Agilent & AP Sensing

Digitization is the driver for quality, capacity and efficient railway operation for DB Netz AG. Fiber Optic Sensing is an outstanding technology that enables the improval of infrastructure capabilities at lightspeed compared to other solutions using existing cable infrastructure. AP Sensing is taking FOS-based railway monitoring to the next level with their true phase-based system and the extensive use of AI. We’re happy to work in collaboration with AP Sensing’s responsive and innovative team, helping us to get projects moving and getting FOS integrated in the daily railway operation.

Max Schubert

DB Netz AG

AP Sensing's support team has been a fantastic resource for us over the years. They have helped us with system development and implementation planning, and they are always quick to respond to our technical queries with competent advice and helpful tips.

Geoff Harris

Ausgrid

When I think of AP Sensing the first thing I think of is reliability. We completely trust and rely on their performance specifications and I know that their technical support team is dedicated and passionate about solving any problems that might come up.

Paul Sanders

Petrospec Engineering

Knowing the technology and market, it is evident to me that AP Sensing is the forerunner in distributed optical sensing. Their solutions reflect a combination of experience and creativity. Experience comes from their HP/Agilent heritage, the leader in test and measurement equipment, with decades of experience in developing and manufacturing extremely reliable and high quality products. The creativity comes from their passion and commitment to solving real customer problems.

David Orr

Protex Systems

When you do business with AP Sensing you get the feeling that you are working together as partners, because they listen to you and understand the challenges of your day-to-day operations. Communication with AP Sensing is always professional and it's obvious that they have the experience and the technical know-how to answer our queries.

Marcin Cichy

Honeywell

AP Sensing's DTS is simply the best fit. We apply it together with ConveySafe in our coal power plants to protect our conveyors. The systems are rugged and completely reliable, need very little power, and can be seamlessly integrated into customer SCADA environments. Best of all, you don't just buy a box from them and that's it -- their post-sales support is outstanding.

Harald Grzybeck

STEAG

The SIL-2 (Safety Integrity Level) rating that AP Sensing has achieved on its DTS gives us the confidence that their solution is going to work as planned, day in and day out, in high-risk environments. Our LNG terminal operators sleep better at night knowing that our assets are protected and security standards are met.

Dr. Stephan Grosswig

GESO

My AP Sensing regional customer support is fantastic: competent, thorough and quick to get back to me. They have been a key player in our complex pipeline projects over the years, and they truly offer through-life product support, from installation and commissioning to training.

AP SENSING OFFERS COMPLEMENTARY SENSING TECHNOLOGIES

for various markets and specific requirements

LHD

A Linear Heat Detection (LHD) system uses a fiber optic sensor cable to measure the temperature at every point along the entire cable, detecting changes in temperature and hotspots along an entire asset. This technology detects hotspots and fires, alarming quickly and providing precise information on fire location, size and spread.
More …

DTS

DTS (Distributed Temperature Sensing) measures the temperature along an optical fiber, every meter, over many kilometers. This results in an accurate and continuous temperature profile along the sensor cable (1000 temperature points per kilometer).
More...

DAS and DVS

DAS (Distributed Acoustic Sensing) and DVS (Distributed Vibration Sensing) systems detect vibrations and capture acoustic energy along the optical fiber. The fiber functions as if there were thousands of microphones installed. Classification algorithms are used to detect and locate, for example, intrusion activities.

SmartVision

SmartVision is a powerful visualization platform, developed by AP Sensing specifically for distributed sensing technology. With its high-performance database and strong graphical capabilities it is the ideal tool to visualize and analyze events and alarms within large infrastructures.
More...

SmartAlarm

SmartAlarm is a powerful and proven set of simple and advanced alarm algorithms, which are crucial to enable a high probability of detection and low false alarm rates. This enables early fire detection, detection of small leaks, and TPI (third party interference) localization and classification.
