The AP Sensing DTS N45-Series provides continuous, spatially resolved temperature monitoring using fiber-optic sensing technology. Raman-based Distributed Temperature Sensing measures temperature profiles along the sensing fiber, enabling operators to identify hotspots, abnormal thermal conditions, and temperature trends across long assets in real time.

The N45-Series combines long measurement range, high spatial resolution, fast measurement times, and long-term operational stability. AP Sensing states a measurement range of up to 70 km, spatial resolution of 0.5 m, and measurement times down to 1 second. Its patented code-correlation concept provides an SNR up to 10 times better than traditional DTS instruments, while the single-receiver design supports stable and reliable temperature measurement.
