Microwave equipment fluorescence fiber optic temperature measurement system

The advantages of the microwave equipment fiber optic temperature measurement system independently developed by Fuzhou Huaguang Tianrui are obvious. It adopts a direct contact temperature measurement method with the heated substance, which can intuitively obtain the temperature inside the heated substance. It is very suitable for application in the electromagnetic field environment of microwave equipment or RF heating equipment.

Characteristics of Fluorescent Fiber Optic Temperature Measurement System in Microwave Industry

Microwaves belong to ultra-high frequency electromagnetic waves and have strong electromagnetic fields. When using conventional temperature sensors (such as thermocouples, PT100 thermal resistors, etc.) for temperature measurement, temperature probes and wires made of metal materials generate induced currents under high-frequency electromagnetic fields, which seriously interfere with the accuracy and stability of temperature measurement, resulting in temperature value errors or inability to perform stable temperature measurements. Therefore, the fluorescence fiber optic temperature measurement system independently developed by Fuzhou Huaguang Tianrui is an interference free temperature sensor in microwave fields. The microwave fiber optic temperature measurement system utilizes the immunity of fiber optic fluorescence temperature measurement to electromagnetic radiation fields to accurately measure the temperature of objects to be heated inside the microwave cavity in environments with ultra-high frequency, strong electromagnetic fields, and heavy interference; And accurate temperature measurement was achieved through the probe of the fluorescent temperature sensor.

Fiber optic temperature sensors are inherently safe, resistant to strong electromagnetic interference, have good electrical insulation, stable performance, corrosion resistance, and long service life; High temperature measurement accuracy, wide temperature measurement range, and flexible configuration of temperature measurement channels; Easy installation, flexible networking, standardized data transmission, high cost-effectiveness, and stable quality; The preferred product for temperature monitoring of high-frequency and microwave equipment.

Fluorescent fiber optic probe

The fiber optic probe consists of three parts: ST connector, fiber optic cable, and end temperature sensing end. The ST connector is the connection part with the optoelectronic module; Fiber optic cable is the transmission part, with quartz fiber inside. The quartz fiber has a coating and cladding on the outside, and a PTFE protective sleeve on the outermost part; The temperature sensing end contains temperature sensing rare earth materials, which are used to generate optical signals containing temperature information; The overall temperature resistance of the optical fiber is 200 ℃, with an outer diameter of 3mm. The long-term bending radius is 13.2cm. The short-term bending radius is 4.4cm. When the distance between the optical fiber lead and the ground is 0.4m, it can withstand a power frequency voltage of 100KV for 5 minutes.
