Optical strain gauge simplifies sensor handling

A HBM UK product story
Edited by the Engineeringtalk editorial team Sep 11, 2009

HBM has developed optical strain gauges with a plastic encapsulation that simplifies handling and makes the sensors highly resistant to mechanical damage.

The encapsulation almost completely eliminates the possibility of a fibre break.

The optical K-OP strain gauges are mainly intended for experimental stress analysis work that demands very precise measurements, even with difficult conditions and materials, and that cannot be resolved with standard strain gauges.

Such conditions occur, for example, in continuous vibration tests with high strain loads.

The K-OP strain gauges reach 10 million stress cycles in continuous vibration behaviour with alternating strain of +/-3.000um/m.

The optical strain gauges are also suitable for measurements in hazardous areas and in high current and voltage engineering components.

Several optical strain gauges can be arranged within a glass fibre to reduce installation costs.

In addition, the K-OP strain gauges are provided with a sheet containing all necessary data, such as the gauge factor, for successful strain measurements.

Recording of measurement data and its subsequent evaluation can be simplified with a range of additional components from HBM.

These range from optical strain gauges with the appropriate accessories via interrogators, to HBM's data acquisition software CatmanAP, which includes a special Easyoptics module for optical strain gauges.
