Emerson PR9268/617-100-CNS High-Temperature Velocity Sensor
A vertical high-temperature special version with a 10 m non-armored open-end cable and separately installed resistor network.
Product Identification
PR9268/617-100-CNS is a special Emerson PR9268 vertical high-temperature velocity sensor. The /61x-100-CNS configuration uses an open cable end and requires its resistor network to be installed separately.
The 7 cable code identifies a 10 m non-armored lead. The high-temperature sensing family operates from -20 to +200°C with a 10 to 1000 Hz frequency range.

Functions
- Supports vertical case-vibration measurement at sensor temperatures up to 200°C.
- Provides an open-end ten-meter lead for the CNS termination arrangement.
- Uses selectable output pins and defined load resistances for the required sensitivity.
- Separates the resistor network from the sensor assembly for the documented special version.
Applications
- Industrial drive and machinery-protection maintenance
- Configuration-controlled spare replacement
- Planned outage and reliability support
Lifecycle
- Retain the complete model, hardware revision, host equipment and removal photographs in the asset record.
- Keep the spare clean, dry and protected from electrostatic discharge, connector damage and cable deformation.
- Review current manufacturer lifecycle information and an approved migration path before a critical shutdown.
FAQ
PR9268/617-100-CNS: What must be included besides the sensor?
Confirm the separately installed resistor network, terminal hardware and any barrier or isolator required by the approved loop.
PR9268/617-100-CNS: Why are pin and load details essential?
The available sensitivity depends on the selected output pin and its specified load; an incorrect resistor network changes channel response.
PR9268/617-100-CNS: What photographs are useful for a CNS replacement?
Capture the sensor label, cable entry, terminal box, resistor-network values and wiring, barrier/isolator label, and monitor terminals.
PR9268/617-100-CNS: How should the ten-meter non-armored lead be protected?
Use the approved conduit, tray or other protection, maintain bend radius and temperature clearance, and prevent cable strain at the sensor.
PR9268/617-100-CNS: Can a standard PR9268/60x-000 with Harting plug replace it?
Not as a direct exchange. The open-end CNS wiring and separate resistor network require an engineering review of signal, termination and approvals.
PR9268/617-100-CNS: What commissioning measurements should be recorded?
Document resistor values, pin selection, loop resistance, polarity, channel scaling, noise floor, baseline vibration and alarm verification.
