AP Sensing and Prysmian SensO are key providers of fiber optic temperature-sensing cable systems in Denmark.

AP Sensing

AP Sensing, headquartered in Denmark, specializes in fiber optic sensor cables designed for real-time monitoring of temperature, strain, and acoustic signals in challenging environments . Their sensor cables include various configurations such as metal-tubing, metal-free, tube-in-tube, and armored stainless steel, allowing deployment in harsh industrial conditions. The cables use coatings like polyimide or metal for high-temperature or cryogenic applications, ensuring precise temperature measurements over long distances. AP Sensing systems are widely used in power cable monitoring, fire detection, and industrial process control.

Prysmian SensO

Prysmian, with operations in Denmark, offers the SensO Distributed Temperature Sensing (DTS) cables, which convert optical fibers into continuous temperature sensors . These cables utilize Raman or Brillouin scattering technologies to provide a continuous temperature profile along the cable length. SensO DTS cables are designed for extreme conditions, including fire detection in tunnels, cryogenic monitoring in LNG tanks, and pipeline leak detection, with rapid response and high spatial resolution. The system allows 24/7 monitoring over tens of kilometers with minimal maintenance.

Key Features of Danish Fiber Optic Temperature-Sensing Systems

• Distributed sensing: Continuous temperature measurement along the entire cable length.
• High spatial resolution: Sub-meter or even sub-millimeter resolution for precise monitoring.
• Harsh environment compatibility: Resistant to high/low temperatures, electromagnetic interference, and mechanical stress.
• Versatile applications: Power cable monitoring, industrial process control, fire detection, LNG and pipeline monitoring.
• Passive and safe: Optical fibers are electrical insulators, immune to self-heating, and provide galvanic isolation .

Other Danish Optical Sensor Companies

While AP Sensing and Prysmian SensO are leaders in temperature-sensing optical cables, other Danish companies like ATE Optical and Ibsen Photonics focus on optical sensors and spectrometer modules, which may complement fiber optic sensing systems in industrial or research applications . These Danish manufacturers provide robust, high-precision solutions for distributed temperature monitoring, making them suitable for critical infrastructure, industrial, and safety applications.
