Usource, Yokogawa, OSENSA, WEINERT Industries, and COMEM Group are leading manufacturers of high-performance optical cables and fiber optic temperature sensors suitable for precise and fast temperatur...
Usource offers high thermal conductivity distributed temperature measurement optical cables with a thermal conductivity exceeding 1.0 W/m·K. These cables feature an ultra-micro stainless steel tube, double-layer armored protection, and an overall diameter of less than 3 mm, providing fast thermal penetration and rapid temperature response. They are suitable for applications in lithium battery warehouses, electrolytic cells, large buildings, highways, subways, coal mines, and petrochemical pipelines, especially where high response time and high spatial resolution are required .
Yokogawa's DTSX1 fiber optic heat detector uses distributed temperature sensing (DTS) technology, where the fiber itself acts as the sensing element. This system allows thousands of accurate temperature measurements over long distances, making it ideal for fire detection, leak detection, and preventative maintenance in large plants. The optical fiber is immune to electromagnetic interference, providing high-resolution and precise temperature monitoring .
OSENSA provides CSA/UL/Marine certified fiber optic temperature transmitters and probes for industrial applications. Their products are immune to electromagnetic radiation, high voltage, RF, and magnetic fields, and can be paired with polymer or glass optical fibers. OSENSA supports on-premise and cloud monitoring, offering historical trending, alarms, and software for configuration and data logging .
WEINERT Industries specializes in high-temperature optical fibers based on fused silica, optionally equipped with heat-resistant coatings. These fibers can operate in extreme temperature ranges from −190 °C to +385 °C, making them suitable for high-temperature industrial processes and research applications .
COMEM Group manufactures fiber optic sensors using Gallium Arsenide (GaAs) crystals at the fiber tip, providing highly accurate temperature measurements in environments with microwave radiation or high-frequency interference. Their sensors are fully non-metallic, dielectric, and immune to EMI/RFI, suitable for high-voltage, magnetic, and harsh industrial environments. COMEM's solutions offer fast response, small probe size, and customizable semi-rigid designs .
