O products are sold in over 75 countries and are widely used in medical, energy, process control, and R&D applications.

Key Features

High precision and stability: FISO sensors provide accurate, repeatable measurements even over long fiber optic leads. Minimally invasive: Some sensors, like the FOP-M200, have diameters as small as 200 microns, allowing use in delicate or constrained environments. Immunity to interference: Fiber optic technology ensures resistance to radio frequencies, electromagnetic fields, and microwave radiation.

Wide measurement range: Sensors can measure temperature (-40°C to 300°C), pressure, displacement, strain, force, and refractive index. Customizable solutions: FISO can tailor sensors and signal conditioners to specific project requirements, supporting both standard and challenging applications.

Applications

Medical and life sciences: Interventional cardiology, critical care, and women's health, where precise and safe measurements are critical. Energy and industrial monitoring: Distributed temperature sensing (DTS) for high-voltage cables, oil & gas pipelines, LNG tanks, and power transformers. Research and development: Laboratory measurements of refractive index, displacement, strain, pressure, and temperature in controlled experiments.

Advantages Over Traditional SensorsFISO fiber optic sensors offer several benefits compared to conventional solid-state sensors: Intrinsic safety: No risk of sparks or electrical hazards in explosive or sensitive environments. Long-distance measurement: Fiber optic leads can extend several meters without loss of accuracy. Rapid response: Certain models, like the FOT-L-BA, provide fast response times for dynamic measurements.

Durability in harsh conditions: Resistant to extreme temperatures and environmental stress.
