DEFrom bitumen to sulphur – hot and tough
Heavy demands on instrumentation
The distillation by-products bitumen and sulphur are stored at a temperature of approximately 200°C.
Due to high product temperature and heavy buildup, only a few measuring techniques are suitable for level measurement in this area.
VEGAPULS 62 – level measurement with radar
The non-contact measuring principle radar lends itself especially well to level measurement in high temperatures and adhering products. By means of a temperature adapter, the sensor is suitable for use in temperatures up to 200°C. To reduce condensate build-up on the antenna system, it is advisable to insulate the mounting boss. If buildup is especially heavy, the mounting boss can even be heated.
VEGABAR 65 – level measurement in high product temperatures
The pressure transmitter VEGABAR 65 is well adapted for hydrostatic level measurement of bitumen. Thanks to its metallic METEC measuring cell with self-compensating temperature reaction, the instrument has outstanding thermal characteristics. The special construction of the measuring cell assures temperature decoupling between process fitting and electronics, and thus enables implementation up to 200°C.
