Unpowered fibre optic sensors deployed in European environmental projects

October 11, 2017 // By Nick Flaherty
AOMS Technologies has deployed its patented Fibre Optic Sensing technology (AOMS-FOS) for monitoring of soil and groundwater in Europe for the first time.

AOMS-FOS is a fully integrated, electricity-free sensing platform for multi-point sensing of parameters such as temperature, humidity, vibration, pressure, and liquid level in harsh and hazardous environments, hard-to-access locations, and remote areas. The sensors use in-situ thermal remediation technology (ISTR) to create an accurate and high-fidelity map of three-dimensional data in real-time from soil and groundwater.

"AOMS optical sensing platform is the most reliable monitoring solution for harsh environment sensing applications such as ISTR," said Hamid Alemohammad, CEO of AOMS. "AOMS Technologies has helped environmental remediation service providers reduce the capital and operational cost of remediation projects and has enabled them to better comply with the stringent environmental regulatory requirements. The technology has significantly contributed to the efficient removal of contaminants from soil and groundwater in urban and remote areas. As opposed to legacy electronic-based sensors and transducers that have reportedly failed due to the exposure to high temperature, hazardous chemicals (such as NAPL, DNAPL, PCB, VOC), and high-voltage electric fields, AOMS-FOS technology has a proven track record of immunity to all these external factors. Sensor failure leads to the inefficient contamination removal from soil and groundwater and high operational and capital cost in an environmental remediation project."

The technology is compatible with state-of-the-art ISTR technologies including Electric Resistive Heating (ERH), Thermal Conductive Heating (TCH), Steam Enhanced Extraction (SEE), and Gas Thermal Remediation. It can be expanded to other subterranean and ground monitoring applications in geothermal, oil & gas, geotechnical, and environmental industries.

AOMS provides an end-to-end hardware/software solution integrated with the Industrial Internet of Things (IIoT) for harsh environments and hard-to-access locations where conventional electronic sensors fail, lose performance, or cannot be effectively deployed.
