Measurement technology specialist VEGA has introduced to the market a range of radar level transmitters which operate at a frequency of 80 gigahertz, allowing smaller antennas and resulting in a much smaller beam angle and better focusing. 


The focusing properties of a radar level transmitter depend on its operating frequency. Until now 26 GHz was regarded as the standard frequency, but by increasing to 80 GHz the antennas are up to three times smaller, resulting in a considerable gain in returned signal. 


For liquid and paste applications the VEGAPULS 64 offers a range of smaller process connections which are ideally suited to measure the contents of smaller vessels commonly found in the industry. With a much smaller beam angle, internal structures and mixing blades are not seen within the beam and allow the transmitter to track the level more accurately. 


For solids, applications of powders and rocks, the VEGAPULS 69 allows level measurement to be achieved even under the most difficult conditions. The options of aiming gimbal and air-purge connections allow complete installation and application flexibility. 


“Customer feedback has indicated?the benefits of the 80 GHz radar, with increased production, lower downtime, and ease of operation,” VEGA Australia Managing Director John Leadbetter said. 


The 80 GHz range is available with all approvals required for the industry. 


Another added advantage to the full range of transmitters is the ability to program and fault find via Bluetooth. This communication can be from a smart phone, tablet or laptop and can operate up to 25m from the transmitter. 


“This is now moving towards IIoT4.0,” Mr Leadbetter said. 


“With more than 100,000 units installed in various applications worldwide, this technology has proven market acceptability.”
