Bently 330180-90-05 is a preamplifier manufactured by Bently Nevada,mainly used for vibration monitoring.The following are the details of the product:
1.Product Overview
Model:330180-90-05
Manufacturer:Bently Nevada
Application:Vibration and displacement measurement of large and medium-sized rotating machinery,as well as key phase and speed measurement.It can be widely used in vibration monitoring of steam turbines,water turbines,fans,compressors,air separators,turbo expanders,motors and generators,exciters,gearboxes,water pumps,etc.It is suitable for power plants,chemical plants,refineries,steel plants,machinery plants,water pump plants,fan plants,university research units,and automation instrument complete sets of enterprises.
2.Technical Features
Receiving Signals:
Receive signals from non-contact 3300 series or 3300XL eddy current probes and extension cables.
Anti-interference ability:
Strong anti-interference ability,can be used directly in industrial production sites with strong interference.
Improved RFI/EMI immunity meets European electromagnetic compatibility standards,and no special shielded conduit or metal housing is required,reducing installation costs and complexity.
Installation method:
Panel mounting and DIN rail mounting options are available,which can flexibly adapt to different installation environments.
The mounting base provides electrical isolation without the need for a separate isolation plate.
System compatibility:
Compatible with Bentley’s vibration monitor products(such as 3500 modules,2300/20,1900/65,etc.),and the received signals can be transmitted to these products for further processing and analysis.
Self-diagnosis and display function:
With complete self-diagnosis and display functions,when a PLC or external input device and actuator fails,the cause of the fault can be easily identified and quickly eliminated based on the information provided by the LED on the PLC or the programmer.
Performance indicators:
The sensitivity is 7.87mV/μm(200mV/mil),with high measurement accuracy.
Simplified wiring terminals make installation and wiring work more convenient.
3.Product Specifications
Electrical length:The electrical length of the preamplifier probe plus the electrical length of the extension cable must be equal to the electrical length of the preamplifier to ensure the normal operation of the system.
Total length:The total length of the preamplifier is 5 meters(reference information,the specific length may vary depending on the product batch and model).
4.Power supply and output
Power supply:
Without safety barrier:-17.5Vdc to-26Vdc
With safety barrier:-23Vdc to-26Vdc
Maximum current:12mA
Output:voltage or current signal,with output short circuit protection function.
