Pyreos has been nominated by AP Sensing for a collaborative effort to develop Spectrail, Network Rail’s R&D portfolio of projects with a view for enabling and supporting R&D for the rail industry: Pyreos’ ezPyro surface mount digital infrared sensors will assist in this endeavour, specifically to connect and enable AP Sensing’ fibre optic system. This low-cost IR sensing platform will detect problems like wheel flats, trespass and cable theft before it can impact passengers. The ultimate goal is to automate train inspections and increase data capture, making rail monitoring easier and increasing the types and quantities of assets that can be monitored. 

Pyreos ezPyro SMD sensors have ultra-low power consumption, high sensitivity, faster response and easy integration, which makes them a useful solution for gas, flame, motion and gesture detection as required in the Spectrail project. It is the digital capabilities of ezPyro that allow the sensors to be easily configured and integrated into the Distributed Acoustic Sensing (DAS) network being rolled out by AP Sensing, in conjunction with the consortium. Here, the digital ezPyro sensor data is transmitted over a fibre-optic cable via acoustic vibrations, in addition to the data detected using a distributed vibration sensing system. Pyreos is enabling a series of new, lower power evaluation kits for this project so that its sensors can be operated by next-generation energy harvesters in the DAS network.

“This project is a great showcase for how our pyroelectric sensing technology can be used in critical applications to analyse and measure substances, detect flames, presence and motion,” said Andrew Wallace, CEO at Pyreos: “We are extremely pleased to be working with AP Sensing on this area of rail monitoring.”
