SKF Multilog On-line System DMx and Temperature Measurements

The SKF Multilog On-line System DMx was introduced as an intrinsically safe, vibration based Machine Protection System. However, there have been requests for the device to include temperature measurements.

This is a common requirement to upgrade obsolete analog API 670 monitoring systems. These would often measure (for example) 16 channels of vibration and axial position, and 6 channels of temperature. Each temperature sensor chain would involve direct connection of a Resistive Temperature Detector (RTD) or Thermocouple to the monitor.

This application note describes how to address this situation with an SKF Multilog DMx.
