PT100's are high temperature, high accuracy temperature sensors that you can now use on your E3D V6 Ho tEnd instead of a thermistor or thermocouple. PT100's are able to measure higher temperatures than thermistors – upto 400°C, and are more accurate then both thermistors and thermocouples in general. Our PT100 sensors are also very easy to handle, being of a metal cartridge type construction that is secured with a set screw, no more fiberglass sleeving or clamping washer. The PT100 sensor will not fit in the standard E3D Hotends, but can be used with E3D V6, Chimera, Lite6, and Kraken by using the PT100 Heater Block available in the spares and extras section. Please be aware that a PT100 is not the same as a thermistor and unless your electronics explicitly supports RTD Sensing devices you will need an amplifier board. The Ultimaker 2 uses PT100 sensors by default, and this sensor allows you to connect your E3D Hotend and Ultimaker electronics with no alteration to the electronics or firmware of the Ultimaker 2.
