LEADING THE WAY WITH PASSION

AP Sensing offers distributed optical sensing technologies.

Based on our HP/Agilent heritage, with over 35 years of fiber optic measurement leadership, we stand for top quality and well-designed solutions for distributed optical sensing (Distributed Temperature Sensing, Distributed Acoustic Sensing, Distributed Vibration Sensing).

Distributed Temperature Sensing (DTS)

Distributed Temperature Sensing (DTS) uses fiber optic sensor cables, typically over lengths of several kilometers, that function as linear temperature sensors. The result is a continuous temperature profile along the entire length of the sensor cable.

DTS utilizes the Raman effect to measure temperature. An optical laser pulse sent through the fiber results in some scattered light reflecting back to the transmitting end, where the information is analyzed.

 Distributed Acoustic/Vibration Sensing (DAS/DVS)

Distributed Acoustic/Vibrational Sensing systems detect vibrations and capture acoustic energy along optical fibers. Existing fiber optic networks along the asset are utilized and turned into a distributed acoustic sensor, capturing real-time data and helping operators take right actions. Classification algorithms are used to detect and locate events such as leaks, cable faults, intrusion activities, or other abnormal sounds.

 Alarm Management

In many applications such as fire detection, reliable protection can be enabled with simple maximum thresholds, temperature gradients or temperature differences to average. Depending on the environmental conditions and the expected critical thresholds, these parameters can be set and tweaked individually per detection zone to reach maximum fit for the application needs.

OUR PROPRIETARY SMARTALARM™ ALARM MANAGEMENT TECHNOLOGY GOES BEYOND THESE SIMPLE METHODS.

In collaboration with experts in each application field, we have developed unique methods and algorithms to detect, for example, smaller leaks, even in cases where ambient conditions are changing and the leak itself does not generate a large temperature difference.
