Abstract

Temperature measurement is regarded to be straightforward by means of standard electronic sensors, however, it becomes considerably more challenging if the sensor is exposed to strong electromagnetic interference or harsh environmental conditions such as e.g. chemical agents. In some cases, the problem may be solved by remote sensors, as pyrometers, but their application is conditioned by the possibility of the direct object observation, which is often excluded.

In this contribution a solution is presented which allows for the temperature tracking in the fiber optic system which facilitates temperature measurements of distant, subjected to the harsh environment objects by transferring their temperatures to the Peltier module. The idea of the system is to adjust the temperature of the reference FBG (at the measurement stage) to the temperature of the sensor FBG with the use of the Peltier module and thus recover its temperature to have it measured with an arbitrary method.

As all electronic part of the system can be installed far from the harsh environment and the system consists of low-cost optical and electronic components, the idea may be found competitive with other methods of the temperature measurements in onerous applications.
