Product Overview
Bently 330980-51-00 is the core component of the Bently Nevada 3300 XL series preloader and is a key device for industrial vibration and displacement monitoring systems.It is mainly used for real-time monitoring and protection of vibration,displacement,speed and other parameters of rotating machinery(such as steam turbines,compressors,generators,etc.),and is widely used in electric power,metallurgy,petrochemical,chemical and other fields.
Technical parameters
Basic parameters
Model:330980-51-00
Series:3300 XL NSv(unshielded eddy current sensor system)
Type:Proximitor Sensor
compatibility:
Adapt to 3300 XL series probes(such as 330901-330910)
Supports 5-meter or 7-meter extended cable(the total system length is determined by the sum of the probe and cable)
Installation method:Rail-type or panel-type installation,compatible with traditional 4-hole base.
Environmental adaptability
Operating temperature:-40°C to+85°C(standard)
Protection level:IP20(need to be installed in the control cabinet)
Anti-interference capability:Complies with the European Electromagnetic Compatibility Standard(EMC)and resists radio interference without additional shielding.
Electrical performance
Input/Output:
Input:Connect the eddy current probe(such as 330901-330910)
Output:4-20mA signal,compatible with Bently 3300 XL monitors(such as 990/991 transmitters),2300/20 or 1900/65 systems.
Power supply requirements:24 V DC.
Core functional features
High reliability design
Anti-interference capability:With SpringLoc terminals and gold-plated copper ClickLoc connectors,anti-loosen design and can be installed without special tools.
Temperature adaptability:Supports ETR(large temperature range)probes and cables,and can operate stably in high temperature environments such as 260°C.
Modularity and compatibility
System integration:It forms a complete monitoring chain with the Bently 3300 XL NSv sensor system(probe,extension cable,preloader),and supports multi-parameter measurements such as vibration,displacement,and speed.
Scalability:Can be mixed with 3300 Series 5mm/8mm probes,but performance depends on compatibility of non-XL series components.
Industrial-grade application optimization
Signal processing:Convert the weak eddy current signal of the probe into a standard 4-20mA signal and adapt to industrial control systems(such as DCS,PLC).
Self-diagnosis function:supports online status monitoring,triggering alarm or protection actions when abnormal.
Typical application scenarios
Electricity Industry
Steam turbine and generator bearing vibration monitoring to prevent shutdown caused by mechanical failure.
Petrochemical and metallurgy
Displacement and vibration monitoring of compressors and pump units ensures the stability of process equipment.
Machinery manufacturing
Speedand vibration protection of high-speed rotating machinery(such as fans,centrifuges).
Rail Transportation
Vehicle wheel-to-bearing vibration monitoring to ensure operational safety.
