Product Overview
CHRD900 series sensors are 26G high frequency radar type level measuring instruments, measuring ZUI distance up to 70 meters. The antenna is further optimized for processing, and the new fast microprocessor can carry out signal analysis and processing at a higher speed rate, which makes the instrument can be used in some complex measurement conditions such as reactor, solid silo and so on.
Principle
The radar level antenna transmits narrow microwave pulses, which are transmitted downward through the antenna. Microwave contact with the surface of the measured medium is reflected back again by the antenna system receives, the signal will be transmitted to the electronic part of the automatic conversion of level signals (because of the microwave propagation speed is extremely fast, the electromagnetic wave reaches the target and by reflection back to the receiver the time used in this back and forth is almost instantaneous).
