- API 670 machinery protection systems
System Compatibility
The 330102-00-40-10-11-05 probe is designed to operate within the Bently Nevada 3300 XL Proximity Transducer System, which includes:
- Extension Cable: 330130-XX-XX (1 m or 5 m, matched to probe cable length)
- Driver / Oscillator-Demodulator: 330180-X1-05 / 330180-X1-CN (standard); 3300 XL 8 mm driver
- Monitor: 3300/16, 3500/40M, 3500/42M, 3500/45, 3500/46M (Bently Nevada 3500 rack)
- Power Supply: −24 VDC (nominal), supplied by monitor or external conditioner
Ensure total cable system length (probe + extension) matches the driver calibration (typically 5 m or 9 m total).
Selection Guide
Use the part number structure to select the correct variant:
330102 - 00 - [Cable Length] - [Thread] - [Cable Type] - [Approval]
8mm Standard 10=M10×1 11=Armored 05=CE/ATEX
Cable Length: 40=1.0m | 50=1.5m | 80=2.0m
Cable Type: 10=Standard | 11=Armored | 02=Metric connector
Approval: 05=CE/ATEX | 00=Standard
If your application requires a different cable length or approval rating, contact Konmask — we can source the exact variant.

Replacement & Compatibility FAQ
Q: Can I use a 330102-00-40-10-10-05 (non-armored) in place of the -11- (armored) variant?
A: Electrically identical. The only difference is cable construction. Use armored (-11-) in high-vibration or abrasive environments.
Q: Is the Epro PR6423/010-100 a direct drop-in replacement?
A: Yes, when paired with a compatible Epro driver. If using a Bently Nevada 330180 driver, gap voltage re-verification is required.
Q: What gap voltage should I set for this probe?
A: Nominal gap voltage is −10.0 VDC (corresponding to ~1.0 mm gap on AISI 4140 steel target). Refer to Bently Nevada TDI 141-109-000 for full calibration procedure.
Q: Can this probe be used with the Bently Nevada 3500 system?
A: Yes. The 3300 XL probe system is fully compatible with 3500 series monitors (3500/40M, 3500/42M, 3500/45, 3500/46M).
Q: Do you provide calibration certificates?
A: Yes. CoC and calibration data sheets are available for all units. Request at time of order.
