Vibration monitoring module

21 February 2023

With the new VSE9xx diagnostic modules from ifm electronic, vibration monitoring and analysis can be carried out directly in the field, eliminating the need to route signals from accelerometers back to the control panel.

The compact modules feature robust construction and an IP67 protection rating, allowing them to be mounted in almost any field location without additional protection. They use standard M12 connectors to facilitate speedy installation and retrofitting, and they are compatible with all commonly used acceleration sensors.

Modules in the VSE9xx range accept inputs from up to four acceleration sensors, and also have two auxiliary inputs – one pulse, one analogue – which can be used to collect additional information related to condition monitoring, such as speed and temperature. 

They can accept accelerometer inputs covering the frequency range of 0 to 12 kHz, with a sampling rate of 100 kHz. The modules evaluate the signals from the sensors in real time and will provide local alarm outputs. Additionally, they will provide full spectrum process data for further analysis by ifm electronic’s proprietary evaluation software or a third-party analytics package.

Ideally suited for adding vibration monitoring to existing equipment, as well as for use in new equipment designs, VSE9xx modules are available in four versions which differ only in their networking compatibility. The VSE903 is for use with TCP/IP systems, the VSE950 with PROFINET, the VSE951 with Ethernet/IP and the VSE953 with Modbus/TCP. All types provide robust separation between the automation and IT networks.
