PT100 RTD 500°C Thermistor

The wonders of 3D printing just keep getting better. 3D Printers constantly evolve with new technology being added to the many moving parts of these awesome machines. With so many big components, it is sometimes hard to notice the smaller parts at play that increase your 3D printer’s capabilities ten-fold. The PT100 RTD Thermistor is one of these crucial pieces that make it possible to crank up your printing temperature to 500°C.

This PT100 RTD Thermistor from Slice Engineering is designed as a convenient spare part for almost any hotend or electronics that cater for the PT100. Do note, however, that the PT100 does require a MAX31865 amplifier in most cases which is not included here. The PT100 RTD Thermistor uses a platinum resistor which offers an impressive detection range of -50°C to 500°C. When installed into the heater block, the thermistor helps accurately detect the printing temperature for you to perform delicate changes and print at the exact temperatures you need for your unique 3D filaments.

Supplied with 2m long lead wires, the PT100 RTD Thermistor is a drop-in replacement for almost any 3D printer. The Biqu H2 500°C extruder and the Octupus Pro Controller Board both cater for the PT100 sensor for it’s high quality temperature detection that propels your 3D printing to the next level.

Please Note: This PT100 RTD Thermistor does not come with the MAX31865 amplifier, which is required for most applications. If you are looking for a high temperature thermistor without a required amplifier, then be sure to check out our PT1000 RTD Thermistor in stock.

Typical Applications for the PT100 RTD Thermistor:

These PT100 RTD Thermistors are primarily stocked as replacements for high temperature hotends such as the Biqu H2 500°C Direct Drive, but their utility allows Makers to use these thermistors for interesting applications. The Octopus Pro Controller Board provides built-in support for the PT100 for its superior temperature resistance and detection. If you are keen to experiment with the PT100 within other temperature sensitive DIY projects, please note a MAX31865 amplifier is required in most applications.
