The Aplus Finetek Sensor vibrating probe level switch provides level measurement for most materials in powder or bulk through the use of 2 piezoelectric elements built in on the vibration tube. The first element is triggered by a pulse signal to transport vibration energy out; the other receives the vibration and transmits it to the output electric signal. The probe level switch requires no calibration and is designed to prevent material accumulation on the probe.Aplus Finetek Sensor Inc.; 909-598-2488; www.aplusfine.com
