Bently Nevada Proximity Transducer | 330881-28-00-110-03-02

Overview

The Bently Nevada 330881-28-00-110-03-02 PROXPAC XL Proximity Transducer Assembly is a self-contained system designed to provide high-precision proximity measurements. It integrates a 3300 XL 8 mm proximity probe with a built-in 3300 XL Proximitor sensor, eliminating the need for a separate Proximitor housing. This assembly is ideal for monitoring applications in extreme environments, offering reliable protection and performance.

Features:

• Integrated Design: No need for an extension cable or a separate Proximitor housing.
• Durability: The housing is made from Polyphenylene Sulfide (PPS), a thermoplastic that enhances strength and electrostatic charge dissipation.
• Environmentally Rated: Type 4X and IP66 for protection against harsh environments.
• Sensor Integration: Direct connection of field wiring to monitors via the PROXPAC XL housing.
