Faseroptischer Temperatursensor, Anwendung, characteristics-INNO

Mit der kontinuierlichen Weiterentwicklung der Sensortechnologie, Auch die Nachfrage der Menschen nach Sensorik steigt von Tag zu Tag. Faseroptische Sensoren, die die Bedingungen hoher Empfindlichkeit erfüllen, niedrige Kosten, einfacher Vorbereitungsprozess, und gute Stabilität sind selten. Im Prozess der Wahrnehmung und Erkennung, Empfindlichkeit und Stabilität sind die wesentlichen technischen Einflussfaktoren, Dabei sind Herstellungsprozess und Kosten wichtige Einflussfaktoren in der industriellen Produktion. Sensors that combine these advantages are receiving increasing attention and favor.

Fiber optic sensors are sensors that convert the state of the object being measured into measurable optical signals. Der Anwendungsbereich faseroptischer Sensoren ist sehr breit, involving almost all important fields of national economy and defense, sowie das tägliche Leben der Menschen, especially for safe and effective use in harsh environments. The working principle of fiber optic sensors is to send the incident light beam from the light source into the modulator through an optical fiber. The interaction between the modulator and the external measured parameters changes the optical properties of the light, wie Intensität, Wellenlänge, Frequenz, Phase, Polarisationszustand, usw., becoming the modulated optical signal. It is then sent through the optical fiber to the optoelectronic device and demodulated to obtain the measured parameters.

In the existing technology, there are many methods for temperature detection, and the sensors used mainly include bimetallic temperature sensors, Thermistor-Temperatursensoren, and infrared temperature detection devices. These temperature sensors all have different drawbacks, such as bimetallic temperature sensors being sensitive to electromagnetic radiation and not suitable for electromagnetic scenarios; Thermistor temperature sensors require a current source to be loaded during use, which can generate self heating over time. Thermistor temperature sensors are highly sensitive to self heating, causing self heating errors; Infrared temperature detection devices should be vertically incident on the surface of the object being detected during temperature measurement, which is inconvenient to use in narrow spaces.

Faseroptische Temperatursensoren have a wider range of applications due to their advantages of anti electromagnetic radiation and passive detection. The existing faseroptische Temperatursensoren can be pre embedded in narrow spaces to achieve temperature measurement. For objects without temperature measuring optical fibers, when temperature measurement is required, the optical fiber temperature sensor can also be pushed into the object through a traction device;

Accurate temperature measurement is crucial in engineering application systems such as aerospace, high-power stable lasers, and high-precision CNC machine tools. Fiber optic temperature sensors are mainly used to detect changes in external environmental temperature. Compared with ordinary electrical sensors, fiber optic sensors have no electromagnetic interference, starke Korrosionsbeständigkeit, easy manufacturing, niedrige Kosten, schnelle Reaktion, and high detection sensitivity.
