Response time

Less than 1 millisecond.

Compatibility

This module is compatible with other modules in the 3500 series and can be seamlessly integrated into existing systems.At the same time,it also supports field-upgradeable firmware and asset management data reporting.

Application and Function

The BENTLY 3500/25 149369-01 module is mainly used to provide keyphase signals for the monitor module in the 3500 frame.By receiving input signals from eddy current sensors or electromagnetic sensors and converting them into digital key phase signals,the module can accurately indicate when the key phase mark on the shaft passes the key phase probe.This is essential for measuring machine speed,monitoring machine axial vibration,and predicting the operating status of equipment.

In addition,the module is also widely used in industrial fields such as oil and gas,power,petrochemical,papermaking,and steel for monitoring and protecting key rotating equipment such as generators,turbines,pumps,and compressors.By monitoring vibration and other parameters in real time,timely detecting equipment abnormalities and taking corresponding maintenance measures,it helps to improve equipment reliability and efficiency,reduce downtime,and prevent accidents caused by mechanical failures.
