The K080ld NVI level switch is a mechanical system that is made to resound by an electronic exchanging operation. The medium to be measured should have a thickness of not less than 0.05 kç/dms. The single bar design avoids deposit format on. While the joined vibrating switch might be utilized within fine media and granular materials. At the point when the test is secured by a medium, the vibrations are damped. This change the reverberation recurrence is converted to an exchanging sign by electronic means.
