Measuring temperature in various systems can be quite challenging, such as in power breakers, railway power lines contacts or in electric traction substations. This article presents an on-line monitoring system with Human Machine Interface to supervise the temperature of a high railway voltage separator. The temperature is measured using an infrared temperature sensor that converts the temperature in an electrical signal, which, afterwards, is used as an analogue input for the Siemens S7-1200 PLC.
