Resistance temperature detectors (RTDs) are temperature sensors that contain a resistor that changes resistance value as its temperature changes, basically a kind of thermistor. In this sensor, the resistor is actually a small strip of Platinum with a resistance of 100 ohms at 0°C, thus the name PT100. Compared to most NTC\/PTC thermistors, the PT type of RTD is much most stable and precise (but also more expensive) PT100's have been used for many years to measure temperature in laboratory and industrial processes, and have developed a reputation for accuracy (better than \u003ca href=\"https:\/\/www.makerlab-electronics.com\/product\/thermocouple-amplifier-max31855\/\"\u003ethermocouples\u003c\/a\u003e), repeatability, and stability.\u003c\/p\u003e\n\u003cp\u003eThis high-temperature PT100 sensor is equipped with an stainless steel shield is good for up to 550°C.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003ePT100 features:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eBased on resistance measurement principles\u003c\/li\u003e\n\u003cli\u003eResistor material is Platinum with a value of 100 ohm at temperature 0°C\u003c\/li\u003e\n\u003cli\u003ePlatinum has a positive resistance temperature factor; resistance increases with rising temperature\u003c\/li\u003e\n\u003cli\u003eResistance variation is a function of temperature: 0.385?\/°C nominal\u003c\/li\u003e\n\u003cli\u003eHigh accuracy and stability compared to thermocouples, silicon-based temperature sensors, or thermistors\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eEach sensor comes with \u003cem\u003ethree wires. \u003c\/em\u003eTwo of the wires connect to either side of the platinum resistor like you'd expect. The \u003cem\u003ethird wire\u003c\/em\u003e is also connected to one end of the PT100. If your RTD amplifier supports 3-wire sensors, it will drive the resistor with the first two wires, and measure the voltage differences so that it can subtract any voltage drop from the wires. If your RTD amplifier only has 2-wire support simply leave the third wire disconnected.\u003c\/p\u003e\n\u003cp\u003e\u003ca href=\"https:\/\/www.makerlab-electronics.com\/product\/adafruit-pt100-rtd-temperature-sensor-amplifier-max31865\/\"\u003eUse our Adafruit RTD sensor breakout to connect this fine sensor to your favorite microcontroller\u003c\/a\u003e\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eTechnical Details:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e    Stainless steel tube: 4mm diameter by ~30mm long (size of stainless steel capsule may vary!)\u003c\/li\u003e\n\u003cli\u003e    Cable is approx 1m \/ 100cm long\u003c\/li\u003e\n\u003cli\u003e    Contains a PT100 temperature sensor\u003c\/li\u003e\n\u003cli\u003e    Three wires with terminal prong ends\u003c\/li\u003e\n\u003cli\u003e    Usable temperature range: -200 to 550°C (-328°F to +1,022°F)\u003c\/li\u003e\n\u003cli\u003e    Uses 3-wire interface\u003c\/li\u003e\n\u003cli\u003e    ±0.5°C Accuracy from -10°C to +85°C\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cdiv class=\"fluid-width-video-wrapper\"\u003e\u003c\/div\u003e\n\u003cdiv id=\"s3gt_translate_tooltip\" class=\"s3gt_translate_tooltip\"\u003e\u003c\/div\u003e","brand":"Adafruit","offers":[{"title":"Default Title","offer_id":42290970624191,"sku":"MLE00563","price":949.0,"currency_code":"PHP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0531\/3419\/6927\/files\/sg-11134201-7rd56-lvef4csqw9550e.jpg?v=1735816198","url":"https:\/\/makerlab.ph\/products\/platinum-rtd-temperature-sensor-pt100-3-wire-1-meter","provider":"Makerlab PH","version":"1.0","type":"link"}
