• Pressure sealing : Viton O‑ring (differential design, not tested before shipment)
• Weight : approx. 14 to 150 g (0.5 to 5.3 oz)

Frequently asked questions

• Can I use this probe with a 3300 XL extension cable?
  Yes, the 3300 NSv Proximity Probes series mates directly with the 3300 XL 8mm Probe cables via the ClickLoc connector.
• What is the difference between suffix 01 and 02 connector?
  Suffix 01 includes a connector protector for added durability, while suffix 02 is the standard ClickLoc without protector.
• Does the probe withstand high pressure?
  It seals differential pressure with a Viton O‑ring, but we do not pressure‑test every unit before shipping.
• Is the 75 Ω impedance critical?
  Absolutely – the NSv Proximity Probes require 75 Ω coaxial cable to maintain signal integrity with Bently Nevada monitors.
