The VEGA VEGAPULS 21 is a compact radar level sensor designed for reliable non‑contact continuous level measurement of liquids and bulk solids in standard industrial applications. It operates with high‑frequency 80 GHz radar technology to deliver precise measurements independent of medium properties and changing process conditions. ([turn0search0][turn0search2])
Because the sensor features a plastic housing with protection rating IP66/IP67, Type 4X, it is suitable for use in water treatment, tank storage and small silos. The device supports a 4–20 mA/HART output for seamless integration into process control systems. ([turn0search0][turn0search2])
Not Recommended For:
• Applications requiring only local simple float switches
• Gas‑only or vapour‑only level measurement
• Confirm the measurement range requirement; UP56 supports distances up to 20 m.
• Verify whether your application requires bulk solids or liquid level measurement.
• Choose the appropriate process connection size and thread (G1½, 1½ NPT, R1½).
• Determine the desired output interface, such as 4–20 mA/HART.
• In addition, ensure the housing protection rating (IP66/IP67, Type 4X) meets your environment needs.
• Non‑Contact Ultrasonic 80 GHz Radar
The sensor uses high‑frequency radar pulses that measure level without contacting the medium. As a result, maintenance needs are reduced. [turn0search2])
• High Accuracy and Reliability
With typical accuracy around ±2 mm, the VEGAPULS 21 delivers exact measurement results that remain stable regardless of medium properties or conditions.
• Wide Application Flexibility
It is suitable for liquids and small bulk solids in water treatment, storage tanks, process vessels and plastic containers. Therefore, a broad range of simple industrial level tasks can be covered with one device.
• Robust Industrial Design
The plastic housing and total protection rating of IP66/IP67, Type 4X help ensure durability in wet and dusty industrial environments.
• Easy Integration
Featuring a standard 4–20 mA/HART output, the sensor can interface easily with PLC, DCS or other process automation systems. Consequently, system integration and setup are simplified.
