EPRO PR9268/302-100 Electrodynamic Velocity Sensor | Horizontal Vibration Sensor

EPRO PR9268/302-100 is a high-performance electrodynamic velocity sensor from EPRO (Emerson AMS), designed for absolute casing vibration measurement on critical rotating machinery. This model belongs to the PR9268/30x series, built specifically for horizontal mounting with ±10° installation tolerance, widely used in turbomachinery protection and condition monitoring systemsEmerson.

As a passive seismic velocity transducer, PR9268/302-100 generates an output voltage signal directly proportional to vibration velocity, no external excitation power required. Its working principle relies on a seismic mass and coil assembly suspended by membrane springs, operating above the natural resonance frequency at 4.5 Hz, which enables stable and reliable vibration pickup from bearing housings and equipment casings.

The frequency response of EPRO PR9268/302-100 covers 4 Hz to 1000 Hz, supporting peak-to-peak vibration amplitude up to 3000 μm. Low-impedance coil design delivers strong anti-interference capability, the raw vibration signal can feed directly into EPRO MMS3000, MMS6000 monitoring racks without extra pre-amplifier, which simplifies system wiring and reduces signal loss in industrial field installation.

Housing material is Al Mg Si alloy, protection class IP55, rated for non-condensing humidity 0–100%. Standard cable is PTFE insulated 3×0.5mm² with stainless steel armor, terminated with Harting connector. Net weight of PR9268/302-100 is 930g, rugged construction withstands vibration, dust and splash in power plant, oil & gas and heavy process industry environments.

Typical applications of EPRO PR9268/302-100: steam turbine, gas turbine, hydro turbine, centrifugal compressor, axial fan, boiler feed pump, gearbox, coal mill and other critical rotating equipment. It monitors casing vibration continuously to detect unbalance, misalignment, loose support and bearing degradation, supporting machinery protection trip and predictive maintenance workflowsEmerson.

Differences to help your selection: PR9268/20x series is for vertical mounting; PR9268/30x including PR9268/302-100 is horizontal type; PR9268/60x /70x are high-temperature variants with wider angle tolerance. This model is frequently paired with EPRO signal conditioners and rack-based vibration monitoring modules as a complete machine protection solutionEmerson.

We supply original EPRO PR9268/302-100 vibration velocity sensor, genuine stock available. We can provide datasheet, COO certificate, test report and 12-month warranty. For bulk inquiry, cross check compatibility with your existing MMS3000 / MMS6000 system, or matching accessories and spare connectors, send us your request.
