Energy efficiency is an established concept of achieving the same result with less energy consumption.
It is about the relationship between the impact achieved and the energy invested. We deal a lot with energy, efficiency, losses, conversions, heating, cooling, lighting, surplus energy, new technologies, switching off appliances, monitoring, scales, ratings and similar concepts. But rarely, in fact never, in discussions on energy efficiency, do we talk about temperature sensors. This is actually a very interesting fact, because we all subconsciously believe what the temperature display is telling us and do not question the accuracy of the sensor and whether it should be checked and perhaps replaced before it fails completely.
What we are overlooking here is that energy efficiency starts with the temperature sensor.
Energy efficiency and temperature go hand in hand. Virtually all production processes and plants have a temperature that must be regulated and/or controlled at some stage.
Temperature sensors used in industrial processes are made of natural metals such as platinum, rhodium, nickel, copper, chromium and other metals that have good thermal properties. If we look at where energy consumption and emissions are highest, we quickly see that heating, cooling, chemical or high temperature processes are the most common. These in particular have the greatest negative impact on the useful life of temperature sensors, either by binding compounds from the environment that change their properties, by degrading due to over- or under-temperature and negative environmental influences, or by simply ageing.
