PT100 RTD Sensor Extension Cable - 1 Meter | Compoden
PT100 RTD Temperature Sensor Extension Cable (1 Meter)
This 1-meter PT100 RTD extension cable connects your PT100 temperature sensor to a transmitter, controller, or data logger. 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.

Compatibility
This 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.
Wiring Notes
The 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.
Why Buy from Compoden
Every component is sourced from verified suppliers and tested for compatibility before listing. We've spent 10 years building projects for makers, schools, and institutions across India. Ships from Bengaluru in 3-5 days. If defective on arrival, replace within 7 days.
Is this compatible with Arduino?
Yes, when used with a MAX31865 RTD amplifier module, this 3-wire cable connects easily. The module handles the analog reading and communicates with Arduino via SPI.
What is the difference between a PT100 and a thermocouple?
A 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.
Can I extend the cable to 5 meters?
Yes, 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.
