Emerson PR9268/201-000 Vertical Electrodynamic Velocity Sensor
A self-generating velocity sensor for absolute machine-casing vibration, configured for vertical measurement with a 5 m armored cable.
Product Identification
Emerson PR9268/201-000 is a PR9268 electrodynamic sensor for absolute vibration velocity. The 20 measurement code selects vertical installation, the cable code 1 selects a 5 m armored cable and the cable-end code 0 selects a Harting plug.
The moving-coil sensor generates an output proportional to casing vibration velocity and does not require an external excitation supply. Its published 4–1000 Hz response suits machinery-protection measurements on turbines, compressors, pumps, fans and related rotating equipment.
Mounting direction, cable route, monitor input and mechanical condition must be retained as one measurement chain.

Functions
Absolute casing measurement
Converts mechanical vibration of the sensor body into a voltage proportional to vibration velocity.
Vertical-axis execution
The 20 code establishes the orientation used for the published transverse-response data.
Protected integral lead
The 5 m armored cable protects the fixed sensor connection along the installed route.
Machinery-protection input
Feeds a compatible vibration monitor for continuous casing-vibration supervision.
Applications
Bearing-housing vibration
Vertical absolute-vibration measurement on rotating-machine bearing structures.
Turbomachinery protection
Velocity input for turbine, compressor, pump or fan monitoring systems.
Legacy sensor renewal
Like-for-like service where orientation, cable construction and connector must remain unchanged.
Lifecycle
Record PR9268/201-000, mounting orientation and stud, monitor channel, cable path and accepted vibration baseline.
Install on a prepared flat surface, preserve orientation and protect the armored lead from strain.
Check polarity, cable continuity where permitted, resting output, live vibration response and monitor alarms.

FAQ
What does the 20 code mean in PR9268/201-000?
It identifies the PR9268 execution intended for vertical vibration measurement.
Which cable is supplied with PR9268/201-000?
The ordering code selects a 5 m armored cable terminated with a Harting plug.
Does PR9268/201-000 need an external sensor supply?
No. Its electrodynamic moving-coil element is self-generating; the connected monitor receives the sensor output.
What should accompany a PR9268/201-000 quotation request?
Provide the full sensor label, mounting direction and stud, monitor-channel details, connector photographs, cable route and vibration baseline.
How is a replacement PR9268/201-000 validated?
Verify secure vertical mounting, correct polarity, undamaged cable and connector, plausible live response and the approved alarm tests.
