1.Product positioning and core functions
1.1 Application scenarios
Steam turbine/generator monitoring:
In nuclear power plants and thermal power plants,real-time monitoring of rotor axial displacement and radial vibration can be performed to prevent faults such as friction between moving and static parts and rotor imbalance,and ensure safe operation of the unit.
Usually used in conjunction with the 3500 series monitoring system,data is transmitted to the DCS/PLC system through 4-20mA or Modbus signals to achieve alarm interlock control.
Compressor/fan monitoring:
In the fields of petrochemicals and natural gas transportation,compressor rotor vibration is monitored,and bearing wear and gear failure are diagnosed by combining spectrum analysis to optimize maintenance plans.
Support Bently Nevada’s System 1 software for vibration trend analysis and fault warning.
Turbine/pump monitoring:
In hydropower stations and municipal water supply systems,turbine main shaft vibration is measured to prevent faults such as cavitation and blade breakage,and extend equipment life.
1.2 Technical highlights
High-precision eddy current sensing technology:
Using the eddy current principle,non-contact measurement of the gap between the rotor and the probe,the resolution can reach 0.1μm,which is suitable for monitoring the tiny vibration of high-speed rotating machinery(speed>3000rpm).
Wide temperature adaptability:
The operating temperature range is-50℃to+175℃(probe head),which can withstand high/low temperature environments in industrial sites to ensure sensor stability.
Strong anti-interference ability:
Electromagnetic compatibility(EMC)complies with IEC 61000-4-2/3/4/5/6 standards,resists interference such as electrostatic discharge,electrical fast transients,surges,etc.,and ensures signal reliability.
Modular design:
Seamlessly compatible with Bently Nevada 3300/3500 series preamplifiers and extension cables,supports hot-swap replacement,and reduces downtime maintenance time.
