Bently Nevada 330105-02-12-10-02-05 8mm Probe

Bently Nevada 330105-02-12-10-02-05 3300 XL 8mm Reverse Mount Probe

Product Introduction

The Bently Nevada 330105-02-12-10-02-05 is a high-performance reverse mount proximity probe from the industry-standard 3300 XL series. This model is configured with 3/8-24 UNF threads and a 1.0-meter total length option, offering flexibility for various installation requirements. It includes a miniature ClickLoc coaxial connector for a secure and reliable connection.

This 3300 XL 8 mm probe delivers accurate, linear measurements of shaft vibration and position in critical turbomachinery. Its construction uses PPS for the tip and AISI 303/304 stainless steel for the case, ensuring durability. Moreover, the 330105-02-12-10-02-05 features multiple agency approvals including CSA, ATEX, and IECEx, making it suitable for installations in potentially explosive atmospheres.

Technical Specifications

Electrical and Range Parameters
The Bently Nevada 330105-02-12-10-02-05 uses a 75Ω triaxial FEP-insulated cable for signal transmission. The nominal probe DC resistance from the center conductor to the outer conductor is 7.59 ± 0.50 ohms for its 1.0-meter length. Furthermore, it provides a linear range consistent with the 3300 XL 8 mm probe family, ensuring reliable data for machine protection and condition monitoring systems.

Mechanical and Material Details
The probe tip is constructed from Polyphenylene sulfide (PPS), while the case uses either AISI 303 or 304 stainless steel (SST). The connector features gold-plated brass or beryllium copper construction for excellent signal integrity. The maximum length of thread engagement for the 3/8-24 thread is 0.563 inches, and the cable has a maximum rated tensile strength of 330 N at the case-to-lead junction.

Environmental and Operating Conditions

Temperature, Humidity, and Pressure Ratings
This standard 3300 XL probe operates and stores safely within a temperature range of -52°C to +177°C (-62°F to +350°F). However, exposing the probe to temperatures below -34°C (-30°F) for extended periods may lead to premature failure of the pressure seal. Additionally, the probe exhibits less than a 3% change in Average Scale Factor when tested in 93% relative humidity for up to 56 days, per IEC 68-2-3 standards. The probe uses a Viton O-ring to seal differential pressure between the tip and the case.

Installation Guidelines

Mounting and Connection
Installing the 330105-02-12-10-02-05 requires attention to proper threading and torque. First, thread the probe into the mounting hole by hand to ensure correct alignment. Then, tighten it to the recommended torque specification. Finally, connect the miniature ClickLoc connector by pushing it until it audibly clicks, confirming a secure, locked fit that prevents loosening from vibration.

Cable and Wiring Considerations
The probe uses a 75Ω triaxial FEP-insulated cable as standard. For applications requiring higher temperatures, an extended temperature range PFA cable is available. The maximum tensile strength at the probe lead to extension cable connectors is 270 N (60 lbf). Meanwhile, for optimal signal integrity and system performance, ensure all connections remain clean and properly secured.
