VEGAPULS63 - Radar sensor for continuous level measurement of liquids - 

PS63.DXNFDHDMAX

(For aggressive liquids or under hygienic requirements)

The VEGAPULS 63 uses a non-contact radar (TDR - Time Domain Reflectometry) principle to measure the level of aggressive liquids or in hygienic applications. The sensor emits microwave pulses, which are reflected by the liquid's surface, and the time it takes for these pulses to be received back by the antenna system is used to calculate the distance to the surface, and therefore the liquid level. This method is unaffected by process conditions like pressure, temperature, or product properties.

How it Works

1. Microwave Emission: The sensor's antenna system sends extremely short microwave pulses in the direction of the product surface.
2. Reflection: The surface of the measured product reflects these pulses back towards the sensor.
3. Signal Reception: The antenna system receives the reflected signals.  
4. Time Measurement: A special time-stretching procedure allows for precise measurement of the very short time taken for the signal to travel from the sensor to the product surface and back.
5.  Level Calculation: The sensor uses the time-of-flight to determine the distance to the product surface and then calculates the actual level in the vessel.

Key Characteristics

• Application: Ideal for measuring aggressive liquids or in applications with high hygienic demands, such as storage tanks, process vessels, and reactors.
• Encapsulated Antenna: The antenna system is sealed and protected from contamination, ensuring maintenance-free and long-term operation.
• Front-Flush Mounting: The sensor's front-flush mounting allows for optimal cleanability, which is important in hygienic applications.
• Non-Contact Measurement: The process is entirely non-contact, meaning the readings are not influenced by factors like product properties, pressure, or temperature.

Application area 

The front-flush mounting of the encapsulated antenna system ensures optimum cleaning even with strict hygienic requirements.

VEGAPULS 64 Radar sensor for continuous level measurement of liquids

PS64AXHRAIHXKMXXX

(All-round radar instrument with 80 GHz – the frequency of the future)

The VEGAPULS 64 is a radar level sensor that measures the distance to a product surface by emitting a continuous microwave signal, receiving the reflected echo, and calculating the frequency shift between the emitted and received signals, which is proportional to the distance and thus the level. Its key principle is frequency shifting, which, combined with a narrow, highly focused 80 GHz radar beam, allows for accurate and reliable non-contact level measurement, even in challenging conditions with poor reflectivity, surface turbulence, or internal tank obstructions.

How it Works

1. Signal Transmission: The VEGAPULS 64 sends out a continuous radar signal (microwaves) from its antenna.
2. Signal Reflection: The surface of the liquid reflects this signal back towards the sensor.
3. Signal Reception: The antenna receives the reflected signal (echo).
4. Frequency Shifting: A difference in frequency between the emitted and received signal (frequency shift) occurs due to the Doppler effect and the distance to the product surface.
5. Distance Calculation: This frequency shift is directly proportional to the time it takes for the signal to travel to the product and back. The sensor uses this to calculate the distance to the product surface.
6. Level Calculation: The determined distance is then used to calculate the level within the vessel and is outputted as a measured value.

Key Advantages

• 80 GHz Technology: The high frequency results in a very narrow and focused beam angle.
• Improved Accuracy & Reliability: The concentrated beam allows the sensor to avoid interference from tank fittings or agitators and get better reflections from poorly reflective media like compressed gases/liquids, leading to more accurate and reliable measurements.
• Non-Contact Measurement: The sensor operates without touching the product, reducing wear and tear and leading to maintenance-free, high plant availability.
• Minimal Interference: The narrow beam angle helps to avoid unwanted reflections from tank bottoms, even at low levels.

Application area

Special advantages are the small process fittings for small tanks or tight spaces. The very good signal focusing allows use in vessels with many internal installations.

Vegapuls 69 Radar sensor for continuous level measurement of bulk solids -PS69.AXCFAAHXAMXXXEN

(All-round radar instrument with 80 GHz – the frequency of the future)

The VEGAPULS 69 is a radar sensor that uses high-frequency (80 GHz) microwave signals to measure the continuous level of bulk solids in containers and silos. The sensor emits a highly focused radar beam that strikes the material surface and is reflected back to the sensor. By measuring the time it takes for the signal to return and the intensity of the reflection, the system calculates the distance to the product surface and, consequently, the material's level. Its high frequency and narrow beam angle allow for reliable measurements even with internal obstructions and poorly reflecting materials like powders, ash, and sawdus

How it Works (Step-by-Step)

1. Signal Transmission:
   The VEGAPULS 69 transmits a radar signal at a frequency of approximately 80 GHz into the container or silo.
2. Focused Beam: The 80 GHz frequency allows for a very narrow, focused radar beam (around 4°), which minimizes interference from internal installations or buildup on the vessel walls.
3. Reflection: When the radar beam hits the surface of the bulk material, the signal is reflected back toward the sensor.
4. Signal Reception: The sensor receives these reflected signals.
5. Time of Flight: The internal electronics measure the time it takes for the radar pulse to travel from the sensor to the product and back.
6. Level Calculation: Using this time-of-flight data and the known speed of the radar waves, the sensor calculates the exact distance to the product surface.
7. Level Output: This distance is then converted into a level measurement and can be outputted to a control system.

• High Frequency (80 GHz): This enables excellent signal focusing, reducing background noise and improving reliability.
• Narrow Beam Angle (4°): The focused beam prevents reflections from vessel walls and internal structures from interfering with the measurement of the bulk material.
• High Dynamic Range (120 dB): This allows the sensor to detect even very weak reflections from materials with poor reflective properties, such as plastic powders, fly ash, and dry sawdust.
• Non-Contact Measurement: The sensor operates without physical contact with the product, preventing wear and contamination. 

Application area

Special advantages are the small process fittings for small vessels or tight spaces. The very good signal focusing allows use in large silos or vessels with many internal installations.
The VEGAPULS 69 is a sensor for continuous measurement of bulk solids under different process conditions. It is ideal for level measurement in very high silos, large bunkers and segmented vessels. Thanks to the very good signal focussing a simple setup and reliable measurement is ensured. The VEGAPULS 69 can be equipped with an encapsulated plastic antenna or a lens antenna integrated in the metal flange. This enables the optimum adaption to different application areas.
