The Bently Nevada 330703-000-060-10-02-CN is a 6.0-meter extension cable designed for the 3300 NSv Proximity Transducer System. It facilitates high-accuracy vibration monitoring in confined spaces, featuring ClickLoc connectors and a rugged FEP jacket capable of withstanding temperatures up to +177°C.
The Bently Nevada 330703-000-060-10-02-CN serves as the vital link between a 3300 NSv proximity probe and a 3300 NSv Proximitor Sensor. As a specialized extension cable, it maintains the precise electrical impedance required to transmit high-frequency eddy current signals without distortion. The 3300 NSv (Near Surface) system specifically addresses applications with small target sizes or confined installation spaces where standard 8mm probes cannot function effectively. By using this cable, operators ensure the integrity of vibration and position data for critical rotating assets.
Maintenance professionals deploy the 330703 extension cable primarily in centrifugal compressors, small pumps, and aero-derivative gas turbines. Because the NSv system excels at monitoring small shafts (diameters less than 50mm), this cable provides the necessary reach from the machine case to the monitoring rack. Furthermore, the ClickLoc connectors feature a “positive lock” mechanism that prevents disconnection due to industrial vibration. The FEP (Fluorinated Ethylene Propylene) outer jacket offers superior resistance to corrosive fluids, lubricating oils, and extreme thermal cycling.
System accuracy depends entirely on matching the total electrical length of the probe and extension cable to the Proximitor Sensor’s calibration (typically 5.0 or 7.0 meters). For the 330703-000-060-10-02-CN, engineers must verify that the combined length of the probe lead and this cable adheres to the 3300 NSv system requirements. Additionally, the use of connector protectors is highly recommended for any junction located inside a machine housing to prevent oil contamination from grounding the signal.
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
