How to detect food temperature changes in microwaves using FISO fiber optic sensors

The MWS Microwave Workstation is designed to perform temperatures measured in a microwave oven equipped with a turntable. Fiber optic sensing technology is completely resistant to microwave energy and provides accurate and reliable measurements in the microwave cavity.

The microwave workstation is equipped with FISOCommander workstation software for complete sensor and results management. Microwave workstations meet the needs of most food developers and testers. With its unique patented technology, the Microwave Workstation provides the absolute accuracy of measuring the absolute cavity length of the FISO Fabry-Perot fiber optic sensor, providing highly accurate and reliable measurements.

The Microwave Workstation is compatible with all FISO fiber optic sensors, including strain, pressure, temperature, displacement, refractive index, force and loading. FISO's fiber optic sensors are fully resistant to RF and microwave radiation with high temperature handling and intrinsic safety. The sensor is also designed to withstand harsh and corrosive environments.

Microwave Work Station enables automatic data collection and seamless data exchange with standard spreadsheet programs such as Microsoft Excel or Lotus 1-2-3. The data includes test sessions for temperature and pressure readings collected during this period. The picture of the sample being tested and the location of the sensor can also be saved in the test file. This valuable information is easily categorized and retrieved at any time for comprehensive data analysis and comparison.

The microwave workstation includes a microwave oven with turntable, a fiber optic rotating device for temperature measurement, FISOComman der Workstation software, all necessary wiring and a comprehensive instruction manual.

The FISO fiber optic sensor uses an interference principle that is ideal for environments where the food industry environment and dielectric sensors are not working. The FISO sensor and its corresponding signal conditioner can form a complete fiber optic sensing system. An interferometric sensor (FPI) generally consists of two opposite mirrors, and the space separating the two mirrors is called the length of the cavity (or void). The light reflected into the FPI is wavelength modulated and is exactly the same length as the cavity. The strain, temperature, displacement or pressure is converted as a function of the length of the cavity by a precisely designed FPI. The principle of the FISO sensor is that when the beam reaches the end of the fiber, it enters a conical medium, causing reflections on the upper and lower surfaces, which in turn cause interference of light. The position at which the reflection occurs is different, and the corresponding optical path difference is also different. When the lateral movement of the chevron medium indicates a change in displacement, this displacement change will be detected and converted by the FP cavity. Because the FISO sensor is completely resistant to electromagnetic, microwave and radio frequency interference, multi-channel online real-time detection of the differences and changes in the temperature of the food in the microwave provides reliable and accurate data for studying the moisture and content of food at different temperatures. Here, the main fiber optic temperature sensor imported from Canada - FOT-L-BA and fiber optic temperature sensor - FOT-L-SD, these two fiber optic temperature sensors are very suitable for measuring temperature in extreme environments, this extreme The environment includes low temperature, nuclear environment, microwave and high intensity RF. The FOT-L combines all the great features you'd expect from an ideal sensor body. Therefore, such sensors provide high accuracy and reliable temperature measurement even under extreme temperatures and adverse conditions.
