描述
1, Product overview
The sensor is a 26G high frequency radar level measuring instrument, with the maximum distance of 70 meters. The antenna is further optimized, and the new fast microprocessor can carry out signal analysis and processing at a higher rate, so that the instrument can be used for some complex measurement conditions such as reactor, solid bin, etc.
1.1 Working principle
The antenna of radar level meter transmits narrow microwave pulse, which is transmitted downward through the antenna. After the microwave touches the surface of the measured medium, it is reflected back and received by the antenna system again. The signal is transmitted to the electronic circuit part and automatically converted into the level signal (because the microwave propagation speed is very fast, the time taken for the electromagnetic wave to reach the target and return to the receiver after reflection is almost instantaneous).
A Range setting
B Low position adjustment
C High adjustment
D Blind area range
The datum plane of measurement is: the bottom surface of thread or the sealing surface of flange.
Note: when using radar level timing, the highest level cannot enter the measurement blind area (shown in Figure d). If entering the blind area, all measurement data and output data are wrong.
