When measuring temperatures on electrical machines, the readings from the stator, bearings, and surfaces are very relevant. For example, they reflect anomalies in induction currents, lubricant pressure, or cooling. If the electrical machine is used as a drive for a pump, monitoring the temperatures of the pumped fluids can be an effective way to prevent the drive from becoming overloaded.
If fluids have a solidification point above the ambient temperature, monitoring of the temperature can be used to delay the start-up of the pump until the viscosity of the fluid reaches operating level. The transmitted signals are continuously monitored by the module for under- or overruns of selectable trip values. If the set values are reached, defined processes are triggered: In the most basic of instances, this is a shutdown of the affected component.
