The latest improvement to HBM’s modular design of strain gauges 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 gauge 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 gauges and different cable types ranging from 0.5m to 10m meeting strain gauge users’ requirements for ready availability and a wide range of different SG types. HBM provides a wide range of strain gauge (SG) types for many applications in experimental stress analysis.
Strain gauges 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 gauges to be connected without signal loss regardless of long distances between the amplifier and strain gauge. No signal variations occur with this circuit, even when the plug is connected and disconnected several times.
