Model Segmentation Analysis
330930 – 065 – 02 – 00
330930: Basic model → 3300 XL NSv dedicated electromagnetic eddy current extension cable
065: Total cable length 6.5 meters
02: Unarmored FEP high-temperature resistant cable, with protective sheaths at both ends and resistant to bending damage
00: General CE standard, without ATEX/IECEx explosion-proof special certification
Core Electrical Parameters
Cable Type: 75Ω impedance coaxial shielded cable, FEP fluoropolymer high-temperature resistant insulation outer skin
Operating Temperature: -51℃ ～ +177℃, suitable for high-temperature unit operation conditions
Connector Specifications: Both ends are ClickLoc micro coaxial quick connectors, one end is connected to the NSv probe, and the other end is connected to 330980 preamplifier
System Sensitivity: The standard of the entire NSv system is 200mV/μm (7.87V/mm)
Total System Length to be Matched: The cable length of the probe itself + 6.5m extension cable = the total length for calibration of the preamplifier, the length must be strictly matched, otherwise measurement drift and false alarms will occur
IV. The Three Components of the Entire NSv Eddy Current Sensor (All Must Be Included)
NSv Probe: 330903, 330908 series small target side-view type eddy current probes (suitable for shaft diameters < 51mm, narrow installation positions)
This Extension Cable: 330930-065-02-00 (6.5m)
NSv Special Preamplifier: 330980 series (cannot be replaced by 330180 conventional preamplifier)
Application Scenarios
Radial vibration, axial displacement, and phase rotational speed monitoring of centrifugal air compressors, process compressors, and refrigeration compressors in narrow installation positions
Small-diameter shafts, narrow installation space units, where conventional 8mm/5mm probes cannot be installed
Matched with the 3500 series vibration monitoring framework of Ingersoll Rand to achieve unit interlock protection and fault warning
Key Selection Precautions
Only compatible with 3300 XL NSv exclusive system, cannot be combined with 330130, 330171, etc. conventional probe cables
00 = No sheath, unarmored; 01 = Stainless steel armored; 02 = Non-armored with connector protection; 03 = Armored with sheath
Common lengths of the same series: 4.0m, 4.5m, 6.0m, 6.5m. Inconsistent cable lengths will directly lead to measurement failure
