Description
Traditionally radar level transmitter measure in high-temperature application environment, using a nitrogen purging for cooling, but for long-term nitrogen cooling causes water vapor condensation in the antenna structure, the radar cannot measure correctly needs to be cleaned regularly.
ANL-9127HTHP radar system adopts a new thermal bridge design,adopts high-temperature resistant steel photonic crystal structure,prevents heat conduction by thermal resistance, and forms a steep temperature gradient so that the radar electronic chamber always maintains a temperature upper limit of not more than 85 degrees Celsius.
The upper part of the antenna structure of ANL-9127HTHP radar system is composed of photonic crystal fiber (PCF) structure antenna,pressure-resistant crystal structure and closed cavity catheter, and the lower part is composed of heat resistance pipe, which is made of high-temperature steel 310S material, for applications with process temperature exceeding 1800 degrees Celsius, the process connection material needs to be made of tungsten steel.
Photonic crystal fibers (PCF) structure antenna have many peculiar properties. Only one mode transmission can be supported in a wide range of electromagnetic wave bandwidth, the arrangement of pores in the cladding area can greatly affect the mode properties, and the asymmetric arrangement of pores can also produce a large birefringence effect of radar electromagnetic waves, which provides the possibility for us to design high-performance antennas with high pressure strength, and it can withstand 8MPa pressure under static pressure. The figure on the right shows the photonic crystal fiber structure inside the antenna of the ANL-9127HTHP.
Pressure-resistant crystal structure, it is a lens made by quartz sealing process, and its thickness varies depending on the process temperature of the actual application.The closed cavity duct forms a closed air interlayer that increases thermal resistance and is placed on the warmer side to prevent condensation inside. Its heat transfer is the result of the comprehensive action of three heat transfer methods: heat conduction, convection and radiation, and is also related to the radiation performance (blackness, temperature), air layer thickness, position, air-to-air layer thickness, position, air-to-air seal ability, heat flow direction and other factors.
