The Bently Nevada 330103-01-09-50-02-00 is a 3300 XL 8mm proximity probe with a 5.0m armored cable and 0.9-inch case. It delivers API 670 compliant vibration and position sensing for critical machinery.
The Bently Nevada 330103-01-09-50-02-00 serves as a critical sensor for industrial asset protection. This 8mm proximity probe measures shaft vibration and axial position with extreme accuracy. It utilizes advanced eddy current technology to track movement without physical contact. Furthermore, the system adheres to strict API 670 standards for machinery monitoring. This compliance ensures high performance in demanding oil and gas environments. Consequently, operators can rely on this probe for consistent data in high-temperature zones.
This specific model features a robust mechanical design for versatile field installation. It utilizes a 3/8-24 UNF thread for secure attachment to machine housings. The “01” unthreaded length provides 0.1 inches of clearance for specific mounting depths. Additionally, the “09” case length equates to a 0.9-inch total housing reach. The sensor includes a 5.0-meter integrated cable for extended routing capabilities. Moreover, the “02” option features stainless steel armor to protect the internal coaxial lead. These physical traits ensure the sensor withstands abrasive industrial conditions.
The 3300 XL series provides essential data for predictive maintenance programs. This probe monitors large rotating assets such as steam turbines and centrifugal compressors. Furthermore, it integrates seamlessly with 3500 series machinery protection racks. The gold-plated ClickLoc connectors maintain a stable electrical signal despite high-frequency vibration. Because it offers a wide linear range, it captures both subtle and significant shaft movements. This reliability helps facilities avoid unplanned downtime and expensive equipment damage.
Reliable sensing requires materials that resist degradation in harsh process environments. The probe tip uses high-performance polyphenylene sulfide (PPS) to withstand corrosive lubricants. Additionally, the FluidLoc seal prevents moisture from penetrating the cable assembly. This feature is crucial for maintaining signal integrity in humid or oil-saturated areas. The stainless steel armor further shields the cable from physical impacts and chemical splashes. Therefore, this probe offers a long service life even in extreme operational settings.

The Bently Nevada 31000-16-10-15-030-03-02 is a specialized proximity probe housing designed to physically protect a proximity probe and its integral cable within harsh industrial environments. Its primary function is to provide a secure, environmentally sealed mounting point on rotating machinery for acquiring critical vibration and position data. The housing is constructed from 304 Stainless Steel, offering robust protection against physical impact and corrosion. This specific configuration, 31000-16-10-15-030-03-02, features a 3/4-14 NPT external mounting thread for direct installation into a machine case. Internally, it accommodates a Bently Nevada 3300 XL 8 mm or 3300 5 mm probe, which is positioned by a 1.0-inch stinger (probe sleeve). The housing facilitates the signal path from the probe tip to the Bently Nevada 3500 Monitoring System. The probe, connected via an extension cable to a Proximitor Sensor, generates a high-frequency RF signal. The resulting eddy current field is used to measure the distance to the observed conductive target. The Proximitor Sensor conditions this signal into a calibrated DC voltage proportional to the gap, which is then transmitted to a 3500/42M Proximitor/Seismic Monitor module for analysis, alarming, and machinery protection.

In Oil & Gas applications, the 31000-16-10-15-030-03-02 housing provides essential protection for transducers monitoring centrifugal and reciprocating compressors, pumps, and gearboxes. Its 304 Stainless Steel construction and Viton seals ensure long-term integrity in environments containing corrosive elements such as H2S and hydrocarbons, a critical requirement for meeting API 670 standards for machinery protection systems. In Power Generation, this housing is extensively used on steam and gas turbines, exciters, and boiler feed pumps. It maintains measurement accuracy and reliability under conditions of high temperature and vibration, which is fundamental for monitoring shaft radial vibration, axial thrust position, and differential expansion. The passive mechanical design results in a high Mean Time Between Failures (MTBF), contributing to overall plant availability. When properly installed, the housing assembly provides an environmental rating equivalent to NEMA 4X and IP65, preventing ingress of dust, moisture, and process contaminants that could otherwise compromise signal integrity
