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 galvanized or stainless steel extension
tube.
- VR
51 - Extends up to 19.5', using a flexible cable
extension.
