Description:

osc3100The封装structure design of fiber Bragg grating strain gauges simplifies the use of fiber optic sensors, allowing for quick installation and reusability.osc3100Strain gauges are based on fiber Bragg grating sensing technology, with the gratings mounted on a stainless steel substrate material in a pre-tensioned state.osc3100The strain gauge with a grating utilizes glueless packaging technology, ensuring the long-term reliability of the sensor.

osc3100There are two types of strain gauges available: one for spot welding installation and another for adhesive installation. The installation process takes only a few minutes. The spot-welded strain gauge is ready for use immediately after installation, while the adhesive strain gauge typically requires curing at room temperature for less than 24 hours.24Can be used after several hours, similar to a resistive strain gauge.

Comparative tests with strain gauge resistors have shown that,osc3100The strain gauge has the same sensitivity and accuracy as the strain gauge sheet, butosc3100The strain gauge has a larger strain range, while its fatigue life is comparable to that of the resistive strain gauge.100Multiple.osc3100The strain gauge is suitable for use in various harsh environments, offering the inherent advantages of fiber Bragg grating sensors.

osc3100Strain gauges can be used individually or in series with other types of grating sensors. The installation of a multi-point grating sensor string and fiber optic termination is both simpler and more economical compared to traditional multi-point electrical sensors.
