Replacement & Compatibility FAQ
Q: Can I use PR6426/010-030 with a Bently Nevada 3500 rack?
A: Yes, when paired with the CON021/916-160 conditioner, the output is compatible with Bently Nevada 3500 series proximity input modules.
Q: What is the difference between PR6426 and PR6423?
A: PR6423 is an 8mm probe; PR6426 is also 8mm but with a different connector and cable configuration. Both use CON021 conditioners but verify suffix codes for exact compatibility.
Q: Is a replacement conditioner required when replacing the probe?
A: Not necessarily. If the existing CON021 conditioner is functional, only the probe needs replacement. Always re-calibrate the gap voltage after probe replacement.
Q: Do you supply calibration certificates?
A: Yes, calibration documentation is available upon request. Contact us before ordering to arrange.
