Measure more, in extreme conditions, leading the way in optical sensor technology for Industrial, Energy, and Aerospace applications. Our optical pressure sensor technology uses super resistant materials such as single-crystal sapphire (melting point >2000C) together with innovative fibre optic interrogation techniques which give high sensitivity and immunity from electro-magnetic interference (EMI) effects. This enables direct pressure and temperature sensing of harsh environment applications including process plant, energy, and aerospace systems. Products validated by the most demanding power generation and aviation customers are adapted for wider application in industrial systems. With two major partnerships Oxsensis in place the market reach is extending. Oxsensis is keen to work with end users, systems integrators, and instrumentation partners to exploit the benefits of optical instrumentation in key applications.
