26G NYRD SL Non-contact Intelligent Radar Level Transmitter With High Frequency
The working Principle of 26G NYRD SL Non-contact Intelligent Radar Level Transmitter With High Frequency
The radar level antenna emits narrow microwave pulses, which are transmitted downward through the antenna. After the pulse wave touches the surface of the measured medium, it is reflected back and received by the antenna system again, and the signal is transmitted to the electronic circuit part and automatically converted into a level signal (because the pulse propagation speed is extremely fast, the electromagnetic wave reaches the target and is reflected back to the receiver. The time it takes to go back and forth is almost instantaneous)
Datum of measurement: sealing surface of thread bottom or flange.
Note: When using radar level timing, make sure that the highest material level cannot enter the measurement blind area (the area shown in D in the figure).
Design Features of 26G NYRD SL Non-contact Intelligent Radar Level Transmitter With High Frequency
◎ almost immune to corrosion and foam; Not affected by medium density, temperature and pressure changes.
◎ Shorter wavelength, better reflection on inclined solid surfaces.
◎ The beam Angle is small, the energy is concentrated, which enhances the echo ability and is conducive to avoid interference objects.
◎ Measuring blind area is smaller, for small tank measurement will also achieve good results.
◎ High signal-to-noise ratio, even in the case of fluctuations can also obtain better performance.
case of fluctuations can also obtain better performance.
◎ High frequency, is the best choice for measuring solid and low dielectric constant medium.High frequency, is the best choice for measuring solid and low dielectric constant medium.
◎The antenna size is small, easy to install; Non-contact radar, no wear, no pollution.
◎ Serious dust environment has little influence on the work of high frequency level meter.
