The VEGA VEGAPULS 31 is a compact radar sensor designed for continuous non‑contact level measurement of liquids and small bulk solids in standard industrial applications. It operates with high‑frequency 80 GHz radar technology, delivering precise and reliable readings regardless of medium properties or environmental changes.

This sensor features a built‑in on‑site display and simple three‑button operation, helping operators check levels directly on site. It also supports 4…20 mA with HART output for easy integration into control systems.

Typical applications include water treatment, storage tanks, plastic IBC containers and small silo systems.

Not Recommended For:
• Very simple point‑level detection tasks where a basic float is sufficient
• Gas‑only measurement or environments with no liquid surface to detect

Selection Notes

• Confirm the measurement range requirement. VEGAPULS 31 typically supports up to 15–20 m level ranges.
• Verify whether your application is for liquid or small bulk solids.
• Choose the correct process connection such as G1½, 1½ NPT or R1½ thread.
• Determine the required output interface (4…20 mA/HART).
• In addition, ensure the housing protection rating (IP66/IP67, Type 4X) matches environmental conditions.

Why Choose the VEGA VEGAPULS 31

Non‑Contact Radar Measurement
The sensor uses 80 GHz radar to measure level without contacting the medium. Therefore, measurement stays unaffected by foam, vapour or changing fluid properties.

High Precision & Reliability
With typical accuracy of ±2 mm, VEGAPULS 31 supplies consistent, repeatable level data for process control.

On‑Site Display & Easy Operation
An integrated display and three‑button interface allow operators to view level values and set parameters directly at the sensor.

Flexible Output Options
Standard 4…20 mA with HART communication helps integrate the sensor into PLC or DCS systems.

Robust Industrial Design
The plastic housing with IP66/IP67, Type 4X protection ensures durability in wet and dusty industrial environments.

FAQ

Q: What measurement principle does the VEGAPULS 31 use?
A: It uses 80 GHz radar pulses that reflect off the medium surface and return echoes to determine level.

Q: Does it have a local display?
A: Yes. The sensor includes an on‑site display with simple button operation for easy adjustment.

Q: Can it measure both liquids and solids?
A: Yes. It is suitable for liquids and small bulk solids in standard industrial applications.

Q: What outputs are supported?
A: The VEGAPULS 31 supports 4…20 mA with HART for connection to automation systems.

Q: What protection rating does it have?
A: It features IP66/IP67, Type 4X protection for reliable performance in harsh environments.
