Benefit from the many new advantages of measuring with light - without having to abandon the ruggedness and convenience of the classical strain gage.
HBM's optical strain gages are made from fibers of glass with a very small core diameter of no more than 4 to 9 manufacturer of micrometers. In comparison, the diameter of human hair ranges from 60 to 80 micrometers. The fiber core is surrounded by a cladding layer from purest glass with a diameter of 125 micrometers.
HBM patented optical strain gages utilize proven technology, and are easy to work with. There is no difference in the handling of optical or traditional (electrical) types of strain gages. You don't have to learn new skills: Bonding, covering, connecting, etc. are all identical. The patented design protects the fiber and makes configuring your test setup quick and convenient. Benefit from both optical sensor technology and the wide range of accessories for electrical strain gages.
Best of both worlds: HBM's measurement technology enables the simultaneous acquisition of data using both electrical and optical strain gages. The EasyOptics module in HBM's catman®AP software enables you to jointly acquire and analyze data from different types of sensors.

The resistance strain gage remains the most cost effective method of understanding a stress system, by calculating stress from a measured strain.
HBM is Europe's leading manufacturer of strain gages. Our extensive range covers everything from strain gages via measuring transducers to analog and digital professional amplifiers. Since our amplifiers can be connected to a PC, measured values can be further processed and then meaningfully displayed with the aid of operator-friendly analyse software specifically designed for measurement technology. Innovative new products in the field of transducer development, signal conditioning and software are witness to our competence and up-to-date product know-how.
In addition to these standard products, HBM also provides customized solutions for sensor technology and electronics as well as complete systems. Our products and solutions are used in all sectors of industry. Our subsidiary companies and over 60 branch offices and agencies worldwide are responsible for providing expert support for measurement technology solutions on site.

The increased use of fiber composites and the systematic optimization of components presuppose a precise knowledge of the load situation. In many applications, sensor integration is the only way to meet the demand for modern lightweight structures with regard to production control, load monitoring, damage analysis and control signal generation.
HBM’s new LI66 strain gages are directly embedded in the structure during the fiber composite production process. This allows measurements at spots that are no longer accessible after production.
The most obvious feature of the LI66 strain gage is the two vertically attached contact pins, for contacting the strain gage embedded in the material. The measuring leads are only connected to the gold-plated pins after manufacture, outside the structure, which makes all the handling easier.
The LI66 strain gage is of a symmetrical design, with structural strain being applied equally to the measuring grid from both sides. Depending on the requirement, the user can decide whether the pins should be contacted inside the structure or on the outside. Thus, for example, with sandwich structures, the measuring leads or customized electronics can be introduced into the foam core. |
