Technology Overview

Most modern optical strain sensors are intrinsic fiber-optic sensors, where the fiber itself acts as the sensing element. They are preferred over traditional electrical strain gauges in environments requiring electrical isolation, explosion safety, or resistance to electromagnetic interference . These companies provide both point sensors and distributed sensing cables, allowing for flexible deployment depending on the scale and type of monitoring required . By selecting from these manufacturers, users can access high-precision, durable, and reliable optical strain gauge solutions suitable for a wide range of industrial, civil, and research applications.
