Bently Nevada 330701-00-30-90-02-00 Probe Sensor

Bently Nevada 3300 XL 11mm Proximity Probe 330701-00-30-90-02-00

Product Introduction

The Bently Nevada 330701-00-30-90-02-00 is a high-quality eddy current probe. It belongs to the globally recognized 3300 XL series, which is synonymous with dependable machinery protection. This sensor provides non-contact measurement of shaft vibration, thrust position, and eccentricity. Therefore, it plays a vital role in safeguarding turbomachinery such as steam turbines, gas turbines, and large compressors. Additionally, its robust construction ensures stable operation in harsh industrial environments. The probe outputs a linear voltage signal. This signal accurately reflects the gap between the probe tip and the monitored surface.

Technical Specifications

The configuration of the 330701-00-30-90-02-00 is precisely defined by its model number. The base "330701" indicates a 3300 XL 11 mm Probe with a 1/2-20 UNF thread and no armor. The "00" option denotes an unthreaded length of 0.0 inches. The "30" specifies an overall case length of 3.0 inches, which is longer than standard options for specific mounting depths. The "90" option signifies a total cable length of 9.0 meters, equivalent to 29.5 feet. Furthermore, the connector option "02" includes a miniature coaxial ClickLoc connector with a standard cable. Finally, the "00" agency approval indicates no specific certification is required.

Moreover, the materials used ensure durability and consistent signal integrity. The probe tip is constructed from Polyphenylene sulfide (PPS). The probe case uses AISI 304 stainless steel (SST). The cable is a 75 Ω triaxial type with fluoroethylene propylene (FEP) insulation. The DC resistance from the center conductor to the outer conductor is 8.5 ± 1.1 ohms. This low resistance ensures minimal signal loss. The probe case thread is 1/2-20, with a maximum thread engagement length of 0.750 inches.

Environmental and Mechanical Parameters

The 3300 XL 11 mm Proximity Probe operates across a wide temperature range. Specifically, its operating and storage temperature spans from -51°C to +177°C (-60°F to +351°F). However, note that exposure to temperatures below -34°C (30°F) may compromise the pressure seal. This seal uses a Viton O-ring to prevent process media from entering the probe. The recommended torque for the probe case is 15.2 N•m (133 in•lb). The maximum rated torque is 45.2 N•m (400 in•lb). The connector should be tightened finger tight, with a maximum torque of 0.565 N•m (5 in•lb). Additionally, the cable has a minimum bend radius of 25.4 mm (1.0 inch).

Installation Guide

Proper installation of the Bently Nevada 330701-00-30-90-02-00 is essential for optimal performance. First, verify that the mounting hole has a 1/2-20 UNF thread and is free from debris. Next, carefully inspect the probe tip for any physical damage. Then, thread the probe into the mounting hole by hand to avoid cross-threading. After that, use a torque wrench to tighten it to the recommended 15.2 N•m. Over-torquing can damage the delicate internal components. Subsequently, connect the probe to the extension cable using the ClickLoc connector. Ensure this connection is finger tight. Finally, power up the system and set the proper air gap according to your application's requirements. Always follow your site's safety procedures.
