501E series radar level transmitters are intelligent non-contact level measuring instruments with their working frequency of 26GHz & 80GHz, which output 4 - 20 mA analog signals. Their maximum measuring range is 120 meters. The antenna has been further optimized, and the new fast microprocessor can perform higher-speed signal analysis and processing, so that the instrument can be used for level measurement of other very complex conditions, such as different kinds of process storage tanks, reactors (reaction kettle) and solid silos, etc.
Advantages
Noncontact measurement, no wear, no contamination;
The antenna size is small, and easy to be installed;
Shorter wavelength, better reflection on inclined solid surfaces;
The upper dead zone is smaller, and they are more suitable even for the level measurement in small storage tanks;
The beam angle is small and the energy is concentrated, which not only enhances the echo capability, but also helps to avoid interference from a possible obstacle;
Almost unaffected by corrosive vapors and foam;
Almost unaffected by changes of water vapor, temperature, and pressure in the atmosphere;
The instrument in severe dust environment can also accurately read the real echoes from the actual level;
Having high signaltonoise ratio, can keep better performance even under fluctuating conditions;
80GHz frequency radar level transmitter is the best choice for measuring solid level and low dielectric constant liquid level. Be suitable for the level measurements of those measured mediums which dielectric constants are respectively ≥1.8.
