Take note of safety instructions for Ex applications Please note the Ex specific safety information that you can find at www.vega.com and that comes with each instrument. In hazardous areas you should take note of the appropriate regulations, conformity and type approval certificates of the sensors and power supply units. The sen- sors must only be operated on intrinsically safe circuits.
A special time stretching procedure allows reliable and precise measure- ment of the extremely short times. The VEGAPULS 67, SR 68, 68 radar sensors work with low emitted power in the K-band frequency range. Measuring principle VEGAPULS 69 The instrument emits a continuous radar signal via its lens-shaped antenna.

Mounting Cement silo Fig. 19: Level measurement in a cement silo with VEGAPULS 69 Cement is stored in high and very slender silos. The abrasive properties as well as the extreme dust generation during filling make high demand on the level measurement. The VEGAPULS 69 sensor is the optimum solution for level measure- ment.
