Vibrating Level Sensor VP11

Vibrating Level Sensor VP11

VLS-VP11

Description

Applications
Solid detection. Integration into small equipment
 

Features
  • Flat detector
    • The detector is a flat vibration plate and only a small portion is projected into the tank, ensuring little degradation over time.
  • Extremely robust
    • With piezoelectric crystal, no moving parts are required. The sensor is made very simple, offering long service life.
  • User adjustable sensitivity
    • Sensitivity is adjustable to suit specific applications.
  • Easy installation and low cost
    • Threaded (G 3/4) and sanitary flange type (1-1/2S) process connections are available.
  • Compact and lightweight
    • Vibration plate O.D. 22.5, approximately 220g (VP11N) or 300g (VP11F)

Principle of Operation
Principle of Operation

The sensor uses a piezoelectric crystal to cause pulsed vibration on the plate. The vibration is followed by ringing.
The ringing decreases as time passes. How it decreases depends on the force applied to the plate.
With material covering the plate, the ringing decreases more rapidly than without material. The sensor compares how the ringing decreases to determine material presence.
The pulsed vibration is synchronized with the ringing to achieve a wide sensitivity adjustable range.
