It features a 3-wire shielded design that maintains signal integrity and compensates for lead resistance, ensuring accurate temperature readings. The cable is built with silver-plated copper conductors and PTFE insulation for durability in industrial environments.\u003c\/p\u003e\u003ch2\u003eKey Specifications\u003c\/h2\u003e\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\u003eCable Length\u003c\/td\u003e\n\u003ctd\u003e1 meter\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWire Configuration\u003c\/td\u003e\n\u003ctd\u003e3-wire (PT100 standard)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eConductor Material\u003c\/td\u003e\n\u003ctd\u003eSilver-plated copper\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInsulation\u003c\/td\u003e\n\u003ctd\u003ePTFE (Teflon)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eShielding\u003c\/td\u003e\n\u003ctd\u003eAluminum foil with drain wire\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTemperature Range\u003c\/td\u003e\n\u003ctd\u003e-50°C to 200°C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\u003ch2\u003eWhat You Can Build With This\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003ePrecision temperature monitoring system for server rooms or labs\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"\/products\/esp8266-d1-mini-data-logging-project-kit\"\u003eData logging setup for environmental testing chambers\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003eIndustrial process control panel with remote PT100 probes\u003c\/li\u003e\n\u003cli\u003eDIY incubator or greenhouse temperature regulation project\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eCompatibility\u003c\/h2\u003e\u003cp\u003eThis cable works with any standard PT100 RTD sensor using a 3-wire connection, commonly found in industrial probes and thermowells. It pairs directly with temperature transmitters like the MAX31865 (commonly used with Arduino and Raspberry Pi) and with PLC analog input modules. The cable's resistance matches PT100 class A or B sensors, and the 3-wire configuration cancels lead resistance errors.\u003c\/p\u003e\u003ch2\u003eWiring Notes\u003c\/h2\u003e\u003cp\u003eThe cable's color code follows the typical PT100 standard: two wires of the same color (often red) connect to the excitation positive, while the third wire (white) connects to the negative input. For best accuracy, keep the cable away from high-voltage AC lines and ensure the shield drain wire is grounded at one end only.\u003c\/p\u003e\u003ch2\u003eWhy Buy from Compoden\u003c\/h2\u003e\u003cp\u003eEvery component is sourced from verified suppliers and tested for compatibility before listing.

The module handles the analog reading and communicates with Arduino via SPI.\u003c\/p\u003e\u003c\/details\u003e\u003cdetails\u003e\u003csummary\u003eWhat is the difference between a PT100 and a thermocouple?\u003c\/summary\u003e\u003cp\u003eA PT100 is a resistance temperature detector (RTD) that uses platinum's resistance change with temperature, offering higher accuracy and stability than thermocouples, which generate a voltage from two dissimilar metals.\u003c\/p\u003e\u003c\/details\u003e\u003cdetails\u003e\u003csummary\u003eCan I extend the cable to 5 meters?\u003c\/summary\u003e\u003cp\u003eYes, but for lengths over 2 meters, use the same 3-wire shielded cable to maintain accuracy. The 3-wire configuration minimizes lead resistance errors, but excessive length may require a transmitter near the sensor.\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.
