Samba technology

The Samba transducer comprises a sensor element mounted on the tip of an optical fiber. The functional principle is that light passes through the fiber and is reflected in a cavity inside the sensor element. The height of the cavity is relative to the external pressure that the sensor element is being exposed to. When the pressure surrounding the sensor element is changing, the reflected light signal will change. The Samba Control Unit receives the reflected light signal and processes it to a readable pressure value.

The transducer is physically designed as a pressure sensitive optical interferometer according to the Fabry-Perot principle. The sensor element is produced in silicon using microstructure processes originating from the semiconductor industry. The optical fiber is made of glass and has special coatings. The Samba Preclin transducer is an example of a MOMS (Micro Optic Mechanical System) device.

Measurement of the surrounding static or dynamic pressure is possible in both gases and liquids.
