High frequency microwave impulses are coupled to a cable or rod and guided along the probe. The impulses are reflected by the product surface and received by the processing electronics.
Due to this measuring principle, the comprehensive adjustment with the product is no longer necessary. The instruments are adjusted to the ordered industrial electrode length. The shortable cable and rod versions are suitable for individual adaptation to the local conditions.
Even process conditions such as high dust and noise generation or strong steamy atmospheres do not influence the accuracy of the measurement.
Density fluctuations, different granulation or even fluidising do not influence the accuracy. This applies also to the change from dry to wet gravel.
Strong build-up on the electrode or on the vessel wall does not affect the measuring result.
With measuring ranges up to 30 m, the sensors are also suitable for high vessels. Temperatures up to 150°C and pressures from vacuum up to 40 bar cover a wide application range.
By using a coaxial guide tube, VEGAFLEX 65 operates completely unaffected by vessel installations such as e.g. heating spirals or struts. A special adjustment is not necessary.
