Strain gages – just set up and go

The latest improvement to HBM’s modular design of strain gages is the inclusion of an RJ11 plug module to provide maximum flexibility because the installation is simplified and measurements can be taken immediately. Once the strain gage is fitted all that is needed is to connect the RJ11 plug to the amplifier or a distributor board for measurements to begin.

HBM’s modular design comprises various strain gages and different cable types ranging from 0.5 m to 10 m meeting strain gage users’ requirements for ready availability and a wide range of different SG types. HBM provides a wide range of strain gage (SG) types for many applications in experimental stress analysis.

Strain gages with plugs are available in 4-wire configuration, which is necessary when using the Expanded Kreuzer Circuit. This circuit automatically compensates any resistance changes in the connection cables or connectors and thus enables strain gages to be connected without signal loss regardless of long distances between the amplifier and strain gage. No signal variations occur with this circuit even when the plug is connected and disconnected several times.
