Bently Nevada 128718-01 Product Details
(High-performance eddy current displacement sensor system for rotating machinery monitoring in harsh industrial environments)
I.Product Overview
Model:128718-01
Brand:Bently Nevada(a subsidiary of Baker Hughes,a leading brand in industrial condition monitoring)
Type:Eddy current displacement sensor system(includes probe,extension cable,proximitor sensor,and may include mounting accessories)
Core Positioning:
Designed for extreme industrial environments such as high temperature,high pressure,high vibration,and severe corrosion.
Suitable for monitoring axial displacement,radial vibration,and shaft centerline trajectory of critical rotating equipment such as steam turbines,compressors,generators,and gas turbines.
Compatible with the Bently Nevada 3300/3500 monitoring systems,System 1 software,and third-party control systems(such as PLCs/DCSs).II.System Composition and Configuration
The 128718-01 is typically a complete kit,including the following core components(specific details are subject to order confirmation):
Proximity Probe
Example Model:3300 XL 11mm or 3300 XL 25mm(Long-Range Model).
Function:Non-contact measurement of the gap between the rotor and the probe tip,providing real-time information on the device’s operating status.
Key Features:
High-Temperature Resistance:The standard probe supports temperatures from-35°C to+175°C,while high-temperature models(such as the HT)extend to-35°C to+260°C.
Vibration Resistance:The probe’s reinforced structure withstands high-vibration environments(e.g.,vibration amplitudes>500μm).
Explosion-Proof Certification:ATEX/IECEx Zone 0/1/2 certified,suitable for hazardous areas such as the oil,gas,and chemical industries.
Extension Cable
Length:5m,9m,or 15m(standard configuration;other lengths available on request).Function:Connects the probe to the preamplifier,transmits high-frequency signals,and shields against electromagnetic interference(EMI/RFI).
Key Features:
Low loss:Signal attenuation<0.3dB/m(ensuring long-distance transmission accuracy).
Chemical resistance:The outer sheath is made of fluororubber(FKM)or polytetrafluoroethylene(PTFE),resistant to corrosion by oil,water,and chemical solvents.
