Vibrating Rod: VR Series

The VR Series of vibrating rods are piezoelectric devices with a single blade-shaped vibrating element. Material coming into contact with the probe dampens the vibration; material falling away returns the unit to normal vibration. This allows the unit to be used for high or low level indication.

The VR Series includes three different models:

  1. VR 21 - Standard unit with an insertion length of 7.37"
  2. VR 41 - Extends up to 13', using a solid extension tube
  3. VR 51 - Extends up to 19.5', using a flexible cable extension
Features
  • Suitable for high and low level indication
  • Detects extremely light, fluffy materials and materials with low dielectric constants
  • Unique "blade" probe design reduces false alarms caused by buildup
  • Insertion length adjustable from 7.37" to 19.5'
  • Switch selectable high/low fail-safe
