AP SENSING OFFERS COMPLEMENTARY SENSING TECHNOLOGIES
for various markets and specific requirements
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).
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™ 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.
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.
Real Time Thermal Rating (RTTR)
A Real Time Thermal Rating (RTTR or DCR, Dynamic Cable Rating) calculates the conductor temperature of the HV cable and predicts the maximum permissible load under consideration of actual thermal conditions and soil heat capacity.
GeoDTS is an integrated solution to monitor geothermal wells. Capable of performing automated EGRT (Enhanced Geothermal Response Tests). Many geo- and hydrological applications can be addressed the hybrid sensor cable, which contains copper wires for heating.
