Description
PT100 Amplifier Board
Make your hotend run at higher temperatures, with better accuracy, and easier assembly with a PT100 sensor using this amplifier board. If you want experiment with printing the crazy high temperature materials, get more accurate temperature readings, and have a much more robust temperature sensor then a PT100 is an ideal option.
This amplifier will allow a sensing range of up-to and beyond 400C, the maximum safe working temperature of an all metal hotend.
This board allows you to connect our PT100 temperature sensor to any analog input pin of a 3D printer controller board. It amplifies the signal from the PT100 to a voltage level that your printer controller can read easily and accurately. This board is derived from the circuit design from the Ultimainboard V2 controller board, but with enhanced filtering for robust and accurate temperature measurement. Because of this you can simply select temperature sensor ’20’ in the marlin firmware to get correct calibration values.
