Technical Specifications – Bently Nevada 330101-00-70-10-02-00

• Linear range: 2 mm (80 mils) — from 0.25 mm to 2.3 mm (10 to 90 mils). This corresponds to -1 Vdc to -17 Vdc output.
• Incremental Scale Factor (ISF): 7.87 V/mm (200 mV/mil) ±5% for 1.0 m system. We measure this over 0°C to +45°C in 0.25 mm increments.
• Probe DC resistance (RPROBE): 7.59 Ω ±0.50 for 1.0 meter probe length. This measurement runs from center conductor to outer conductor.
• Recommended radial vibration gap: Set to -9 Vdc, approximately 1.27 mm (50 mils) from target surface.
• Deviation from best fit straight line (DSL): Less than ±0.025 mm (±1 mil) for 1.0 m system at 0°C to +45°C.
• Extension cable capacitance: 69.9 pF/m (21.3 pF/ft) typical.
• Temperature range (standard probe): Operating and storage from -52°C to +177°C (-62°F to +350°F). Note: Avoid below -34°C to preserve pressure seal integrity.
• Probe tip material: Polyphenylene sulfide (PPS) with thicker encapsulation for ruggedness.
• Probe case material: AISI 303 or 304 stainless steel.
• Weight: 323 g/m (11.4 oz/ft).
• Relative humidity withstand: Less than 3% Average Scale Factor change after 56 days at 93% humidity (IEC 68-2-3).
• Pressure sealing: Viton® O-ring seals differential pressure between probe tip and case.

Frequently Asked Questions

• What does unthreaded length 00 mean for installation?
  00 option means zero unthreaded length — the probe tip mounts flush with the mounting surface. This suits applications requiring minimal tip protrusion.
• What is the difference between standard and extended temperature range?
  Standard probes operate from -52°C to +177°C. Extended range tips survive up to +218°C with cable to +260°C.
• Can I use this 1.0 m probe with a 9 m extension cable?
  Yes, but expect ISF ±6.5% and DSL up to ±0.038 mm over temperature range.
• Does the 330101-00-70-10-02-00 include probe armor?
  No, this version comes without armor. Order armored version separately if needed.
• What tools does installation require?
  Standard 3/8-24 UNF tap and torque wrench following Bently Nevada manual specifications.
• Is this probe compatible with existing 3300 XL extension cables?
  Yes, it uses the standard miniature coaxial ClickLoc connector interface.
