Description
The 330800-28-00-085-02-02 PROXPAC XL Proximity Sensor Assembly is a high-precision industrial sensor designed for monitoring vibration and position in rotating machinery. Featuring an 8 mm 3300 XL probe with 85 mm length and 3/4-14 NPT mounting thread, it provides accurate output over a voltage range of –1 V to –17 V. 

The sensor supports long-distance wiring up to 305 meters (1,000 feet) with excellent frequency response and gain stability, making it ideal for industrial monitoring applications. Housed in a durable polyphenylene sulfide (PPS) enclosure with IP66/NEMA 4X protection, it can withstand extreme environmental conditions while maintaining reliable operation.

The Bently Nevada 330800‑28‑00‑085‑02‑02 is a high‑precision PROXPAC XL proximity transducer assembly designed for non‑contact vibration and shaft position monitoring in industrial rotating machinery condition monitoring systems. 

As part of the Bently Nevada 3300 XL Proximity Transducer System, this transducer provides accurate, real‑time measurement data used in predictive maintenance, machine protection, and reliability programs across industries such as power generation, oil & gas, petrochemical, and heavy manufacturing.
