OPP-GF Fiber Optic Pressure Sensors

Specially packaged for spot welding installation

About the OPP-GF Fiber Optic Pressure Sensors

The OPP-GF is a MEMS-based fiber optic pressure sensor and perfectly suited for spot welding installation.

Due to its low and smooth profile it can be used for pressure monitoring in environments where fluid flow and aerodynamic forces should not be perturbed by the presence of the sensor.

This fiber optic pressure sensor provides long term accuracy and durability with a pressure operating range of up to 700kPa. It can used for pressure monitoring of blade turbine surfaces, wind and hydraulic tunnels and penstock pipes. With its stainless steel body it is designed to work in hazardous and corrosive environments.

The OPP-C pressure sensor is compatible with all our WLPI signal conditioners. Of course also this compact and very robust sensor can be customized to your specific requirements, including a cable up to 3 kilometers long. Please contact our engineers to discuss your application and possibilities.
