Bently Nevada 330104-00-03-10-01-05 3300 XL Proximity Probe

Description

330104-00-03-10-01-05 specifies a Bently Nevada 3300 XL 8 mm proximity probe featuring an M10 x 1 metric thread and protective stainless steel armor over the 1.0-meter cable. This specific configuration is defined by a 0 mm unthreaded length, a 30 mm overall case length, a miniature ClickLoc coaxial connector with a connector protector, and CSA, ATEX, and IECEx hazardous area approvals. Unlike configurations with non-armored designs or standard unthreaded lengths, this variant is shielded for harsh mechanical environments and threaded up to the tip.

The probe works on the eddy-current principle, supplying critical position and vibration signals to a companion 3300 XL Proximitor Sensor. It provides non-contact measurements of shaft vibration and axial position on rotating machinery. The integral coaxial armor prevents cable damage from abrasion, pinching, or flying debris, which is essential in demanding industrial turbomachinery environments.

Features

• M10 x 1 metric threads with a 30 mm case length and 0 mm unthreaded section (fully threaded case).
• Stainless steel cable armor shielding the 1.0-meter coaxial cable against mechanical wear and abrasion.
• Miniature ClickLoc coaxial connector equipped with a factory connector protector to prevent ingress of moisture and oil.
• Hazardous area approvals (CSA, ATEX, IECEx) included under the Option 05 designation.
• Thick polyphenylene sulfide (PPS) tip molding for chemical resistance and mechanical ruggedness.

Applications

Typical applications include vibration and position monitoring in industrial rotating machinery, specifically:

• Steam turbines and gas turbines
• Centrifugal compressors and axial compressors
• Heavy-duty industrial pumps and gearboxes
• Hydroelectric generators and electric motors
• Shaft radial vibration, axial position, and speed sensing

Installation Guidelines

Install the probe by threading it into the mounting bracket or machine housing. Since this probe is fully threaded (0 mm unthreaded length), ensure the thread engagement matches the machine casing and does not exceed 15 mm to avoid binding during installation. Tighten the probe case to the recommended torque of 11.2 N-m (100 in-lb). Maintain minimum side-view clearance of 40 mm around the probe tip to prevent crosstalk or false readings from surrounding metal surfaces. Connect to a standard 3300 XL 9-meter extension cable (or adjust for overall system length) and use the included connector protector to prevent fluid contamination of the coaxial coupling.

Compliance and Certifications

The 330104-00-03-10-01-05 proximity probe complies with major global hazardous area standards, designated by option 05:
