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:
- 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
