The Aplus Finetek Sensor vibrating probe level switch provides level measurement for most bulk powder materials, including milk powder, ground coffee, sugar andProbe level switch grains. The vibrating probe is operated using two piezoelectric elements built-in onto separate vibration tubes. The design of the switch prevents accumulation of material on the probe. No calibration is needed.
