|  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:
- VR 21 - Standard unit with an insertion length of 7.37"
- VR 41 - Extends up to 13', using a solid extension tube
- 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
