Platinum based resistor PT1000 Resistance Temperature Detector (RTD) uses a platinum resistor. Platinum has high and stable resistance for a metal, and a low temperature coefficient. Platinum based resistors make it easy to measure even the smallest changes in temperature with precision. Platinum also carries as advantages it does not react with most contaminant gases in the air and has very regular properties every batch. For these reasons it has become the standard for temperature sensing precision. Perfect for all PT1000-compatible 3D printers and especially for high temperature applications. PT1000 Compatibility RTDs work by using the basic principle that as the temperature of a metal increases, so does its resistance to the flow of electricity. An electrical current is sent through the sensor that is placed inside a cartridge inside a hot block. The resistance element within the cartridge is used to measure the resistance of the current being passed through it. Using lower currents will generate lower resistances especially at low temperature, that are harder to read. This leads to non-high-amperage mainboards, although compatible with the PT1000, will show low accuracy at low temperatures. Showing 50°C at room temperature is a possible reflection of this handicap.
