Application Note for Optical Fiber Strain Sensors Ideal for Measuring Metal Deformation
Fiber optic strain sensors are compact, high-precision devices that can measure strain in high-temperature environments and are unaffected by EMI/RFI, making them suitable for measurements in highly corrosive environments. These sensors are used in the monitoring of manufacturing processes employing the "die-casting method" for the production of metal components. Due to their accuracy and high precision, they are ideal for measuring metal strain and are designed to be used in harsh environments, such as metal casting, where they are not affected by EMI. Manufacturers in the United States, among others, are currently implementing FISO's fiber optic strain sensors to successfully reduce costs by monitoring the clamping force of machines during casting. 【Main Equipment Used】 ■FOS: Fiber Optic Strain Gauge ■UMI-4: Signal Conditioner *For more details, please refer to the catalog or feel free to contact us.
