MG8900 Series Non-Contact Radar Level Transmitter

MG8900 series non-contact radar transmitter adopts advanced signal processing technology, which is derived from unique echo processing technology to provide intelligent echo processing process. The measurement results with high repeatability, rapidity and reliability are obtained.
A feature of this series of radars is automatic suppression of false echoes. Echo processing technology can automatically detect and suppress false echoes from obstacles in containers. This function can be realized through local interface or through HART and unique software communication with at least two parameters.
Through radar measurement technology, measurement of non-contact and maintenance free is realized. As the transmission of microwave signal does not require medium, it is not affected by steam, pressure, dust or temperature in the process.

  • MG8900 Series

Product Features

● The graphical local interface (LUI) makes the operation easy to understand, and the quick start wizard is used to realize the plug and play settings. LUI display echo image is used for diagnosis;

● Communication by HART or PROFIBUS-PA;

● The minimum blind area is only 50mm to the end of the horn;

● It applies to large range (100m) and harsh working conditions;

● Simple collimator improves signal quality from inclined solid surface;

● 120GHz high frequency allows small speakers to be installed on small mounting tubes;

● On site intelligent signal processing improves measurement stability, and automatic false echo suppression function eliminates fixed interference.
