Bently Nevada 330104-00-20-10-02-00 3300 XL 8 mm Proximity Probe

Product Overview

When unplanned downtime threatens production targets, the Bently Nevada 330104-00-20-10-02-00 3300 XL 8 mm proximity probe delivers precise shaft vibration and position measurements. This probe is designed for harsh industrial environments, featuring a rugged AISI 303 or 304 stainless steel case and a polyphenylene sulfide (PPS) tip. With a 1.0 meter (3.3 feet) total length and a miniature coaxial ClickLoc connector, it integrates seamlessly into existing monitoring systems. The 330104-00-20-10-02-00 is part of the trusted 3300 XL series, known for reliability in critical rotating machinery applications.

Technical Specifications

The 330104-00-20-10-02-00 operates with a nominal probe DC resistance of 7.59 ± 0.50 ohms from center conductor to outer conductor. It requires a power supply between -17.5 Vdc and -26 Vdc, with a maximum consumption of 12 mA. The output resistance is 50 Ω, and sensitivity is less than 2 mV change per volt change in input voltage. The probe tip material is polyphenylene sulfide (PPS), and the case material is AISI 303 or 304 stainless steel. These specifications ensure accurate and stable performance in vibration monitoring applications.

Industry Applications

This proximity probe is ideal for monitoring radial vibration and axial position in turbines, compressors, pumps, and motors. In a refinery, for example, the 330104-00-20-10-02-00 provides early warning of bearing wear or shaft misalignment, helping maintenance teams schedule repairs before catastrophic failure occurs. Its robust construction withstands oil, moisture, and temperature variations common in industrial settings.

Installation & Setup Guidance

For optimal performance, mount the probe with the specified gap of 1.27 mm (50 mils) to an AISI 4140 steel target. Ensure the unthreaded length is 00 mm and overall case length is 20 mm as configured. The M10 x 1 thread allows secure installation into standard mounting holes. Use the miniature coaxial ClickLoc connector for quick and reliable cable attachment. Verify the power supply meets the -17.5 Vdc to -26 Vdc requirement to maintain linear range.

Maintenance & Reliability

Regular inspection of the probe tip and cable for physical damage is recommended. The Viton O-ring seal maintains differential pressure between tip and case, so avoid exposing the probe to excessive pressure beyond its design limits. The stainless steel case resists corrosion, but periodic cleaning with a soft cloth and mild solvent helps maintain performance. The 330104-00-20-10-02-00 is designed for long service life with minimal maintenance, reducing total cost of ownership.

Compatibility & Integration

This probe is compatible with Bently Nevada 3300 XL 8 mm Proximitor sensors and extension cables. It works with standard monitoring systems that accept 3300-series inputs. The miniature coaxial ClickLoc connector ensures a secure connection without special tools. For system accuracy, always use 3300 XL 8 mm components together and calibrate to an AISI 4140 steel target.

Buying Guide & Purchasing Advice

Before purchasing, verify the total length option (10 = 1.0 meter) and connector type (02 = miniature coaxial ClickLoc) match your application. The agency approval option is 00 (not required).
