Single-point fiber optic sensor solution

Single-point fiber optic sensors are compact, high-precision devices designed for localized measurement of temperature, strain, or other parameters, with series like Opsens OTG/OTP, Keyence FU, and Panasonic FT/FD offering specialized capabilities.Opsens Single-Point SensorsOTG Series: Designed for highly focused temperature monitoring with very short measurement times. These sensors use gallium arsenide semiconductor bandgap (SCBG) technology, feature an outer diameter of 0.12 mm, a response time of less than 10 ms, accuracy of ±0.3°C, and resolution of 0.01°C. They are plug-and-play and suitable for long-term reliability applications .OTP Series: Suitable for simultaneous monitoring of temperature and other parameters. Based on White Light Interferometry (WLPI), they are robust, immune to electromagnetic interference (up to 3 Tesla), and offer excellent accuracy of ±0.15°C with 0.01°C resolution. They use a monocrystalline birefringent crystal to prevent thermal creep and aging .Keyence FU SeriesThe FU Series consists of fiber optic sensor heads connected to an amplifier. They include thru-beam, reflective, retro-reflective, and definite reflective types. These sensors are ideal for factory automation, tight spaces, and harsh environments because the sensing heads contain no electronics. They detect targets by measuring changes in light reflection or transmission .Panasonic Fiber SensorsPanasonic offers ultra-small diameter fibers with compact heads for precision centering and detection of minute objects. Series include FT-KV40H1 (thru-beam) and FD-L13H1 (reflective), capable of operating in extreme temperatures (-60 to +350°C) and chemical environments. They are suitable for narrow installation spaces and high-temperature applications .Sensuron Optical Fiber SensorsSensuron provides high-resolution fiber optic sensing for distributed and single-point measurements. Their systems can monitor strain, temperature, deflection, and 2D shape in real-time. Single-point sensors are integrated into platforms like the GTR and SGTR FBG interrogators, offering 1 pm precision, high-speed sampling, and multi-sensing capabilities .ApplicationsSingle-point fiber optic sensors are widely used in:Industrial automation for detecting small or difficult targets.Temperature monitoring in MR environments, microwave fields, or high electromagnetic interference areas.Structural health monitoring for strain, deflection, and multi-parameter sensing.Harsh or confined environments where conventional electronic sensors cannot operate reliably. These series differ in technology, measurement precision, environmental resistance, and integration options, allowing selection based on specific application requirements. Opsens focuses on high-precision temperature sensing, Keyence on industrial automation detection, Panasonic on compact and heat-resistant solutions, and Sensuron on high-resolution multi-parameter monitoring.
