Unlike a PT100, which requires a dedicated\n  amplifier board (MAX31865 or equivalent) to interface with your printer's control\n  board, the PT1000 connects \u003cstrong\u003edirectly to any standard thermistor input pin\n  using a 4.7kΩ pullup resistor\u003c\/strong\u003e — the same pullup already present on most\n  3D printer boards. No additional hardware. No amplifier. Drop-in replacement for\n  any NTC thermistor in a 3mm cartridge mount, with a temperature ceiling of\n  \u003cstrong\u003e500°C\u003c\/strong\u003e and significantly better accuracy than NTC thermistors\n  at high temperatures.\n\u003c\/p\u003e\n\n\u003cp\u003e\n  ⚠️ \u003cstrong\u003eRequires 4.7kΩ pullup at the thermistor input.\u003c\/strong\u003e Most standard\n  3D printer boards (Octopus, Spider, SKR series, Duet) have this pullup onboard\n  or via jumper.

But they have two\n  significant weaknesses: their \u003cstrong\u003eresistance-to-temperature curve is highly\n  non-linear\u003c\/strong\u003e, meaning firmware accuracy degrades at temperature extremes,\n  and most NTC thermistors are rated only to 280–300°C, with accuracy degrading\n  above 250°C. The PT1000 is a Platinum RTD — its resistance changes\n  \u003cstrong\u003elinearly and predictably\u003c\/strong\u003e with temperature, delivering accurate\n  readings from room temperature to \u003cstrong\u003e500°C\u003c\/strong\u003e without the curve\n  fitting issues that affect NTC sensors at high temps. For anyone printing PEEK,\n  PEI, high-temperature Nylons, or any material pushing past 300°C, the PT1000\n  is the sensor that gives you accurate, reliable temperature feedback where an\n  NTC thermistor's accuracy has already deteriorated.\n\u003c\/p\u003e\n\n\u003ch3\u003ePT1000 vs PT100 — Same Accuracy, No Amplifier Board Required\u003c\/h3\u003e\n\u003cp\u003e\n  PT100 RTDs offer the same linear accuracy as PT1000s, but their low base resistance\n  (~100Ω at 0°C) makes them susceptible to cable resistance errors and requires a\n  dedicated signal amplifier chip (MAX31865) to interface with standard\n  microcontrollers. The PT1000 solves this by operating at \u003cstrong\u003e1000Ω\n  base resistance\u003c\/strong\u003e — ten times higher — which makes cable resistance\n  effects negligible and allows direct connection to a standard 4.7kΩ thermistor\n  input. You get PT100-class accuracy without the amplifier board, without the\n  extra wiring, and without the firmware configuration complexity.\n\u003c\/p\u003e\n\n\u003ch3\u003eNo Fiberglass Sleeving — Silicone-Insulated Cable\u003c\/h3\u003e\n\u003cp\u003e\n  Standard E3D NTC thermistors use fiberglass sleeving on the lead wires — functional,\n  but stiff and prone to fraying over time with repeated toolhead movement. The PT1000\n  uses \u003cstrong\u003esilicone-insulated leads\u003c\/strong\u003e that remain flexible at operating\n  temperatures and hold up better to the continuous flex of a moving toolhead.\n  The 50mm lead terminates in a \u003cstrong\u003eMolex Microfit 3.0 connector\u003c\/strong\u003e,\n  matching the standard E3D wiring ecosystem, with an extension cable included\n  to reach your controller without additional splicing.\n\u003c\/p\u003e\n\n\u003ch3\u003eKlipper Configuration\u003c\/h3\u003e\n\u003cp\u003e\n  Add the following to your \u003ccode\u003e[extruder]\u003c\/code\u003e section in\n  \u003ccode\u003eprinter.cfg\u003c\/code\u003e:\n\u003c\/p\u003e\n\n\u003cpre\u003e\nsensor_type: PT1000\nsensor_pin: # your thermistor pin\npullup_resistor: 4700\n\u003c\/pre\u003e\n\n\u003cp\u003e\n  For boards with a 2.2kΩ pullup (some BTT boards jumpered for PT1000):\n  consult your board's documentation and adjust \u003ccode\u003epullup_resistor\u003c\/code\u003e\n  accordingly, or use the standard 4.7kΩ input without the PT1000 jumper.\n\u003c\/p\u003e\n\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003ctable\u003e\n  \u003ctbody\u003e\n    \u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eBrand\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eE3D\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eSensor type\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003ePT1000 RTD (Resistance Temperature Detector)\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eBase resistance\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e1000Ω at 0°C\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eMax temperature\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e500°C\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eCartridge diameter\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e3mm\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eCartridge length\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e15mm\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eCable length\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e50mm\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eCable color\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eBlack\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eCable insulation\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eSilicone (no fiberglass sleeving)\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eConnector\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eMolex Microfit 3.0\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eRequired pullup\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e4.7kΩ (standard thermistor input)\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eAmplifier board required\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eNo — direct thermistor input connection\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eKlipper sensor_type\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003ccode\u003ePT1000\u003c\/code\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eCompatible heatblocks\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eE3D V6, Volcano, SuperVolcano, and all 3mm cartridge thermistor mounts\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003c\/tbody\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eWhat's Included\u003c\/h3\u003e\n\u003ctable\u003e\n  \u003ctbody\u003e\n    \u003ctr\u003e\n\u003ctd\u003e✅\u003c\/td\u003e\n\u003ctd\u003e1× PT1000 thermistor cartridge (3×15mm, Molex Microfit 3.0)\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003e✅\u003c\/td\u003e\n\u003ctd\u003e1× Extension cable\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003c\/tbody\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eWhen Do You Need This?\u003c\/h3\u003e\n\u003cp\u003e\n  The PT1000 is the right choice when you're pushing past the reliable range of\n  a standard NTC thermistor — specifically when printing materials above 280°C,\n  when you want more accurate temperature readback for fine-tuned pressure advance\n  and input shaper calibration, or when you're building or upgrading a hotend\n  for engineering-grade materials. It's also the straightforward upgrade path\n  for anyone who wants PTD-class accuracy without the additional hardware that\n  a PT100 setup requires. If your current NTC thermistor is failing or you want\n  a more accurate, longer-lasting sensor for a high-performance build, this is\n  the direct replacement with meaningful benefits beyond what a generic NTC\n  replacement provides.\n\u003c\/p\u003e\n\n\u003cp\u003e\n  Browse our full thermistor and heating component selection at\n  \u003ca href=\"\/collections\/thermistors-heating\"\u003eThermistors \u0026amp; Heating\u003c\/a\u003e, or\n  explore all hotend upgrades at\n  \u003ca href=\"\/collections\/3d-printer-upgrades\"\u003e3D Printer Upgrades\u003c\/a\u003e.\n\u003c\/p\u003e","brand":"West3D 3D Printing Supplies","offers":[{"title":"Default Title","offer_id":52735670878502,"sku":"E3D1137","price":24.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1004\/1986\/2822\/files\/pt1000-thermistor-e3d-west3d-printing-e3d-298388.jpg?v=1773259449","url":"https:\/\/supplies3d.shop\/products\/pt1000-thermistor-e3d","provider":"SUPPLIES3D","version":"1.0","type":"link"}
