BENTLY 1900/27 monitor provides mechanical protection

1900/27 External Termination Blocks

The three types of External Termination Blocks used with a Proximitor/Seismic I/O Module 1900/27 are the Proximitor/Seismic External Termination Blocks, the Bussed Proximitor/Seismic External Termination Blocks, and the Recorder External Termination Blocks. Each type comes with either Terminal Strip or Euro Style connectors.

The boards and components inside of 1900/27 modules cannot be repaired in the field. Maintaining a 3500 rack consists of testing module channels to verify that they are operating correctly. Modules 1900/27 that are not operating correctly should be replaced with a spare. This section shows how to verify the operation of channels in an Proximitor/Seismic Monitor (Section 5.1), how to adjust the scale factor (Section 5.2.1), and zero position (Section 5.2.2).

The Bently 3500 online vibration monitoring system from the United States is used for mechanical protection applications, for vibration monitoring of large and medium-sized rotating machinery such as steam turbines, compressors, fans, water pumps, coal mills, gearboxes, motors, etc. It is widely used in steel, power, metallurgy, petrochemical petroleum, natural gas, petrochemical, chemical and other related industrial fields. The highly modular design of the system includes:
