Frequently Asked Questions

• What does the suffix "08" signify on the 21504-08-20-10-02?
  The "08" indicates an 80 mm unthreaded tip extension. This longer tip allows you to mount the probe further away from the target while keeping the electronics safe.
• Is this probe compatible with the 7200 monitor rack?
  Yes, this 21504-08-20-10-02 is designed specifically for the Bently Nevada 7200 Series monitoring systems and requires a compatible proximitor.
• What materials can this probe accurately measure?
  Bently Nevada calibrates these probes for AISI 4140 steel. Using different metals may require recalibration for accurate readings.
• Do you ship internationally, and how fast is delivery?
  Yes, we ship worldwide via FedEx, UPS, and DHL. We process all orders within 5 days of purchase.
