It provides precise temperature measurement from -50°C to 400°C, making it suitable for industrial process control, scientific experiments, and DIY automation. The 3-wire configuration ensures accurate readings by compensating for lead resistance, and the standard terminal block simplifies wiring.\u003c\/p\u003e\n\n\u003ch2\u003eKey Specifications\u003c\/h2\u003e\n\u003ctable\u003e\n  \u003cthead\u003e\u003ctr\u003e\n\u003cth\u003eSpecification\u003c\/th\u003e\n\u003cth\u003eValue\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n  \u003ctbody\u003e\n    \u003ctr\u003e\n\u003ctd\u003eSensor Type\u003c\/td\u003e\n\u003ctd\u003ePT100 RTD\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eProbe Length\u003c\/td\u003e\n\u003ctd\u003e10 inches (254 mm)\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eProbe Diameter\u003c\/td\u003e\n\u003ctd\u003e6 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eTemperature Range\u003c\/td\u003e\n\u003ctd\u003e-50°C to 400°C\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eAccuracy\u003c\/td\u003e\n\u003ctd\u003e±0.3°C at 0°C (Class B)\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eConnection\u003c\/td\u003e\n\u003ctd\u003e3-wire terminal block in head\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eMaterial\u003c\/td\u003e\n\u003ctd\u003e316 stainless steel probe\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eMounting Thread\u003c\/td\u003e\n\u003ctd\u003eM8x1.25\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003c\/tbody\u003e\n\u003c\/table\u003e\n\n\u003ch2\u003eWhat You Can Build With This\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003e\u003ca href=\"\/products\/esp8266-d1-mini-data-logging-project-kit\"\u003eIndustrial temperature monitoring and data logging system\u003c\/a\u003e\u003c\/li\u003e\n  \u003cli\u003eDIY PID controller for ovens, kilns, or soldering stations\u003c\/li\u003e\n  \u003cli\u003ePrecision 3D printer hotend temperature sensing\u003c\/li\u003e\n  \u003cli\u003e\u003ca href=\"\/products\/arduino-weather-logger-kit-for-hiking-trails-log-and-plot-data\"\u003eAmbient temperature logger for weather stations\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eCompatibility\u003c\/h2\u003e\n\u003cp\u003eThis sensor works with any RTD input module, such as the MAX31865 amplifier, which is widely available for Arduino, ESP32, and Raspberry Pi. It also connects directly to industrial PID controllers and PLCs. The recommended excitation current is 1 mA maximum to avoid self-heating, and supply voltage depends on the amplifier used (typically 3.3V or 5V). Pair with a MAX31865 for digital output via SPI, or with an analog front-end for direct ADC reading.\u003c\/p\u003e\n\n\u003ch2\u003eWiring Notes\u003c\/h2\u003e\n\u003cp\u003eInside the connection head, three terminals are provided: two carry the PT100 element signal, and the third is a compensation lead for 3-wire measurement. Connect all three to your RTD amplifier or instrument, matching the wiring diagram carefully. Keep lead wire runs as short as possible, and use shielded cable in electrically noisy environments. Always tighten terminal screws securely to prevent intermittent readings.\u003c\/p\u003e\n\n\u003ch2\u003eWhy Buy from Compoden\u003c\/h2\u003e\n\u003cp\u003eEvery component is sourced from verified suppliers and tested for compatibility before listing.

This sensor uses a platinum resistance element, whereas thermocouples generate a voltage, so wiring and interfacing differ.\u003c\/p\u003e\u003c\/details\u003e\n\u003cdiv class=\"compoden-handoff\" style=\"margin-top:24px;padding:16px;background:#f0f4ff;border-left:4px solid #2B4D8F;border-radius:4px;\"\u003e\n  \u003cp style=\"margin:0 0 6px 0;font-weight:600;color:#1A3560;\"\u003e📦 Free Setup Handoff Document Included\u003c\/p\u003e\n  \u003cp style=\"margin:0;font-size:0.95em;color:#333;\"\u003eEvery Compoden order includes a free setup handoff document — step-by-step instructions to get your component working within minutes.
