Product Overview

The Bently Nevada 330730-040-01-05 is a high-performance 4.0-meter extension cable engineered specifically for the 3300 XL 11mm Proximity Transducer System. This specialized interconnect serves as the critical signal bridge between an 11mm proximity probe and a Proximitor sensor, facilitating the transmission of eddy-current data over a total system length of 5.0 meters. Designed for machinery monitoring environments where a standard 8mm probe lacks the necessary linear range, this cable supports a system scale factor of 3.94 V/mm (100 mV/mil). Its primary role is to ensure the high-fidelity delivery of non-contacting displacement and vibration signals, enabling the monitoring of larger gaps with the precision required for heavy-duty industrial rotating assets.

Strategic Industrial Deployment

This 11mm extension cable is indispensable for applications requiring an extended measurement window that exceeds the capabilities of standard proximity sensors. It is frequently deployed on large-scale steam turbines and gas turbines for monitoring axial (thrust) position and ramp differential expansion, where thermal growth and rotor movement require a wider linear range. Additionally, the 330730-040-01-05 is a vital component for rod drop measurements on reciprocating compressors, providing clear data for wear analysis of rider bands. Its robust construction makes it suitable for the high-temperature and chemically aggressive environments of oil refineries and power plants, ensuring that 3500 series monitoring racks receive stable timing and vibration signals for automated machinery protection.
