Bently Nevada 330196-05-30-10-CN 3300 XL ETR Reverse Mount Proximity Probe

Description

330196-05-30-10-CN is a 3300 XL 8 mm Extended Temperature Range (ETR) reverse mount proximity probe featuring a metric M10 x 1 thread, an unthreaded length of 5.0 mm (Option 05), an overall case length of 30 mm (Option 30), a total probe length of 1.0 meter (Option 10), and the CN China hazardous area approval package. This specific sensor configuration is designed to perform in environments where the probe cable and connector are exposed to temperatures up to 260 degC and the probe tip up to 218 degC, transcending the limits of standard proximity probes.

The reverse mount configuration allows the probe to be installed through a mounting sleeve or housing, simplifying replacement and maintenance on industrial machinery. This probe operates within the 3300 XL eddy-current transducer system, which is used for both static gap (axial position) and dynamic vibration measurements. By pairing with a compatible 3300 XL Proximitor Sensor and extension cable, it translates the physical distance between the probe tip and the observed conductive surface into a directly proportional analog voltage output.

Features

• Extended temperature range design with a rating of -52 degC to +218 degC for the probe tip and -51 degC to +260 degC for the probe cable and connector.
• Reverse mount installation style with M10 x 1 thread, enabling external access and adjustment within sleeves or machinery housings.
• Unthreaded case portion of 5.0 mm and threaded case portion of 30 mm for structured mounting depth.
• Integrated 1.0-meter triaxial cable insulated with perfluoroalkoxy (PFA) for signal integrity under chemical and thermal exposure.
• Miniature male coaxial ClickLoc connector providing a secure connection with positive feedback and backward compatibility with standard extension cables.
• China hazardous area approval package (-CN) including CCC and NEPSI certifications for safe operation in explosive environments.

Applications

This reverse mount ETR proximity probe is suitable for industrial machinery protection and condition monitoring in hazardous or high-temperature environments. Typical applications include:

• Radial vibration and axial position measurements on steam and gas turbines with high casing temperatures.
• Shaft vibration and oil film bearing clearance monitoring on large industrial pumps and compressors.
• Keyphasor reference and speed measurement on high-speed rotating machinery.
• Machinery monitoring in environments demanding NEPSI and CCC safety markings in China.

Installation Guidelines

To ensure proper performance and mechanical integrity when installing the 330196-05-30-10-CN probe, follow these guidelines:

• Reverse Mounting: Thread the probe body through the reverse mount sleeve or bracket until the probe tip is positioned at the required gap from the target surface.
• Maximum Thread Engagement: Do not exceed the maximum rated thread engagement of 15 mm to avoid binding or damage to the metric M10 x 1 threads.
• Tightening Torque: Apply the recommended torque for reverse-mount probe cases: 7.5 N-m (66 in-lbf) standard, up to a maximum rated torque of 22.6 N-m (200 in-lbf).
• Cable Routing and Bend Radius: Maintain a minimum cable bend radius of 25.4 mm (1.0 in) along the run. Ensure the triaxial PFA-insulated cable is secured with clamps to prevent whipping or mechanical wear.
• Connector Assembly: Secure the ClickLoc connector finger tight during installation. Avoid using tools on the coaxial connectors unless specifically adapting non-XL components.
