OptiMet by HBM™: Optical Fiber with several FBGs in Chain

OptiMet by HBM™ is an optical fiber with high performance coatings and multiple Fiber Bragg Gratings (FBGs) for multipoint measurement of strain.

OptiMet-OMF is optimally suited for use in laboratory applications, whereas the OptiMet-PKF is ideally suited for outdoor use in all kinds of industries.

OptiMet-OMF for laboratory use

The OptiMet-OMF is a singlemode optical fiber with high performance ORMOCER® coating that ensures optimal strain transmission and enhanced stability over an extreme operating temperature range (-269 to 200°C).

It has 13 fiber Bragg gratings equally spaced by 60 cm for multipoint strain measurements. With an outstanding bending capability, it can be installed with bending radii up to 2.5 mm outside the grating area and up to 10 mm inside the grating area.

The OptiMet-OMF is delivered connected to a 1.5m pigtail with an FC/APC connector.

OptiMet-PKF for outdoor use

The OptiMet-PKF is a singlemode optical fiber with high performance ORMOCER® coating with an additional peek layer for ruggedized operation. The coatings ensure optimal strain transmission both to traction and compression directions.

It has 13 fiber Bragg gratings equally spaced by 60 cm for multipoint strain measurements. With an outstanding bending capability, it can be installed with bending radii up to 10 mm.

The OptiMet-PKF is delivered connected to a 1.5m pigtail with 3 mm buffer and an FC/APC connector. Options with only 2 or 4 FBGs are also available as OptiMet-PKF 2 & 4.

The robust OptiMet-PKF is also available in versions with temperature compensation at one (OptiMet-PKF-OTC1) or two (OptiMet-PKF-OTC2) freely selectable measuring positions in the strain gauge chain. This enables thermal influences on the measuring point to be systematically eliminated so that the remaining strain signal is purely mechanical.
