Bürkert Type 8139 80 GHz radar level instrument

The Bürkert Type 8139 is a non-contact radar level measuring device for continuous level measurement. It is available with choices of an integrated antenna, a plastic horn antenna, a flange connection (DIN 2501) with encapsulated antenna system, or a clamp connection (DIN 32676, ISO 2852) with encapsulated antenna system for hygienic requirements.

The integrated antenna (G- or NPT connection) is suitable for level measurement of aggressive liquids, with special advantages for small vessels, while the plastic horn antenna (with mounting bracket) is suitable for measurements in open flumes or gauge measurement in water.

The high focus of the radar signal and the high measurement dynamics are said to allow correct measurement results even in small, narrow and high containers, as the risk of signal interference by installations, constructions and vessel walls is lower. Signal damping (for example due to signal running length, foam build-up or low dielectric values of the liquids) has a smaller effect.

The device offers continuous level measurement up to 30 m with a 4–20 mA, 2-wire connection and is adjustable using the display/configuration module and keys, or alternatively via PC-Tool with DTM.
