Light at the service of hostile environments

Characterize, design, model, calculate, simulate, test, demonstrate this is what sets Phonoptics apart. A lot of professionals have long been looking for a solution to achieve measurements in the most hostile environments, now with sensors designed by Phonoptics it is possible.


Phonoptics develops and markets brand new measurement solutions in hostile environments: temperature and pressure control, vibration measurement and acoustic analysis. But it can also design new sensors on demand to match exact customer expectations. Indeed, Phonoptics has the knowledge and means to be able to develop new custom sensors.


This new patented technology is based on a single optical fiber unlike our competitors who need two. Thus, the sensors are simpler and less expensive and more robust. Finally, our sensors are resistant to high temperatures, 1500 ° C. The microphone is the flagship element at Phonoptics adaptable to all environments, such as:



Pressure sensors for the aeronautical market  

Pressure measurement, monitoring of motors and metal parts.

In addition to this, you need to know more about it.

Key Benefits: EMI / RFI insensitive, withstands temperatures above 150 ° C and -50 ° C, moisture insensitive, miniature and lightweight. We are currently working on new sensors capable of operating up to 1300 ° C.

Microphones for listening and analysis in EMI / RFI environments

This EMC measures the amplitude of a device or an electronic system, to operate in its electromagnetic environment satisfactorily, without itself producing disturbing electromagnetic disturbances.


For pressure measurement, monitoring of pipelines over long distances.

In addition to this, you need to know more about it.

Key advantages: optical fiber of several kilometers, sensor inert to abrasions, withstands high temperatures and pressures, long resistance over time.


The hydrophone for great depths

Continuous listening of the seabed around 4km deep.

In addition to this, you need to know more about it.

Key advantages: today it is impossible for a standard hydrpohone to descend more than a kilometer deep, and under these conditions several repeaters are needed to amplify the signal, the system cannot be connected to the shore directly. .

We allow us to free ourselves from these constraints.


Microphones for the radioactive environment

Microphones allow 24/7 monitoring of noise in a radioactive environment with strong electromagnetic interference.

So this new approach has only advantages:

Specific optical fibers capable of withstanding high temperatures and nuclear radiation over the long term.

In addition to this, you need to know more about it.

Hydrophone for great depths: to allow listening 24 hours a day and 7 days a week at seabed level (around 4 km deep).
