The latest generation of radars doesn’t consider condensate on the sensor as an issue. In fact, the VEGAPULS 64 is completely unaffected by condensation or buildup on the antenna, and thus accurately detects the liquid level. Equipped with best-in class, smallest antenna of its kind and exceptional focusing, the VEGAPULS 64 delivers outstanding performance – every single time. Simply world-class!

Messy Conditions – So What?
The VEGAPULS 64’ antenna system is encapsulated in PTFE or PEEK, thus ensuring the absence of cavities or crevices in which the product can accumulate. The material’s surface is very finely processed with diamond tools, thereby also considerably reducing product adhesion.

Optimized signal processing makes VEGAPULS 64 independent of buildup.Image Credit: VEGA
What’s more, interference caused by buildup on the antenna system are filtered out by unique software algorithms. Moreover, signal attenuation caused by product deposits is largely compensated, owing to the high dynamic range of the sensor. Thus, the level is reliably detected even in cases of sensor contamination.
Key Benefits
- High measurement certainty, even in situations where product deposits collect during operation
- Level measurement that is independent of condensation and the quick availability of the system after cleaning cycles
- Non-contact level measurement, thus enabling maintenance-free operation
A Radar Beam Focused Like a Laser!
Good focusing delivers security
The newest cutting-edge technology from a world leader: the unrivaled focusing of VEGAPULS 64. This enables the radar beam to be targeted at the liquid surface with pinpoint accuracy, thus avoiding internal obstructions like heating coils and agitators.
This new generation of level sensors is also entirely unaffected by condensation or buildup and has the smallest antenna of its kind.

Level in the Focus
VEGAPULS 64 has an operating transmission frequency of 80 GHz. With an antenna of 80 mm, this results in a beam angle of only 3°. The radar level sensor receives only definitive, distinct reflections from the product surface. This makes the level measurement more reliable and accurate.

Excellent signal focusing allows use even in confined spaces. Image Credit: VEGA
By comparison: a conventional radar level sensor with 26 GHz transmission frequency and an antenna of the same size has a beam angle of around 10°. As a result of the considerably wider signal beam, agitators, fittings or buildup on the vessel wall cause interference that can affect the measuring result.

Key Benefits
- Considerably more straightforward setup and commissioning, even with complex vessel internals
- High accuracy, even when the level sensor is mounted close to the tank wall
- Increased measurement certainty over the entire measuring range through better focusing
The Ultimate for Small Tanks
Small process fittings extend the area of application for radar
Regarding contactless level measurement of liquids in small containers, smaller is better. With the smallest antenna of its kind, VEGAPULS 64 is simply the best! With excellent focusing and insensitivity to condensation or buildup, this new radar sensor is really exceptional.

Small but Mighty
VEGAPULS 64 operates with a transmission frequency of 80 GHz. This corresponds to a factor of 3 compared to the technologies used until now. As a result, the antenna system and the process fitting can have correspondingly smaller dimensions.

That makes radar level measurement technology more interesting for a wider range of applications. Existing vessels with small process fittings can be equipped with radar sensors without first carrying out expensive modifications.

- Simple retrofitting of existing facilities, without modification
Applications
Thickener for Sugar Beet Juice
Level measurement in a thickener
Thickening of the thin juice extracted from sugar beet by the reduction of excess water in multiple stages at the evaporator station. This evaporation process involves the use of vacuum and heat. The evaporation process involves the liquid in the evaporator to boil so violently that great amounts of vapor are formed. Thus, a level sensor is required in the monitoring and control of the thickening process.

Ice Cream “Premix” Mixer
Level and pressure measurement during the mixing of ice cream ingredients
The ice cream ingredients are accurately weighed and fed accordingly into a mixing tank, where the "premix" is made. After this, the premix passes through the homogenizer at a pressure of around 140 bar, following which it is pasteurized at 80 °C. To achieve this, the level in the premix vessel and the pressure in the pipeline leading to the homogenizer need to be constantly monitored, to ensure the continuous production of ice cream.
