26530 Dual Probe Transducer System
PN 330500 MADE IN U.S.A.
VELOMITOR
100 mV/i ps
(4 mV/mm/s) R BENT LY
NEVADA
Description
The Dual Probe Transducer System consists of a proximity probe and a seismic or
Velomitor®
transducer installed at approximately the same point in a common
transducer
housing. This
transducer system is capable of making four separate measurements:
Shaft relative radial position (displacement) relative to the probe mounting
location, measured by the proximity probe;
Shaft relative radial dynamic motion (vibration) relative to the probe
mounting location, measured by the proximity probe;
Machine casing absolute vibration measured by the seismic vibration; and
Shaft absolute motion represented by the summation of the seismic
signal (after integration to displacement) and the shaft relative
displacement.
The Dual Probe Transducer System provides the its best measurement data
when
transducer housing is mounted on a portion of the bearing housing or
cover that is mechanically referenced to the bearing.
For complete machinery monitoring diagnostics using orbit analysis and shaft
centerline position information, two Dual Probe assemblies in an X-Y
configuration are required per radial bearing.
A probe support/oil sleeve is available as an option. It protects the
transducer
system from oil and provides additional support for the probe sleeve.
