Company selling fiber optic hydrogen sensors
Key manufacturers of fiber optic hydrogen sensors include United Fiber Sensing, Somni Solutions, KJT Sensors, and Technica, offering intrinsically safe, high-sensitivity solutions for hydrogen detection.
United Fiber Sensing (UFS)
United Fiber Sensing specializes in fiber optic hydrogen leak detection for industrial applications such as electrolyzers, hydrogen storage tanks, pipelines, and filling stations. Their sensors are intrinsically explosion-safe, fully passive (no electronics at the sensing point), and can detect hydrogen concentrations as low as 0.1% vol H2 with a response time of a few seconds. Multiple sensors can be daisy-chained along a single optical fiber, enabling large-scale monitoring. The sensors are ATEX approved and maintain functionality even after exposure to high hydrogen concentrations .
Somni Solutions
Somni Solutions markets a fiber optic hydrogen leak detector in collaboration with UFS. The sensor uses light-based detection rather than electronics, enhancing intrinsic safety. It is designed for continuous monitoring around hydrogen production, storage, and transport facilities, and can be installed near pipes, valves, and meters. The system is suitable for complex installations where multiple sensors are connected to a single fiber .
KJT Sensors
KJT Sensors offers fiber optic hydrogen sensors that provide real-time, precise monitoring in challenging environments. These sensors are designed to overcome limitations of traditional electrochemical or catalytic sensors, such as susceptibility to interference, maintenance needs, and safety risks in explosive atmospheres. The technology relies on light propagation through optical fibers and specialized sensing materials, making it intrinsically safe and suitable for harsh or hard-to-reach locations .
Technica – T910 Fiber Bragg Grating Sensor
Technica's T910 sensor is a rugged, single-mode fiber-based hydrogen detection sensor using a catalytic combustion detection scheme. It features Fiber Bragg Grating (FBG) sensing elements embedded in hydrogen-responsive materials, protected by stainless steel packaging. The T910 is suitable for single-point or multi-point daisy-chained installations, immune to EMI and lightning, and provides high-resolution, repeatable hydrogen detection within seconds. It is ideal for projects requiring long-term, stable, and precise hydrogen monitoring .
Summary
These manufacturers provide a range of fiber optic hydrogen sensors that are:
- Intrinsically safe for explosive environments
- Capable of low-concentration detection
- Suitable for daisy-chained multi-sensor networks
