Product Technical Description
The 330100-90-01 proximity probe operates on the eddy current measurement principle. When installed near a conductive target such as a rotating shaft, the probe generates a high-frequency electromagnetic field. Changes in the distance between the probe tip and the target alter the eddy current field, producing a proportional voltage output.
This probe is engineered for long-term stability, ensuring consistent measurement accuracy even in high-temperature, high-vibration environments. When paired with the correct 3300 XL extension cable and proximity driver, it forms a fully calibrated measurement system capable of delivering reliable real-time data for machine protection and predictive maintenance.
Frequently Asked Questions (Q&A)
Q1: Can the 330100-90-01 be used alone?
A1: No. It must be used together with a compatible 3300 XL extension cable and proximity driver to form a complete measurement system.
Q2: What type of machinery is this probe suitable for?
A2: It is suitable for turbines, compressors, pumps, motors, and other critical rotating equipment.
Q3: Is the probe resistant to harsh environments?
A3: Yes. The stainless-steel housing and robust design allow operation in high-temperature and industrial environments.
Q4: Does cable length affect measurement accuracy?
A4: The probe is factory designed to work accurately with specified cable lengths when matched with compatible system components.
Q5: Can it measure axial position as well as vibration?
A5: Yes. Depending on installation, it can be used for both radial vibration and axial position measurements.
