Installation Guidelines
-
Mounting: Install the probe in a rigid bracket or housing that allows for precise adjustment. Use a sliding bracket for applications involving significant differential thermal expansion.
-
Gapping: The ideal gap between the probe tip and the target (AISI 4140 steel) is 1.27 mm (50 mils).
-
Calibration: When gapped correctly, the system should yield an initial output of approximately -9 V DC.
-
Linear Range: The system operates linearly between 0.25 mm and 2.3 mm (10 to 90 mils).
-
Handling: Ensure the probe tip is protected from mechanical impact during installation. Avoid sharp bends in the coaxial cable to maintain signal integrity.
FAQs
What is the 330101-00-77-15-02-CN?
It is a specific configuration of the 3300 XL 8 mm Proximity Probe used to monitor vibration and position in critical rotating machinery.
How does the probe measure vibration?
The probe utilizes the eddy current principle to measure the gap between the probe tip and a conductive shaft, converting this distance into a proportional voltage signal for both static and dynamic analysis.
Is this probe interchangeable with older systems?
Yes, 3300 XL 8 mm components are both electrically and physically interchangeable with non-XL 3300 5 mm and 8 mm components, provided the mounting space and cable bend radius requirements are met.
