02 · Application & Fault Scenarios
Application
Machinery absolute vibration monitoring
The PR 9268 family measures absolute vibration on machinery casings and supplies a vibration-velocity signal to the associated monitoring or protection equipment.
Bearing-housing vibration
Rotating machinery
Machinery protection
Vibration monitoring
Fault / Search Scenario
When this part is commonly investigated
No vibration output
Abnormal signal level
Cable break or short
Sensor replacement
A failed transducer can interrupt the vibration-monitoring chain and may affect machinery protection or contribute to an operational shutdown.
03 · Installation, Connection & Diagnostics
Mounting
Surface Use a flat, clean and rigid mounting surface.
Mounting holes Three M6 through bores or three M4 blind-hole threads; blind-hole thread depth up to 10 mm.
Cable Avoid torsion, elongation and mechanical damage during cable routing.
Open Cable End
Green Signal high
Blue Signal low
Red Transducer housing
Shield Cable shield; grounding arrangement follows the installation requirements.
Basic Diagnostics
Emerson specifies resistance, insulation-resistance and signal-generation checks for fault analysis. Approximately 1875 Ω indicates an intact transducer circuit; 0 Ω indicates a short circuit, while infinite resistance indicates an interruption.
Installation and diagnostic information: Emerson MHM-97479, Rev. 3.9.

06 · Frequently Asked Questions
Is PR9268/207-100 configured for vertical vibration measurement?
Yes. PR9268/207-100 is a PR 9268/20x configuration specified for vertical measurement.
What cable configuration does PR9268/207-100 have?
The model uses a 10 m non-armored cable with an open cable end. This configuration should be matched when replacing an installed sensor.
What resistance should be measured when checking a PR9268/207-100?
Emerson specifies approximately 1875 Ω for an intact PR 9268/20x transducer circuit. A 0 Ω reading indicates a short circuit, while infinite resistance indicates an interrupted circuit or cable break.
What should be checked when the sensor produces no vibration signal?
Check the transducer circuit, insulation resistance, cable connections and signal generation. The installation guide provides resistance and signal-generation procedures for fault analysis.
Can another PR 9268 variant be used instead of PR9268/207-100?
The complete configuration should be matched before substitution, including measurement direction, cable construction, cable length and cable termination. A similar-looking PR 9268 part number should not be treated as a direct replacement without checking these details.
Technical information is based on Emerson PR 9268 installation documentation. Compare the complete nameplate/order code and installed measurement arrangement before replacement.
