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 armored signal cable Harting plug to MMS series vibration monitoring module terminal.

Interface:

‑Stainless steel armored 8m PTFE integrated cable

‑Harting heavy duty connector for signal output

‑Internal moving coil measuring element

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

Feature:EPRO PR9268 series absolute vibration sensor,/20=vertical mount,2=8m armored cable,-100=Harting connector.Used for casing vibration measurement. Common faults:cable armor damage,internal coil fracture,connector pin corrosion. Confirm mounting direction before replacement.

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

Built‑in function

PR9268/202-100 measures bearing housing absolute vibration for rotating machinery protection,widely used for power plant TSI spare replacement.

Product Brief

PR9268/202-100 belongs to EPRO electrodynamic velocity sensor family,vertical mount 8m armored cable vibration probe with Harting connector. Verify mounting orientation and monitor module compatibility before ordering. Check coil resistance and waveform output during commissioning. Widely applied for steam turbine,compressor,fan and pump condition monitoring. ESD anti‑static protection shall be followed during installation.
