Bentley 18745-04 is a preamplifier module in the Bentley Nevada TSI(Turbine Supervisory Instrumentation)system,mainly used for vibration,displacement,and condition monitoring of industrial equipment.The following is a comprehensive analysis of its core functions and technical features:
1、Core functions and design
Vibration and displacement monitoring
As the core component of the eddy current sensor system,it can collect real-time parameters such as vibration,axial displacement,key phase,etc.of rotating machinery(such as steam turbines,compressors,motors)by connecting probes and extension cables,supporting high-precision dynamic monitoring.
Support 3300XL 8mm probe system,compatible with 4-meter non armored or armored extension cables(such as 330130-040-00-00),ensuring stable signal transmission and anti-interference ability.
Industrial grade protection and compatibility
Compatible with multiple preamplifier models(such as 330180-50-00/CN,330180-51-00/CN),supports corrosion-resistant ClickLoc gold-plated copper connectors,easy to install and tool free,suitable for complex industrial environments such as high temperature and humidity.
The protection level is not clearly indicated,but based on TSI system design standards,it is speculated to have anti vibration,dustproof(IP65/IP67),and wide temperature range adaptability(-20°C to 60°C).
System Integration and Expansion
It can be integrated into the 3500 series monitoring system,supporting multi-channel data acquisition and analysis,and is suitable for monitoring the status of large rotating equipment in industries such as power plants,steel,and petrochemicals.
Support analog output modules(such as ROM-121 series)and network communication interfaces(such as SY/MAX)to achieve remote data transmission and centralized monitoring.
