Selection Guide
Use the table below to select the correct 3500/40 variant for your application:
- Radial vibration (proximity probe): → 3500/40-01-00 ✓
- Velocity measurement (Velomitor): → 3500/40-01-00 ✓
- Axial position only: → Consider 3500/45-01-00
- High-temperature environment (>65 °C): → Consult Emerson for special-order variants
- SIL-rated application: → Verify SIL certification with Emerson; 3500/40 is not inherently SIL-rated
- Replacement for failed module: → Confirm -01-00 vs -01-01 suffix; both are compatible in standard racks

Replacement & Compatibility FAQ
Q: Can 3500/40-01-01 replace 3500/40-01-00 directly?
A: Yes, in most standard 3500 racks the -01-01 revision is a drop-in replacement. Verify rack firmware version compatibility before installation.
Q: Is the 3500/40-01-00 compatible with older 3300 Series racks?
A: No. The 3500/40 is designed exclusively for the 3500 Series rack architecture and is not backward-compatible with 3300 Series racks.
Q: Can I use a third-party proximity probe with this monitor?
A: The module is optimized for Bently Nevada Proximitor sensor chains. Third-party probes may require sensitivity and gap voltage verification. Contact us for application support.
Q: Do you provide a warranty?
A: Yes. Konmask.com provides a 90-day functional warranty on all modules. Extended warranty options available on request.
Q: Can you provide a certificate of conformance?
A: Yes, available upon request for qualified B2B orders.
