**AP Sensing GmbH** is a developer and manufacturer of distributed [fibre-optic sensing](/source/Fiber-optic_sensor) (DFOS) technology products. It is headquartered in [Böblingen](/source/B%C3%B6blingen), [Germany](/source/Germany).[1] The company was founded in 2007 after spinning off from [Agilent Technologies](/source/Agilent_Technologies). AP Sensing operates in [Asia Pacific](/source/Asia_Pacific), the [Americas](/source/Americas), [Europe](/source/Europe), the [Middle East](/source/Middle_East) and [Africa](/source/Africa). AP Sensing is a member of the [Fiber Optic Sensing Association](/source/Fiber_Optic_Sensing_Association) (FOSA). The technology is used for fire detection in assets (i.e. tunnels, conveyor belts and special hazard buildings) and in power cable-, pipeline-, well & reservoir- and rail-monitoring systems as well as in geo- and hydrological monitoring applications.

## History and leadership

AP Sensing was founded in November 2007 and is based in [Böblingen](/source/B%C3%B6blingen), [Germany](/source/Germany).[1] The company originated as a part of [Hewlett-Packard](/source/Hewlett-Packard), which had begun investing in fibre-optic technology before spinning off [Agilent Technologies](/source/Agilent_Technologies) in 1999. Clemens Pohl, one of the founders of AP Sensing, establishing the fibre-optic sensing business of Agilent before spinning off AP Sensing as a separate business in 2007.[9][10] At its founding, its managing directors were Clemens Pohl and Gerd Koffmane.[1] Clemens Pohl is the CEO,[1] the Director of Operations is Uwe Keppler, and the Business Director is Henrik Hoff.[2] Wieland Hill is director of instruments R&D)[3] and Martin Strohbach is director of software solutions and artificial intelligence.[11]

It is a member of the [Fiber Optic Sensing Association](/source/Fiber_Optic_Sensing_Association) (FOSA),[12] an industry organization that promotes the use of [fibre-optic sensing](/source/Fiber-optic_sensor) technology.[13] Martin Strohbach of AP Sensing was elected to a board seat in 2024.[11] According to *Focus* business magazine, they rank as the best employers in Germany in the electronics industry as of 2025.[14] AP Sensing partners with WeForest, a conservationist group,[15] and [Care International](/source/Care_International).[16]

## Products and implementation

Distributed fibre-optic sensing (DFOS) technology is in use in the Americas,[17] Asia Pacific, Europe, and the Middle East,[18] as well as in Africa.[19]

AP Sensing designed its [Distributed Temperature Sensing](/source/Distributed_Temperature_Sensing) (DTS) technology to monitor assets such as power cables and pipelines over large distances[5] as well as for fire detection in tunnels,[20] industrial conveyor belts and special hazard buildings.

In the [United Kingdom](/source/United_Kingdom), AP Sensing's [Distributed Acoustic Sensing](/source/Distributed_acoustic_sensing)/Vibration Sensing (DAS/DVS) technology is used by the [Department for Transport](/source/Department_for_Transport) to collect data from rail lines in order to boost safety and security.[6][7][8] AP Sensing has worked with the [School of Electronics and Computer Science](/source/School_of_Electronics_and_Computer_Science,_University_of_Southampton) at the [University of Southampton](/source/University_of_Southampton) on the [Sofia Windfarm](/source/Dogger_Bank_Wind_Farm) project.[21] The company has collaborated with the [University of Darmstadt](/source/Technische_Universit%C3%A4t_Darmstadt) and DB Net AG to create the FOSSIL (Fibre Optic Sensing for Safety Integrity Level) 4.0 project. Partially funded by the German [Federal Ministry for Digital and Transport](/source/Federal_Ministry_for_Digital_and_Transport), the project investigates whether FOS-based digital twins can be used to improve railway security.[22][23]

The company operates in [Asia Pacific](/source/Asia_Pacific), the [Americas](/source/Americas), [Europe](/source/Europe), and the [Middle East](/source/Middle_East).[24] Distributed fiber-optic sensing technology can be used for leak detection through DAS and DTS.[25] AP Sensing has a regional office in [Bahrain](/source/Bahrain), and operates throughout the [Middle East](/source/Middle_East).[26] Their Distributed Fibre Optic Sensing is designed to monitor pipeline leaks, and is used by the [Kuwait Oil Company](/source/Kuwait_Oil_Company) and the [Abu Dhabi National Oil Company](/source/Abu_Dhabi_National_Oil_Company). In [Saudi Arabia](/source/Saudi_Arabia), AP Sensing technology used for cable monitoring by the [Saudi Electricity Company](/source/Saudi_Electricity_Company), and water pipeline monitoring and leak detection by the [Saline Water Conversion Corporation](/source/Saline_Water_Conversion_Corporation).[26]

Since 2019, the [Earthquake Research Institute](/source/Earthquake_Research_Institute,_University_of_Tokyo) of the [University of Tokyo](/source/University_of_Tokyo) incorporates an AP Sensing DAS interrogator unit to monitor seismic activity off the coast of [Sanriku](/source/Sanriku).[27] In 2019, AP Sensing was selected by [Energinet](/source/Energinet) to monitor cables at the [Kriegers Flak](/source/Kriegers_Flak_(wind_farm)) offshore wind farm using DTS units.[28] In 2020, [Saudi Aramco](/source/Saudi_Aramco) approved the use of AP Sensing's DFOS technology to detect leaks in oil pipelines.[29]
