Pulsar® R80 Advanced 80 GHz non-contact radar

Magnetrol International

Pulsar® R80 is the latest radar non-contact level transmitter. It uses frequency modulated continuous wave (FMCW) of 80 GHz. The high-frequency waveform provides greater accuracy and resolution, and allows to be antennas and process connections as small as 3/4 NPT.

Pulsar® R80 is the latest model in the Magnetrol non-contact radar family. It uses a continuous 80 GHz frequency modulated (FMCW) microwave signal. The device has been designed on the recognized electronics platform previously used in the Eclipse® 706 GWR transmitters, Pulsar® R96 and Pulsar® R86 non-contact radars.

The use of the 80 GHz frequency for measuring the level results in a narrower beam of emitted waves - even 4°. The higher frequency also makes possible to use smaller antennas helping in installation of the device. An additional advantage is the circular polarization of the radar beam, which eliminates the need of difficult positioning antenna on the object in order to obtain the best signal reflection. As a conclusion - these features improve application versatility and allow for mounting in locations previously inaccessible to non-contact radars.

Pulsar® R80 firmware facilitates operation - configuration and solving problems that may arise in the process. The unique advantages of level transmitters include:
- active diagnostics - the radar itself diagnoses problem and suggests possible causes and the way for solving the problem,
- data logging and preview of the last 20 events, including shape of the echo,
- configuration and diagnostic parameters, configuration wizard - the user is guided step by step through device configuration,
- advanced, but at the same time easy to use, function of automatic extracting false echoes, with possibility of manual correction of the extraction curve,
- signal graph available in real time on the level transmitter display,
- the help stored in the device's memory eliminates the need to refer to the paper manual in most cases,
- friendly DTM HART® with graphical interface.
Principle of operation

FMCW modulated wave radars use the energy of microwaves directed at the surface of the measured medium. The amount of reflected wave depends on the dielectric constant of the material. FMCW radars send the wave continuously and the frequency is constantly changing. For 80 GHz radar, the frequency of the transmitter can start at 79 GHz and go up to 81 GHz. The transmitter compares the frequency it receives from the surface of the product with the frequency it is sending out at the moment. The detected frequency difference between the transmitted signal and the returning echo is a function of distance. The level is calculated based on the height of the tank and other configuration information.
