High Precision Radar Water Level Sensor Price Transmitter Water Level Transmitter
Sensor is 26G High Frequency radar level sensor, measure the maximum distance to 70 meters.
Antenna being further optimized, fast new microprocessor could be higher-speed signals processing, makes the instrument can be used in reactors, solid-state storage bin and some complicated
measuring conditions. Antenna size is small, easy to install; non-contact radar, no abrasion, no pollution. Which is almost not influenced by corrosion and foam. And virtually unaffected by water vapor, temperature and pressure changes in the atmosphere. Serious dust environment has little effect on high frequency level meter. Shorter wavelength, and has a better reflection on inclined solid surface. Beam angle, energy concentration, while enhanced echo and to avoid the interference. Measure blind spots smaller
canisters measure will achieve good results. The low noise ratio, even in case of fluctuations can get
better performance. High frequency is the best choice for measuring solids and low dielectric constant.
How does radar level measurement work?
The device operates according to the FMCW method (FMCW = Frequency Modulated Continuous Wave). Electromagnetic pulses in the GHz range are sent to the medium at different frequencies between 77 and 81 GHz. Since the transmitter is constantly changing the frequency of the transmitted signal, there is a frequency difference between the transmitted and reflected signals. Subtract the frequency of the reflected signal from the frequency of the transmitted signal at that time to obtain a low-frequency signal proportional to the horizontal distance. This signal is further processed to enable fast, reliable and highly accurate level measurement
