OPP-M Fiber Optic Pressure Sensor

For devices that require miniature sensors

About the OPP-M Fiber Optic Pressure Sensor

The OPP-M is a MEMS-based fiber optic pressure sensor and perfectly suited for industrial applications.

This sensor has a small outer diameter of 0.25mm allowing integration in monitoring devices which have a need for miniature sensors.

Encapsulation can be done on the sensor tip or throughout the whole optical cable. Different materials and sizes are customizable to suit specific OEM applications.

Combined with our WLPI signal conditioning, the OPP-M offers long term accuracy, repeatability, low drift and high fidelity pressure measurements under the presence of harsh EM, RF, MR and microwave fields.
