Bently Nevada Proximity Transducer | 330881-28-05-080-00-02

Overview

The Bently Nevada 330881-28-05-080-00-02 PROXPAC XL Proximity Transducer Assembly is a robust and self-contained proximity probe system designed to provide high reliability in severe industrial environments. This assembly integrates the 3300 XL 8 mm proximity probe and its corresponding Proximitor sensor into a single housing, eliminating the need for an extension cable and a separate Proximitor housing. The housing is constructed from advanced Polyphenylene Sulfide (PPS), offering superior strength and protection, including electrostatic charge dissipation and high durability against harsh conditions. It is rated for IP66 and Type 4X environments.

Key Features:

• Self-contained design: Combines proximity probe and Proximitor sensor into one housing.
• Material: Made of Polyphenylene Sulfide (PPS) for high strength and electrostatic protection.
• Ease of installation: Direct field wiring between monitors and assembly.
• IP66 and Type 4X rated: Ideal for harsh environments.
• Includes 3300 XL 8mm probe: With multiple approvals for versatile applications.
