1.Product overview The 80X series sensor is a 26G high frequency radar level measuring instrument with a maximum measuring distance of up to 80 meters. The antenna is further optimized, and the new type of microprocessor can be used for higher speed signal analysis and processing, so that the instrument can be used in some complex measuring conditions, such as reactor, solid silo and so on. 2.principle The radar level antenna transmits narrower microwave pulses, which are transmitted downwards through the antenna. When the microwave touches the surface of the measured medium, it is reflected back and received again by the antenna system, which transmits the signal to the electronic circuit and automatically converts it into a bit signal (because the microwave propagates very fast, The time it takes for an electromagnetic wave to reach the target and return to the receiver through reflection is almost instantaneous).
