Description
The Epro PR9268/201-100, also cataloged as the PR9268/201-100 Electrodynamic Velocity Sensor, operates as a dedicated hardware component for precise vertical vibration velocity measurement within turbomachinery protection platforms. Operating across turbines, compressors, and pump sets, this sensor measures low-frequency absolute mechanical vibration for continuous condition monitoring.

4-20 mA HART Loop Protocol & Channel Isolation
The Epro PR9268/201-100 generates a self-powered AC millivolt output proportional to dynamic casing vibration. To maintain signal integrity across connected monitoring systems, receiving signal conditioning hardware utilizes channel-to-channel isolation. This isolation suppresses common-mode electrical noise and eliminates ground loop corruption across 4-20 mA HART loop protocol networks during continuous operation.
Frequently Asked Questions
Q: What is the primary physical orientation design for the PR9268/201-100 velocity sensor?
A: The sensor is specifically designed for precise absolute vibration velocity measurements in the vertical direction.
Q: Does the PR9268/201-100 require external DC power for signal generation?
A: No. As an electrodynamic low-frequency transducer, it functions as a self-generating passive sensor producing an AC voltage output.
Field Installation Guidelines
- Verify that the mounting face on the bearing housing is clean, flat, and tapped perpendicular to the vertical axis.
- Mount the PR9268/201-100 sensor vertically, ensuring mechanical mounting stud engagement conforms to cabinet structural standards.
- Inspect the stainless steel housing and PTFE integral cable for physical damage or sharp bends prior to final positioning.
- Route the cable through grounded conduit, ensuring lateral acceleration exposure remains well under the 2g limit.
- Terminate overall cable shielding at a single point on the monitor panel ground bar to maintain noise suppression performance.
