Generates a signal from absolute mechanical vibration through an electrodynamic spring-mass system.
Product Identification
PR9268/201-100 is an Emerson EPRO electrodynamic velocity-sensor execution in the PR9268 20x family for vertical measurement direction.
The spring-mass sensor is self-powered and measures absolute mechanical vibration without an external excitation supply.
The complete /201-100 suffix remains the ordering identity for the specific cable and mechanical execution and should not be shortened during replacement.

Applications
- Absolute bearing-housing vibration monitoring on rotating machinery.
- Vertical vibration measurement in compatible protection or condition-monitoring systems.
- Legacy replacement where mounting, sensitivity and cable execution are documented.
- Machine-health measurements requiring a self-powered velocity sensor.
Lifecycle
- Record the full sensor label, mounting direction, cable route, monitor channel and alarm settings.
- Inspect the mounting face, fastener, cable armor or sheath and connector condition.
- Install in the approved vertical orientation with secure mechanical coupling.
- Verify polarity, baseline, sensitivity, trend behavior and alarm-channel operation before service.
FAQ
Q01What should accompany a PR9268/201-100 enquiry?
Send the full sensor label, mounting and cable photographs, measurement direction, monitor channel, sensitivity record, quantity and destination.
Q02Can a horizontal PR9268 replace PR9268/201-100?
No. The spring-mass orientation is part of the sensor execution; use the measurement direction specified for the installed point.
Q03Does PR9268/201-100 require an external excitation supply?
The electrodynamic PR9268 sensor is self-powered, but the connected monitor channel and wiring still must match the approved system.
Q04What mounting issue most affects PR9268/201-100 data quality?
Loose, uneven or contaminated mounting can change the mechanical coupling and should be corrected before evaluating the signal.
Q05What proves PR9268/201-100 is ready after replacement?
Confirm exact execution, correct vertical orientation, secure mounting, stable baseline, correct polarity and passed channel and alarm tests.
