High Frequency Radar Level Transmitter PCM112

Product Overview:

The radar level meter antenna emits extremely narrow microwave pulses (80GHz), which propagate at the speed of light in space. When it encounters the surface of the measured medium, some of its energy is reflected back and received by the same antenna. The time interval between transmitting and receiving pulses is proportional to the distance from the antenna to the surface of the measured medium. Due to the extremely high propagation speed of electromagnetic waves, it is difficult to confirm the time interval between the transmitting and receiving masons (in the nanosecond range). The high-frequency radar level meter uses a special demodulation technology to accurately identify the time interval between the transmitting and receiving masons, thereby further calculating the distance from the antenna to the surface of the measured object.

Principle: The radar level antenna emits narrow microwave pulses, which are transmitted downwards through the antenna. After the microwave comes into contact with the surface of the tested medium, it is reflected back and then received by the antenna system. The signal is transmitted to the electronic circuit and automatically converted into a level signal (because the microwave propagation speed is extremely fast, the electromagnetic wave reaches the target and is reflected back to the receiver, which takes almost an instant)The reference surface for measurement is the bottom surface of the thread or the sealing surface of the flange.

Features

■ Almost free from corrosion and foam; Almost unaffected by changes in water vapor, temperature, and pressure in the atmosphere.

■In remote target detection and strong smoke and dust environments, it can detect smaller targets than microwave radar and achieve more accurate positioning, with higher resolution and stronger confidentiality.

■The small beam angle and concentrated energy enhance the echo capability while also helping to avoid interference.

■The measurement blind spot is smaller, and good results can also be achieved for small tank measurements.

■Using millimeter wave bands with higher frequencies than Ku band radar, resulting in high accuracy.

■The extremely narrow beam and penetration ability make it more adaptable to ultra complex working conditions without compromising measurement performance.

Applications

■Chemical industry

■Water level detection

■Coal silos, ash silos, oil tanks, cement powder tanks, etc

■Water storage tanks, acid-base storage tanks, slurry storage tanks, solid particles
