Leading the Way with Passion.

What we do

AP Sensing offers distributed optical sensing technology (DTS - distributed temperature sensing) for a wide range of applications. Based on our HP/Agilent heritage, with over 25 years of optical measurement expertise, we stand for top quality and well-designed solutions. Click on your application area below to see what we can do for you: 

Fire Detection

Security systems demand highly reliable and extremely quick fire detection. You need a solution that is immune to adverse and hazardous environments. Fiber-based linear heat detection is especially suitable for fire detection as it leaves no area unmonitored and displays the real-time temperature development and heat transport of the entire area.

Power Cable Monitoring

Distributed temperature sensing solutions provide continuous monitoring of high power cable temperatures, detecting hot spots, delivering operational status, condition assessment and power circuit rating data (RTTR and DCR). This helps operators optimize the transmission and distribution networks, and reduce costs.   more ...

LNG and Pipeline Monitoring

LNG terminals and modern pipelines need to be closely monitored for integrity, leakage detection and risk mitigation. By making use of optical sensing probes, our DTS solutions are non-corrosive and intrinsically safe. Temperature changes are accurately monitored in real time, 24/7.

Whether you transport LNG, ambient liquids, or very hot or cryogenic fluids, read on to learn more about the industry‚Äôs most reliable and completely-certified DTS solution.  more ...

Oil & Gas Reservoir Monitoring

Today's oil and gas reservoir management requires real time, continuous downhole monitoring to optimize the economic and operational performance of the valuable assets. Through this real-time overview of the production and injection dynamics, the reservoir engineer can optimize production and maximize recovery.   more ...

Geo & Hydrology Surveys

With finest temperature resolution over long distances AP Sensing's DTS solutions support environmental research projects in the areas of river stream monitoring, glacier melting observation, and the vertical temperature analysis of lakes. Intelligent solutions support Enhanced Geothermal Response Tests in geothermal wells, seepage monitoring of dykes and dams and leakage detection in geotechnical applications.   more ...

Industrial Applications
