Product Introduction

• The 330880-16-00-025-03-02 is a premium PROXPAC XL Proximity Transducer assembly.
• It integrates a 3300 XL 8mm probe into a rugged, glass-reinforced PPS thermoplastic housing.
• This system provides high-accuracy displacement and vibration data for critical rotating machinery.
• The IP66-rated enclosure protects internal components from UV, moisture, and chemical exposure.
• Engineers should download the full technical datasheet to verify mounting clearances and NPT seal steps.

Frequently Asked Questions

• Question: Why is the housing made of thermoplastic instead of aluminum?

  Answer: Glass-reinforced PPS provides superior UV and chemical resistance, making it ideal for harsh refineries.

• Question: Can I use this system for a shaft smaller than 50.8 mm?

  Answer: No, smaller diameters cause target curvature error, which leads to inaccurate vibration readings.

• Question: Does this probe require a specific Proximitor sensor?

  Answer: Yes, it is calibrated for use with the 3300 XL Proximitor series.

• Question: What if I need to mount this in a sub-zero environment?

  Answer: It is rated to -51 °C, but avoid mechanical stress below -34 °C to protect the pressure seal.

• Selection Guide: Always verify your “C” dimension (25mm) against your machine’s port depth to ensure the tip reaches the target.
