In addition to reading the posistion of encoders, it may be necessary to know the temperature of a specific part of the machine. In measurement machines, temperature detection allows for compensating the thermal expansion of the metallic parts making up the machine itself. The temperature value, through the formulas of the mathematical model, lets the machine take accurate measurements even in non-optimal enviromental conditions. The temperature-reading board can be connected to the encoder boards. It is of compact design and can share the same power supply and data transmission bus of the rest of the system. For maximum ease of installation, the temperature is read directly on the metal sheet used to fix the board, so no additional probe or sensor is required.
