Distributed Optical Fiber Vibration Sensors: A Game-Changer Distributed Optical Fiber Vibration Sensors have emerged as a revolutionary technology, transforming the landscape of vibration monitoring and analysis. Unlike traditional single-point sensors, Sensuron’s Distributed Optical Fiber Vibration Sensors offer continuous, real-time measurement along the entire length of an optical fiber, providing unparalleled insights into structural behavior. By […]

Accurate temperature measurement is fundamental across various engineering disciplines. From ensuring the structural integrity of bridges to optimizing the performance of jet engines, precise temperature data plays a critical role in design, operation, and maintenance. However, traditional temperature sensors often have limitations, hindering the ability to obtain a comprehensive understanding of thermal profiles. Let’s explore

Fiber Optic Strain Sensitivity The two direct measurements of all Sensuron interrogators are mechanical strain and temperature. This is due to the inherent sensitivity of the Bragg wavelength, as seen below in the well-known Bragg equation. In the absence of thermal effects, obtaining the strain from the above equation is very straight forward. The temperature

Distributed Fiber Optic Sensing (FOS) systems have an intrinsic advantage over traditional Strain Gauge (SG) technology, namely they are capable of measuring strain along the sensing fiber in multiple locations. Sensuron’s FOS system developed in collaboration with NASA is capable of measuring strain at over 2000 locations along a 13m fiber. A single fiber that

In close collaboration with NASA, Sensuron developed compact fiber optic sensing systems that can provide continuous strain measurements. One major challenge facing the development of prominent nondestructive testing and evaluation (NDE) tools has been a lack of fine spatial resolution from sensors. Sensuron’s advanced fiber optic sensing platforms resolve this issue with spatial resolution down

Sensuron’s fully distributed fiber optic sensing technology enables a paradigm shift to take place in the areas of structural testing and monitoring. One frequently overlooked aspect of this shift is the potential cost savings when compared with the use of traditional sensors. For example, thousands of fiber optic strain gauges can be installed on an

Distributed fiber optic sensing has traditionally been a steep entry price technology to get behind. It has been a common issue for many years that has led many engineers to look for other alternatives when they see the price tag. This has adversely affected the technology’s penetration in the marketplace. Fortunately, Sensuron is pleased to

Due to the time and resource intensive installation process, traditional electrical strain gauges are often deployed in limited numbers. Because of budgetary or schedule constraints, engineers are often forced to determine critical points throughout the structure where individual strain gauges will be installed. This lack of comprehensive coverage creates unforeseen risks that can translate into

Any experienced experimental stress analysis engineer would agree that the quality of a strain gauge installation greatly influences the accuracy of the measurement. Simply put, a strain gauge can only function as intended if the substrate strain is transferred to the gauge properly, which requires comprehensive expertise from the installer. As a matter of fact,
