Frequently Asked Questions

• What is the maximum cable length available for 3300 5mm probes?
  Bently Nevada offers total probe lengths of 0.5, 1.0, 2.0, 5.0, or 9.0 meters. Model 330171-00-20-90-02-05 features a 9.0-meter cable for remote installations.
• What applications suit the 9.0-meter cable length?
  This extended cable works well when the proximity system must be located far from the measurement point, such as in large machinery installations or control room setups.
• What torque specifications apply to 1/4-28 threaded probes?
  Use 5.1 N•m (45 in•lb) recommended torque. Maximum torque is 7.3 N•m (65 in•lb) to prevent thread damage. A #3 or larger tap drill is recommended for mounting hole preparation.
• What is the operating temperature range for this probe?
  The probe operates from -35°C to +177°C (-31°F to +351°F). Sustained exposure below -34°C may cause premature pressure seal failure.
• 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.
