Product Abstract
The 330880-28-15-027-00-02 is an all-in-one PROXPAC XL Proximity Transducer system. It integrates a 3300 XL 8mm probe and a Proximitor sensor into a single, high-durability thermoplastic housing. This model features a 1.5-inch standoff and 27mm penetration, designed to simplify installation while providing precise vibration and position data for critical rotating machinery in hazardous areas.
Oiltech Controls Limited’s Insight
The 330880-28-15-027-00-02 is a masterclass in field engineering. By housing the electronics at the measurement point, it eliminates failure points from long extension cables. The UV-resistant PPS housing is exceptionally durable in offshore environments where metal might corrode. Our data shows that the 3/4-14 NPT mounting provides a leak-proof interface, while the silicone isolation prevents false vibration signals caused by housing resonance.

Professional FAQ & Selection Guide
- Question: What is the benefit of the PPS thermoplastic housing?Answer: It is immune to rust and highly resistant to UV and chemical corrosion, making it superior to aluminum in coastal or offshore plants.
- Question: How is total probe reach calculated for the 330880-28-15-027-00-02?Answer: Reach is the sum of the Standoff (1.5″) and Penetration (27mm). Ensure your port depth allows for the 1.27mm (50 mil) target gap.
- Question: Can I use field wiring longer than 300 meters?Answer: Max distance is 305 meters (1,000 ft). Longer runs cause high-frequency signal rolloff.
- Question: What if the gap voltage is more positive than -1 Vdc?Answer: This typically indicates an “over-gap” condition or the shaft target size is smaller than the 15.2mm minimum.
- Question: Why is the 3/4-14 NPT thread mandatory for this model?Answer: The -02 thread provides the structural strength required to support the standoff adapter and housing assembly safely.
