Temperature Monitoring

Optical Fiber Temperature Sensors


Several technologies of optical fiber temperature sensors are available. Whether you want to achieve temperature measurement single-point or multipoint dispatched continuously, we can offer you a system tailored to your needs and meet your technical and economic constraints.

Fiber optic temperature sensors have the advantage of being non-intrusive (diameter of an optical fiber 125μm, 250µm to 3 mm). The associated control unit can be remote from a few meters to several kilometers, this type of temperature sensor is ideally suited for all highly constrained environments including hazardous areas (ATEX)


Measuring ranges: -200 ° C to + 800 ° C

Level of detail/Resolution: +/- 0.1 ° C

Number of sensors: 1 to 120 sensors per electronic processing unit, individually accessible
