Fiji Opsens Fiber Optic Sensor

The Fiji Opsens Fiber Optic Sensor is a high-precision, robust optical sensor designed for temperature, pressure, and strain measurements in harsh industrial, medical, and research environments.

Overview

The Fiji Opsens Fiber Optic Sensor leverages fiber optic technology to provide highly accurate and reliable measurements in environments with strong electromagnetic interference, high temperatures, or aggressive chemicals . It is suitable for applications in oil and gas, life sciences, medical devices, geotechnical monitoring, and industrial process control .

Sensor Types and Technologies

• Temperature Sensors (OTG and OTP series): These sensors use Gallium Arsenide (SCBG) or White Light Interferometry (WLPI) technology to achieve high accuracy (±0.15°C to ±0.3°C) and fast response times (<10 ms). They are compact, with some models as small as 0.120 mm OD, and are designed for focal temperature monitoring in dynamic or high-field MR environments .
• Pressure Sensors (OPP series): These sensors employ interferometric measurement where light guided through the fiber changes path length under pressure, enabling precise real-time readings. They are galvanically isolated, resistant to EMC/RFI interference, and can withstand temperatures up to 200°C and aggressive chemicals, making them ideal for medical, chemical, and oil & gas applications .
• Strain Sensors: Designed for marine, subsea, and offshore environments, these sensors can operate under pressures up to 300 bar and high temperatures. They feature quick-connect installation for rapid deployment and robust cable management .

Key Features

• High Accuracy and Resolution: Temperature sensors offer resolutions down to 0.01°C, while pressure and strain sensors provide precise measurements under extreme conditions .
