The VL Series is made specifically for solids
level measurement in containers. This sensor is designed for
bulk density as low as 0.2g/cm 3(12.5 lb./cu. ft.). The operating
principle is a vibration rod mounted with two piezo electric
elements; one providing vibration, and the other detecting changes
in the vibration frequency. The piezo crystal sets up a
330 Hz oscillation and is dampened by the detection of the bulk
material.
The VL series is compact for high and low level detection on
small and large silos us model VL21. With less than eleven inches
of insertion length the VL11 can be top or side mounted. The
top mount can be extended to provide high level alarms in silos
(use model VL21). The field selectable sensitivity allows this
product to be used on a range of dry media ranging from fluidized
powders to sticky medias. The single tine probe provides
a reliable level switch in products which may be sticky. The
single tine probe will not become clogged.
