System Compatibility Notes

• Specifications apply to 3300 5 mm systems including Proximitor Sensor, extension cable, and probe.
• Performance characteristics apply only to systems with 3300 XL components.
• Calibration uses AISI 4140 steel target between +18°C and +27°C with -24 Vdc supply and 10 kΩ load.
• Critical: The 5.0 meter probe 146054-08-50-00-00 works exclusively with the 5.0 meter Proximitor Sensor.
• System accuracy and interchangeability specifications require AISI 4140 steel target.

Installation Guidelines

• Mount the probe using the 3/8-24 UNF thread with maximum engagement of 0.563 inches.
• This configuration has no connector – terminate the bare cable according to your installation requirements.
• Use proper cable termination techniques for 75 Ω coaxial cable.
• Verify the system uses matching 5.0 meter probe 146054-08-50-00-00 and 5.0 meter Proximitor Sensor.
• Ensure the target material matches AISI 4140 steel for specified accuracy.
• This configuration is for non-hazardous areas only (no agency approvals).
• Contact Bently Nevada for high-pressure applications exceeding 34 Bar.

Frequently Asked Questions

• What does the part number 146054-08-50-00-00 represent?
  146054 is the base model (3300 ceramic probe, 3/8-24 thread), 08 is 0.8" case length, 50 is 5.0m cable, 00 is no connector, and 00 is no agency approvals (non-hazardous).
• Can I use this 5.0 meter probe with any Proximitor?
  No, this 146054-08-50-00-00 5.0 meter probe requires a matching 5.0 meter Proximitor Sensor for proper system calibration. This is a critical compatibility requirement.
• What is the advantage of the "no connector" option?
  The bare cable allows you to terminate directly in junction boxes or custom applications, reducing connection points and potential failure points.
• Is this probe suitable for hazardous areas?
  No, the -00 agency option means this configuration has no hazardous area approvals. Use for non-hazardous locations only.
• What temperature range can this probe withstand?
  The probe operates and stores safely from -51°C to +177°C (-60°F to +351°F).
