Bently Nevada 330130-085-00-00 is a high-performance extension cable designed for the 3300XL eddy current sensor system and is widely used in vibration,displacement and speed monitoring of industrial rotating machinery.The following is a comprehensive analysis of its core functions and technical parameters:
I.Product Overview
This cable belongs to the Bently Nevada 3300XL series and is used to connect the eddy current sensor probe and the preamplifier to form a complete non-contact measurement system.Its design supports high-precision and high-stability measurements and is suitable for harsh industrial environments.
II.Technical Parameters
Cable Length and Compatibility
-Standard length of 8.5 meters,which can be matched with 3300XL 8mm probes and 330180-50-00/CN/05 preamplifiers and other devices.
-Compatible with monitoring modules such as 3500/42,supporting signal transmission such as vibration,axial displacement,key phase,etc.
Electrical Performance
-Linear range:2mm or 4mm(depending on the probe model).
-Sensitivity:7.87V/mm(200mV/mil)or 3.94V/mm(100mV/mil).
-Frequency response:0-10kHz,maximum field wiring length up to 305 meters.
Environmental adaptability
-Operating temperature:standard type-52°C to+177°C,high temperature type up to+260°C.

-High temperature environment:With ETR(extended temperature range)probe,it supports stable operation under high temperature conditions.
IV.Installation and selection points
System matching
-The length of the extension cable and the length of the probe must be equal to the total length of the preamplifier(such as 5m or 9m system).
-It must be used with the same type of probe and preamplifier to ensure interchangeability and accuracy.
Environmental requirements
-High temperature scene:Choose high temperature cable and probe to avoid performance degradation caused by temperature.
-Corrosion protection:Use gold-plated copper connectors and protective sleeves to prevent loose connectors and external interference.
Calibration and maintenance
-Use TK-3E calibrator to regularly calibrate sensor linearity to ensure measurement accuracy.
-Follow industrial cable installation specifications(such as bending radius,laying spacing)to avoid mechanical damage.
