Installation Instructions
Dual Probe Holder
Cat. No. EK-29000-DPH01
This document provides information to install the Allen-Bradley Dual Probe Holder. The Dual Probe Holder is designed to combine a displacement transducer and an Allen-Bradley 9000 series sensor (velocity or accelerometer) into a single housing. The Dual Probe Holder
can be used in conjunction with the Allen-Bradley XM provide shaft relative, case absolute, and shaft absolute measurements.
Note that the Dual Probe Holder is also functional with either one of the two sensors installed.
For more information on the XM-121 Absolute Shaft module, refer to the XM-121 Absolute Shaft User Guide (publication GMSI10-UM014x-EN-E). Refer to the specific sensor manual
for recommended wiring requirements and specifications for that sensor.

Important User Information
Solid state equipment has operational characteristics differing from those of electromechanical equipment. Safety Guidelines for the Application, Installation and Maintenance of Solid State Controls (Publication SGI-1.1 available from your local Rockwell Automation sales office or online at http:///literature.rockwellautomation.com) describes some important differences between solid state equipment and hard-wired electromechanical devices. Because of this difference, and also because of the wide variety of uses for solid state equipment, all persons responsible for applying this equipment must satisfy themselves that each intended application of this equipment is acceptable.
In no event will Rockwell Automation, Inc. be responsible or liable for indirect or consequential damages resulting from the use or application of this equipment.

About the Dual Probe Holder

The Dual Probe Holder provides a single housing for a non-contact eddy current probe and an Allen-Bradley 9000 series sensor. The Dual Probe Holder allows the eddy current probe and the 9000 sensor to be installed at the same point on the same bearing half. The Dual Probe Holder mounts on the machine casing and the installed sensors connect to a monitoring system such as the XM-121 Absolute Shaft module.
Figure 1 Dual Probe Holder Internal Side View
The Dual Probe Holder consists of a base that threads into the machine case, three conduit ports for wiring connections, a stinger of optional length, o-rings, an eddy current probe, a case vibration sensor, a jam nut, adjusting cage and knurling adjusting knob to secure the stinger to the base to maintain the probe-to-shaft gap. And the Dual Probe Holder cover screws onto the base of the holder. See
The location in which the probe and holder is installed determines which stinger you use. Refer to Dual Probe Holder Ordering Information on page 5.
