PR9268 / 60x-000 FAMILY
High-Temperature Absolute Vibration Measurement
Emerson PR9268/601-000 is an electrodynamic velocity sensor for absolute vibration measurement on rotating machinery. This exact configuration belongs to the PR9268/60x-000 vertical high-temperature family and combines a stainless-steel sensor body with a 5 m armored cable and Harting connection.
Its spring-mass measuring principle produces an electrical signal proportional to vibration velocity. The 60x-000 design is intended for applications where the sensor must operate in higher-temperature machinery environments than the standard 20x/30x versions.

EXACT CONFIGURATION
/601-000
|
|
01 / MEASURING PRINCIPLE
Seismic Velocity Sensing
The PR9268 uses a low-tuned seismic measuring principle with electrodynamic mechanical-to-electrical conversion.
|
A measuring coil is suspended by membrane springs and acts as the seismic mass. Above the sensor's resonance frequency, the coil remains comparatively stationary while the housing follows the vibration of the monitored machine. The relative movement between the housing and coil generates a voltage proportional to vibration velocity.

03 / SENSITIVITY
Load-Dependent Output
The 60x-000 configuration provides different sensitivity values according to the selected electrical load and Harting pin connection.
|
Sensitivity values are specified at 20°C and 80 Hz. The nominal damping factor is approximately 0.7 at a 100 kΩ load.

07 / MOUNTING ORIENTATION
Vertical Measurement Axis
PR9268/601-000 is a PR9268/60x-000 vertical configuration. Its nominal measuring direction is vertical.
|
Without sinking current, the permitted deviation from the nominal vertical direction is ±30°. With sinking current, the sensor can accommodate a deviation up to ±60°. When installed away from the nominal measuring direction, measurement accuracy is reduced if the required sinking current is not applied.
|
|
08 / HAZARDOUS AREA
Intrinsic-Safety Configuration
|
PR9268/60(0–3)-000 configurations may be used in hazardous areas under the specified intrinsic-safety installation conditions. For the PR9268/60x-000 family, the permitted protection concept is intrinsic safety with ATEX and IECEx classifications subject to the applicable installation requirements.
Hazardous-area installation requires the specified safety barriers, field wiring practices, grounding arrangements and environmental limits. The armored versions PR9268/60(0–3)-000 are the permitted 60x-000 configurations for the stated hazardous-area application.

|
09 / SAME SERIES
PR9268 Family
The PR9268 family uses the same general electrodynamic velocity-sensing principle while offering different measurement directions, temperature ranges and cable configurations.

10 / CONFIGURATION LOGIC
Why /601-000 Matters
|
This configuration is particularly relevant when an existing installation requires a vertical PR9268 sensor with the higher-temperature 60x construction, a 5 m armored connection and a Harting interface. Matching these configuration details is important when replacing an installed sensor.

11 / FAQ
Purchase Questions
Key checks for replacement, compatibility and installation planning.
|
Why is Emerson PR9268/601-000 different from a standard PR9268/20x-x00 sensor when replacing a high-temperature installation?
PR9268/601-000 belongs to the 60x-000 high-temperature family. It uses a stainless-steel housing, operates from −20 to +200°C with short-time operation up to +220°C, and has a 10–1000 Hz frequency range. The standard PR9268/20x-x00 family is rated for a lower temperature range and uses a different 4–1000 Hz performance range. A replacement should therefore match the installed temperature class and measurement configuration rather than only the PR9268 family name.
What does the “601-000” configuration of Emerson PR9268/601-000 tell a buyer about the cable and connector?
The “60” identifies the vertical high-temperature measurement configuration, the “1” specifies a 5 m armored cable, and the final “0” before the family suffix specifies a Harting cable end. The 60x-000 design uses a six-pole Harting plug with an integrated resistor network. This configuration detail is important when the replacement must mate with an existing installation arrangement.
Can Emerson PR9268/601-000 be installed away from a perfectly vertical position?
The nominal measurement direction is vertical. The PR9268/60x-000 family permits a deviation of ±30° without sinking current and up to ±60° when sinking current is applied. Without the required sinking current, measurement accuracy is reduced for installations outside the nominal arrangement. This should be checked during replacement planning when the existing mounting location is not exactly vertical.
Which Emerson PR9268/601-000 sensitivity should be considered when checking an existing monitoring input?
At 20°C and 80 Hz, the specified sensitivity is 22.0 mV/(mm/s) ±5% at pin 3 with a 100 kΩ electrical load. The specification also gives 16.7 mV/(mm/s) ±5% at pin 1 with a 50 kΩ load and 16.7 mV/(mm/s) ±5% at pin 4 with a 20 kΩ load. The receiving circuit and its electrical load should therefore be checked before treating another PR9268 configuration as an interchangeable replacement.
Is Emerson PR9268/601-000 suitable for hazardous-area applications?
The PR9268/60(0–3)-000 configurations are covered by the stated intrinsic-safety provisions for hazardous areas when the specified installation conditions are met. The 60x-000 family is associated with ATEX II 2G Ex ib IIC T4/T3 Gb and IECEx Ex ib IIC T4/T3 Gb classifications. Installation requires the applicable safety barriers, field wiring, grounding and temperature restrictions; the connector temperature limit is 100°C even though the sensor body has the higher-temperature rating.
