Radar Level Meter Operating Principle FM wave FMCW radar products (also called millimeter wave radars), because they use millimeter wave bands with a higher frequency than Ku band radars, they are important in remote target detection and strong smoke and dust environments, such as long-distance imaging and multi spectral imaging. Application, and can detect smaller targets than microwave radar and achieve more accurate positioning, with higher resolution and stronger confidentiality. Radar Level Meter Design Features ◎ Very good transient performance: Based on self-developed CMOS millimeter wave radio frequency chip, it realizes a tighter radio frequency architecture and a higher signal-to-noise ratio. ◎ 5GHz working bandwidth, so that the product has higher measurement resolution and measurement accuracy. ◎ Coherence: Dipole oscillation driven by dry current or non-linear difference frequency effect of coherent laser pulse; ◎ Low energy: The millimeter-wave photon energy is only a few millielectron volts, and there will be no X-ray ionization and damage to the substance to be detected, so it is not easy to damage the substance to be detected. ◎Strong penetrability: It has strong penetrating power for non-polar materials. Many non-metal non-polar materials have less absorption of rays in this band, so they can be used to detect the internal structure of materials. For example, ceramics/cardboard/plastic products/foams are transparent to electromagnetic radiation in this band, and can also be used for airport/station safety monitoring, such as detecting machinery/explosives and drugs, or for circuit board welding detection. ◎ Easily absorbed by polar molecules; this band has less scattering in non-uniform materials, and can detect and measure water vapor content. It is also possible to study the material composition or carry out quality control by analyzing their characteristic spectrum. ◎ Large range and small blind area. The maximum range can reach 120m, and the blind zone can reach 8cm. ◎ Small beam angle and small antenna size make it easy to install. It is less affected by the size of the tank body and the interference of obstacles. ◎The wavelength is shorter, and it has better reflection characteristics on the solid surface, so no special universal flange is needed for aiming. ◎ Support remote debugging and remote upgrade to facilitate the maintenance work of on-site personnel. As an 80GHz band radar used in industrial measurement, it has high-precision, non-contact level and liquid level measurement. It has the incomparable advantages of other ordinary microwave pulse radars and guided wave radars. The extremely narrow beam and penetrating ability are more effective. Adapt to ultra-complex working conditions without compromising measurement performance.
26GHz NYRD-86 Radar Level Meter The radar level meter NYRD80X series sensor is a 26Hz high-frequency radar level measuring instrument with a maximum measurement distance of 80 meters. The antenna is further optimized, and the new fast microprocessor can perform higher rate signal analysis processing so that the instrument can be used fbr some complex measurement conditions such as reaction kettle, solid storage. Radar Level Meter Technical Parameter Typical application Corrosive liquid etc Transmit frequency 26GHz Accuracy 3mm Range 20m Antenna material PFA (optional) Echo sampling 100 times/s Process temperature -40~130℃ Ambient humidity 0~90% Resolution 1mm Process connection flange Electrical Interface M20×1. 5, ½ " NPT Signal output 4...20mA/HART/RS485/Modbus... Supply power 24V DC 220VAC (optional) Power 3W Explosion-proof grade ExiaⅡCT6(optional) Protection class IP67 ※ Note: Products can be customized according to the specific requirements of users! The radar level meter antenna using PFA material, PFA plastic is a copolymer of a small amount of perfluoropropyl perfluorovinyl ether and polytetrafluoroethylene. The melting cohesiveness is enhanced and the viscosity of the solution is decreased, while the properties are unchanged compared with that of PTFE. The resin can be directly processed by ordinary thermoplastic molding. Suitable for making corrosion-resistant parts, wear resistant parts, sealing parts, insulating parts and medical instrument parts. Radar Level Meter Measuring principle The radar level antenna emits a narrow microwave pulse and transmits it down through the antenna. After the pulse touches the surface of the medium being measured, it is reflected back and accepted by the antenna system again, transmitting the signal to the electronic circuit part automatically converted into a object position signal(because the pulse propagation speed is extremely fast, The time it takes for electromagnetic waves to reach the target and reflect back to the receiver is almost instantaneous.) Radar Level Meter Design features The antenna is small in size and easy to install; Non-contact radar, no wear, no pollution. Almost not affected by corrosion and foam; It is almost unaffected by changes in water vapor, temperature and pressure in the atmosphere. Serious dust environment has little influence on the work of high frequency level meter. Shorter wavelength and better reflection on inclined solid surface. The beam angle is small and the energy is concentrated, which enhances the echo capability and is beneficial to avoiding interfering objects. The blind area of measurement is smaller, and good results can be obtained for small tank measurement. High signal-to-noise ratio enables better performance even under fluctuating conditions. High frequency is the best choice for measuring solid and low dielectric constant media.
