Burkert – Type 8189 – Level Measurement Device with Guided Radar Sanitary Version

 Level Measurement Device with Guided Radar Sanitary Version

The Type 8189 is a level measurement device with interchangeable rod probe, designed for continuous level measurement. The unit is suitable for liquids, for industrial use in all areas of process technology. But the main application targets are in Food and Beverage (F&B) and pharmaceutical tanks to the new rod in stainless steel 1.4435 with Ra < 0.76 µm. For applications with corrosive liquids a PFA coated version is available. Even process conditions such as strong steam generation, density fluctuations or changes of the dielectric constant do not influence the accuracy of the measurement. Build-up or condensation on the probe or vessel wall does not influence the measurement result.
