Frequently asked questions

• What is the maximum cable length?
  Total probe lengths available are 0.5, 1, 5, or 7 metres – this model is the 1 m version.
• 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 3300 NSv Proximity Probe requires 75 Ω coaxial cable to maintain signal integrity with Bently Nevada monitors.
