In industries handling powders, grains, or granular materials, accurate level measurement can be particularly challenging. Dust, irregular surfaces, and changing material properties often cause false readings in traditional measuring instruments. To overcome these challenges, the VEGAPULS 67 Radar Level Transmitter provides a non-contact, maintenance-free solution designed specifically for continuous level measurement of bulk solids.

Engineered by Vega, the VEGAPULS 67 stands out for its robust radar technology, high signal sensitivity, and reliable performance even under extreme process conditions. It’s a preferred choice in industries such as cement, mining, food, agriculture, and plastics where precision and reliability are essential.

What Is the VEGAPULS 67?

The VEGAPULS 67 is a non-contact radar level transmitter optimized for the measurement of bulk solids, powders, and granulates.

It uses radar waves to determine the distance between the sensor and the material surface — providing continuous and accurate level data regardless of dust, noise, or process pressure.

Because the measurement is contactless, the instrument is wear-free and maintenance-free, making it ideal for applications involving abrasive or dusty media.

How the VEGAPULS 67 Works

The VEGAPULS 67 operates on the radar time-of-flight principle:

1. The transmitter emits high-frequency radar pulses toward the surface of the bulk material.

2. These pulses reflect back from the material surface to the antenna.

3. The transmitter measures the time taken for the signal to return.

4. Based on the speed of light, the time delay is converted into a distance measurement.

5. The internal electronics then calculate the material level and transmit it as a 4–20 mA or digital output signal.

Because radar waves are unaffected by temperature, pressure, or dust, the VEGAPULS 67 ensures stable and accurate readings even during material filling or discharge cycles.
