Compatible Replacement & Equivalent Models
The following models are commonly evaluated as direct or functional replacements for the PR9268/300-000. Always verify electrical and mechanical compatibility before substitution.
| Model | Manufacturer | Compatibility Notes |
|---|---|---|
| PR9268/200-000 | Epro | Same series, 200 mm cable — verify cable length requirement |
| PR9268/500-000 | Epro | Same series, 500 mm cable — drop-in if cable length acceptable |
| CS-1 / CS-2 | Bently Nevada | Functional equivalent; check connector and sensitivity match |
| VS-068 | Metrix (SKF) | Similar frequency range; confirm output impedance |
| 8200 Series | Wilcoxon Sensing | Piezoelectric alternative; requires signal conditioning change |
| VM-2000 | Hansford Sensors | Electrodynamic equivalent; verify mounting thread |

Why Choose the Original Model
- OEM-grade reliability — manufactured to Epro’s industrial quality standards for 24/7 continuous monitoring
- Proven field performance — widely deployed in turbines, compressors, pumps, and generators globally
- Direct system compatibility — plug-and-play with Epro CON021, CON041, and compatible Bently Nevada monitors
- Passive coil design — no external power required; inherently fail-safe signal output
- IP67 protection — suitable for harsh industrial environments with moisture and dust exposure
Typical Applications
- Steam and gas turbine bearing vibration monitoring
- Centrifugal compressor casing velocity measurement
- Pump and motor vibration surveillance
- Gearbox and fan vibration trending
- Condition monitoring systems in power plants and petrochemical facilities
System Compatibility
The PR9268/300-000 is designed for direct integration with the following monitoring systems:
- Epro CON021 — Dual-channel vibration monitor
- Epro CON041 — Rack-mount vibration monitoring module
- Bently Nevada 3500 Series — With appropriate input card configuration
- Bently Nevada 1900/65 — General-purpose machinery protection
- Generic 4–20 mA or voltage-input vibration monitors (with signal conditioner)
Selection Guide
Use the following criteria to confirm the PR9268/300-000 is the right sensor for your application:
- Cable length: Requires 300 mm integral cable — if longer runs are needed, select PR9268/500-000 or use extension cable
- Frequency range: Suitable for 10–1000 Hz; for sub-10 Hz low-speed machinery, consider a proximity probe instead
- Mounting orientation: Radial or axial — confirm machine geometry and available mounting boss
- Temperature: Rated to 120°C; for higher-temperature zones (e.g., near exhaust), specify high-temp variant
- Signal type: Passive coil output — confirm monitor input accepts passive velocity sensor (not IEPE/ICP)

Replacement & Compatibility FAQ
Q: Can the PR9268/300-000 replace a Bently Nevada CS-1 sensor?
A: Functionally similar, but connector type and sensitivity may differ. Engineering verification is required before substitution.
Q: Is this sensor compatible with IEPE (ICP) inputs?
A: No. The PR9268/300-000 is a passive electrodynamic sensor. It is not compatible with IEPE/ICP-powered inputs without a signal conditioner.
Q: What is the difference between PR9268/200-000, PR9268/300-000, and PR9268/500-000?
A: The suffix (200/300/500) denotes the integral cable length in millimeters. All other specifications are identical.
Q: Can I use this sensor for axial and radial measurements?
A: Yes, the PR9268/300-000 supports both radial and axial mounting orientations depending on the machine configuration.
Q: Do you offer expedited shipping for urgent plant shutdowns?
A: Yes. Contact us directly at support@konmask.com or +0086 19859288691 for emergency sourcing support.
