Frequently Asked Questions

• What is the maximum cable length available for 3300 NSv probes?
  Bently Nevada offers total probe lengths of 0.5, 1.0, 5.0, or 7.0 meters. Model 330901-20-32-10-02-05 features a 1.0-meter cable.
• What applications suit the 2.0-inch unthreaded length?
  This longer unthreaded section works well when the probe needs to extend beyond the mounting boss before reaching the target surface.
• What torque should I apply to avoid damaging the probe case?
  Use 11.3 N•m (100 in•lb) for standard mounting. For the first three threads, apply 7.5 N•m (66 in•lb) to prevent thread deformation.
• How do I select the correct probe for deep mounting holes?
  Consider overall case length plus unthreaded length. This model offers 3.2-inch case with 2.0-inch unthreaded section, ideal for deeper mounting configurations.
• What does the multiple approvals option include?
  Agency approval option 05 provides certifications for hazardous area installations. Consult Bently Nevada documentation for specific approval details.
