System compatibility:Matches EPRO MMS6000 TSI rack system,works with MMS3120 / MMS6220 monitor modules,for steam turbine,compressor,fan and pump bearing housing absolute vibration monitoring.

Function:Electrodynamic velocity sensor,directly detect bearing housing absolute vibration.Convert mechanical vibration into analog AC voltage signal,transmit signal to TSI monitor for vibration amplitude calculation,alarm and machinery fault diagnosis.

Installation:Vertical mounting on bearing housing surface.Connect signal cable to MMS series vibration monitoring module terminal.

Interface:

‑Open cable end for user wiring

‑Internal moving coil measuring element

‑Stainless steel threaded sensor body

Circuit feature:Built-in moving coil structure,no external power supply required,good low-frequency response,shock and oil resistant for harsh industrial environment.

Feature:EPRO PR9268 vibration sensor,/20=vertical mount,0=no prefabricated cable,000=cable free end. User needs to prepare shielded cable on site. Common faults:internal coil fracture,connector wiring error,mechanical damage. Confirm mounting direction before replacement.

Diagnostic:Sensor fault causes missing vibration signal,loss of bearing vibration reading,trigger TSI vibration alarm.

Built‑in function

PR9268/200-000 measures bearing housing absolute vibration for rotating machinery protection,widely used for power plant TSI spare replacement.

Product Brief

PR9268/200-000 belongs to EPRO electrodynamic velocity sensor family,vertical mount absolute vibration probe without pre-made cable. Verify mounting orientation and monitor module compatibility before ordering. Check coil resistance and signal output function during commissioning. Widely applied for steam turbine,compressor,fan and pump condition monitoring. ESD anti‑static protection shall be followed during installation.
