Which installed hardware must be paired with PR9268-301-100?

Use PR9268-301-100 with the documented PR9268 horizontal case-seismic measurement components: AMS 6500 A6120 or compatible monitor, Horizontal machine-case mounting point, Field terminal and shield arrangement.

How should the Measuring orientation value for PR9268-301-100 be verified?

Confirm the complete nameplate and order code before work; the documented measuring orientation is Horizontal; up to 100 degC.

What connection detail is critical when installing PR9268-301-100?

Preserve every conductor, connector and shield identity, then follow the model-specific connection arrangement described in the controlling Emerson document.

What configuration record should be retained when replacing PR9268-301-100?

Retain the as-found position, cable construction, cable or channel identity, gap or scaling value, diagnostics and final functional-test result.

Can PR9268-301-100 replace a similar Emerson model without engineering review?

No direct substitution should be assumed; verify the full order code, measuring function, interface, cable or channel arrangement and the approved PR9268 horizontal case-seismic measurement configuration.

Information

Overview Manuals Common Applications Product Precautions

Emerson PR9268-301-100 is pr9268 electrodynamic velocity sensor. It converts horizontal machine-case velocity into a self-generated electrical signal for continuous monitoring and protection.

Designed for horizontal measuring axes
Includes a five-metre armored open-ended lead
Operates without an external transducer supply
Supports absolute vibration velocity measurement

PR9268-301-100 operates with AMS 6500 A6120 or compatible monitor, Horizontal machine-case mounting point, Field terminal and shield arrangement, Velocity alarm and trend configuration.

Engineered applications include Horizontal turbine casing vibration, Compressor bearing-housing monitoring, Motor and gearbox case motion, Balance-of-plant protection.

Important Notice: Align the sensing axis horizontally, maintain full base contact, support the five-metre cable and verify polarity plus channel scaling before automatic protection is restored.

Horizontal turbine casing vibration

Measures lateral case motion at turbine bearings.

Compressor bearing-housing monitoring

Feeds horizontal housing velocity to the protection rack.

Motor and gearbox case motion

Supports rotating-equipment condition trending.

Balance-of-plant protection

Provides a direct case-seismic input for alarms and shutdown logic.

Read the applicable Emerson machinery-monitoring instructions before work. Verify PR9268-301-100 and the installed PR9268 horizontal case-seismic measurement configuration.

Confirm the full PR9268-301-100 marking, horizontal measuring orientation and assigned machine location before removal.

Place the monitored machine and protection logic in the approved maintenance state before sensor work.

Use the three M6 through bores or M4 blind-hole threads without exceeding the documented 10 mm blind-thread depth.

Support the 5 m armored cable and maintain at least the documented 35 mm bending radius.

Preserve the measuring axis and housing contact surface; do not introduce tilt, rocking or loose mounting.

Identify both open-ended cable conductors and preserve shield and polarity continuity to the monitor channel.

Measure the sensor circuit and insulation condition before reconnecting it to the monitoring input.

Run the machine under controlled conditions and verify velocity response, phase behavior and alarm logic.
