic Strainmeters Optional Accessory
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.

This adaptor is intended for temperature measurement by T or K type thermocouple using a DC exciting strainmeter. No external power source is required because the adaptor uses bridge excitation supplied from the strainmeter. It is small-sized and can be directly connected to the connector of a strainmeter, thus saving space for installation.

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.
