Suitable for industrial environments subject to high temperature,high pressure,strong vibration,and high electromagnetic interference(such as those in the power,oil and gas,chemical,and metallurgical industries).
Compatible with the Bently Nevada 3300/3500/4000 series monitoring systems and System 1 software,supporting predictive maintenance and fault diagnosis.II.System Composition and Core Components
The 149992-02 is typically a standardized kit containing the following key components(specific configuration is subject to order):
1.Proximity Probe
Example models:3300 XL 11mm or 3300 XL 25mm(selectable range).
Function:Non-contact measurement of the gap between the rotor and the probe tip,providing real-time information on equipment operating conditions(such as vibration,displacement,and differential expansion).
Key Features:
High Temperature Resistance:The standard probe supports temperatures from-35°C to+175°C,while the high-temperature model(HT)extends to-35°C to+260°C.
Vibration Resistance:The probe structure is reinforced to withstand high-vibration environments(vibration amplitude>500μm).
Explosion-Proof Certification:ATEX/IECEx Zone 0/1/2 certified,suitable for hazardous areas such as oil,gas,and chemical industries.
Material:The probe head is made of Inconel 600 alloy(highly corrosion-resistant),and the housing is 316L stainless steel.Protection Rating:IP68(dustproof and waterproof,withstands short-term immersion).
2.Extension Cable
Length:5m,9m,or 15m(standard,other lengths available).
Function:Connects the probe to the proximitor sensor,transmits high-frequency signals,and shields against electromagnetic interference(EMI/RFI).
Key Features:
