Optical strain gauges are becoming increasingly popular. They are as easy to install as classical SGs, are not electromagnetically susceptible and can also be used in highly explosive atmospheres.
But just how does a fibre Bragg grating work? Are there other advantages? What do I have watch out for during installation? How do I compensate for optical losses? How many sensors can be integrated into a fibre?
Our experts answer these and other questions about measuring with light in the current technical article.
Easy to handle: optical SGs in a rugged plastic potting
The new optical SGs available exclusively from HBM are even easier to handle: because the new type of plastic potting provides effective protection to the wafer-thin fiber-optic core.
CANHEADdirect: data acquisition directly at the measuring point for smaller and medium-sized applications.
Transmit measurement data from one to five CANHEAD® modules directly to a PC via CANbus... and at an unbeatably good price per channel. The new CANHEADdirect communication module also makes the CANHEAD® system the first choice for smaller and medium-sized applications in experimental structural and stress analysis. Advantages: data acquisition directly at the measuring point and a drastically simplified measuring setup.
catman®AP: the complete software solution for measurement engineers
In the new Version 3.0, there is a new user interface design for even easier operation and thus faster navigation through the main functions. Additionally: catman®AP also provides numerous new functions. For example, there is a channel check module to automatically check the functionality of the amplifier and the correct connection of the measuring points.
The perfect addition for catman®AP is the EasyOptics module that can be used to simultaneously record and visualize data from electrical and optical strain gages.
