Quebec City, Quebec, June 11, 2019 – Opsens Inc. (“Opsens” or the “Company”) (TSX:OPS) (OTCQX:OPSSF) today announced that its wholly-owned subsidiary Opsens Solutions Inc. (“Opsens Solutions”), has been granted a patent for an innovative optical-based pressure sensor from the United States Patent and Trademark Office (“USPTO”).

Patent no. 10,082,437 entitled “Optical Pressure Sensor with Reduced Mechanical Stresses” describes an innovative fiber optic pressure sensor design aimed at solving sensor drift, one of the most challenging problems encountered with sensors used in high pressure environments.  Tested by a world-renowned, independent laboratory, this new fiber optic pressure sensor has shown unparalleled low-drift performances when measuring minute changes in differential pressure. This sensor is entirely optical based, without any electronic or electrical components or wires, a feature that makes it particularly attractive for applications in aeronautics and aerospace.

“This sensor is receiving a lot of attention from various industries, especially from aeronautics and aerospace, and more specifically for aircraft fuel monitoring applications, as it is 100% optical, totally immune to electromagnetic interferences and outstandingly precise. Another generation of this sensor is already under development to measure other aircraft fuel parameters, such as temperature and fuel contaminants like water”, said Gaétan Duplain, President of Opsens Solutions.

Opsens Solutions is also proud to announce that it will be exhibiting its fiber-optic sensing solutions at the SIAE Le Bourget 2019, the International Paris Airshow, in France.
