Abstract
1. VEGAPULS 64 – Technology
A. Worlds first 80 GHz radar level sensor for liquids
VEGA introduces VEGAPULS 64, the first 80 GHz frequency liquids radar level sensor on the market. This frequency allows considerably better focusing of the radar beam, making measurement much easier and more reliable, even under difficult conditions, such as tanks fitted with heating coils, baffles or agitators.
Until now, a radar sensor using 26 GHz frequency and an 80 mm diameter antenna had a beam angle of approximately 10°. With the same antenna size, a VEGAPULS 64 has only a 3° beam angle. This enables the sensor to be used in vessels with many internal installations or heavy build-up on the walls, as its focused microwave beam simply avoids them. Also due to its ultra-wide dynamic range, even foaming, turbulent product surfaces, condensation or antenna build-up have little or no effect. It also measures low dielectric products much more reliably with an accuracy of ±2 mm, over a range of up to 30 m.
The VEGAPULS 64 is ideal for use in the chemical, oil and gas, pharmaceutical and food industries, because of its resistant materials and hygienic designs. Thanks to its small antenna – the smallest version is no larger than a £1 coin – very compact process fittings are available, which means the sensor can offer an alternative for very small process vessels. In addition to applications in mainstream manufacturing and processing industries, the sensors open up application possibilities in pilot plants and even laboratories, which, for space reasons, could not use radar level technology until now.
New radar level sensor VEGAPULS 64 for liquids: The smallest antenna is no bigger than a £1 coin, an ideal solution for installation in small containers, busy internal structures and agitators, or for mounting close to the vessel wall in larger containers.
