Features:
- Electrodynamic spring-mass sensing for absolute vibration velocity in the horizontal direction
- The ordering code provides a 5 m armored cable for protected fixed routing
- An open cable end supports connection to the specified measuring and protection circuit
Emerson PR9268-301-100 converts housing vibration into an electrical signal without an external excitation supply.
The horizontal configuration must be installed within the official angular limits so gravity acts on the spring-mass system as intended.
Confirm the mounting plane, signal polarity, cable route, electrical load, machine frequency range, environmental limits, and hazardous-area circuit before commissioning.
Availability, condition, price, and shipping time for PR9268-301-100 are confirmed during quotation.

- Code 30 identifies the horizontal-measurement configuration
- The sensor base must be fastened to a rigid, flat machine surface
- Signal polarity follows the arrow and terminal identification in the installation guide
- The recommended maximum lifting or sinking current for permitted angular deviation is 1.8 mA.
- Measuring-circuit inductance is below 90 mH.
- Insulation resistance is greater than 1 MΩ at a 500 V AC test voltage.
- Intrinsically safe installations require the approved safety-barrier circuit.
- The metal cable-protection hose must be connected to protective earth with metal clamps.
- In Zone 0, protect the sensor housing against possible impact or friction sparks.
- Monitor horizontal case vibration on steam, gas and hydro turbines with PR9268-301-100
- Measure horizontal bearing-housing vibration on compressors and pumps
- Provide velocity-based protection input for fans and other critical rotating machinery
