The FOP-F125 is the world's smallest pressure sensor. It has been especially designed and tested to fulfill the highest of medical performance requirements.

Its applications range from human body fluid pressure measurements for intervention in hospital critical care units to animal testing in high EMI environments. This product is designed to target high volume application where it will be customized to suit OEM-specifi c needs.

With a diameter of only 125 μm, the FOP-F125 is the smallest pressure sensor commercially available. This ultra-miniature sensor is manufactured directly at the tip of the optical fi ber using patent pending technologies suitable for mass production. This all-glass sensor assembled without the use of any adhesive is fully biocompatible and is suitable for integration in medical devices and in minimally invasive instrumented catheters.
