Selection Guide
Use the following criteria to confirm the PR6426/000-030 CON021/916-240 is the right choice for your application:
- Target material: Steel or iron shaft (non-ferrous targets require recalibration)
- Gap range required: 0.25 mm to 2.25 mm (optimal linear range)
- Probe diameter: 14 mm (M14 thread) — suitable for standard bearing housings
- Cable extension: Standard 1000 mm; extension cables available up to 9 m total
- Conditioner supply: –24 VDC required; confirm power supply availability
- Monitoring system: Must accept –24 VDC Bently Nevada-standard signal
If your application requires a different gap range, probe diameter, or target material, refer to the compatible models listed above or contact our technical team.

Replacement & Compatibility FAQ
Q: Can I use the PR6426/000-030 with a Bently Nevada 3500 rack?
A: Yes. The CON021/916-240 conditioner outputs a –24 VDC standard signal fully compatible with Bently Nevada 3500 series input cards.
Q: What is the difference between PR6426 and PR6423?
A: The PR6426 uses a 14 mm probe body; the PR6423 uses an 8 mm body. Both share the same output standard but differ in gap range and installation clearance requirements.
Q: Can I replace just the probe without replacing the conditioner?
A: Probe and conditioner are factory-matched. Replacing only one component may affect calibration accuracy. Always replace as a matched pair unless recalibration is performed.
Q: Do you provide calibration certificates?
A: Yes. Calibration certificates are available upon request for all units shipped from Konmask.com.
Q: What is the lead time for this model?
A: Standard stock items ship within 3–5 business days. Contact us for current availability.
