VEGAFLEX 82 TDR sensor for continuous level measurement of bulk solids
$1,200.00
The VEGA VEGAFLEX 82 is a robust TDR guided wave radar sensor designed for continuous level measurement of bulk solids in industrial silos and storage vessels. Its guided microwave radar technology delivers precise and reliable level readings even under challenging conditions such as dust, condensation or buildup.
Because the sensor supports multiple probe options (cable, rod or combination), it adapts well to a wide range of bulk materials, from light powders to heavy solids. In addition, the instrument provides flexible output interfaces for easy integration into process systems.
Not Recommended For:
• Non‑solid applications such as free‑flowing liquids without waveguides
• Very low dielectric materials that fall below the detectable threshold without probe end tracking

Selection Notes
• Confirm the bulk solid type and dielectric constant to ensure reliable TDR measurement. The sensor adapts to most solids due to automatic probe end tracking.
• Verify the measurement range needed; VEGAFLEX 82 supports long distances up to 75 m with cable probes.
• Choose between cable or rod probes, depending on silo height and installation geometry.
• Determine the appropriate process fittings such as threaded (≥ G¾/¾ NPT) or flanged (≥ DN25/1″) connections.
• In addition, define the output and communication protocol required — including 4–20 mA/HART, Foundation Fieldbus, Profibus PA or Modbus.
Why Choose the VEGA VEGAFLEX 82
• Continuous Guided Wave Radar for Solids
The VEGAFLEX 82 uses high‑frequency microwave pulses guided along a cable or rod to determine level. Therefore, it achieves accurate readings even with dust, steam or buildup.
• Automatic Probe End Tracking
When the dielectric constant of the material is low or echoes are weak, the probe end tracking feature maintains measurement stability. As a result, virtually all bulk solids can be measured reliably.
• Flexible Probe Options and Installation
Cable and rod probes can be shortened on site, offering flexible planning and simplifying installation in various silo sizes. Consequently, different bulk solids applications are supported with one sensor family.
• Broad Output and Integration Options
Besides standard 4–20 mA/HART, there are digital communication choices such as Profibus PA, Foundation Fieldbus and Modbus, enabling seamless integration with automation systems.
• Industrial‑Grade Construction and Protection
The sensor housing and wetted parts are available in materials such as stainless steel and PA. In addition, protection ratings up to IP66/IP68 ensure durability in harsh industrial environments.
FAQ
Q: What principle does VEGAFLEX 82 use for level measurement?
A: It uses TDR guided wave radar, where microwave pulses travel along a probe and reflect from the product surface to determine level.
Q: Can the sensor measure different bulk solids?
A: Yes. Automatic probe end tracking enables reliable measurement of light and heavy solids, including powders, plastics and cement.
Q: What outputs are available on VEGAFLEX 82?
A: Outputs include 4–20 mA/HART, Modbus, Profibus PA and Foundation Fieldbus.
Q: What installation connections are supported?
A: The instrument supports threaded (≥ G¾/¾ NPT) and flanged (≥ DN25/1″) process connections.
