SFO-W Spot-Weldable Strain Sensor
HIGH RESOLUTION
FIBER OPTIC STRAIN GAUGE
INTRINSICALLY SAFE
The SFO-W gauge is designed for long-term, precise strain measurements on a variety of structures. It can be installed on flat or cylindrical surfaces
The SFO-W consists of a small diameter stainless steel tube welded on a steel sheet. It is suitable for spotwelding on steel surfaces.
The sensor is based on a unique fiber optic strain gauge. The Fabry-Perot strain gauge is bonded inside the steel tube, thereby following the tensile or compressive movements of the spot-welded gauge.
The SFO-W gauge is designed to be installed by a technician without the assistance of a skilled welder. The SFO-W gauge is intended for long-term, precise strain measurements on a variety of structures. It can be installed on flat or cylindrical surfaces.
