## Description

A platinum resistance temperature detector (RTD) with a 100 Ω resistance at 0°C, offering superior accuracy and long-term stability compared to thermocouples and thermistors. PT100 sensors are widely used in laboratory and industrial temperature measurement where precision and repeatability matter. This sensor features a stainless steel shield rated for temperatures up to 550°C and a 1-metre lead length with a 3-wire configuration for improved measurement accuracy. Key Features Platinum Element – 100 Ω at 0°C with a temperature coefficient of 0.385 Ω/°C High Accuracy – More precise and repeatable than thermocouples or thermistors Stainless Steel Probe – Rated up to 550°C 3-Wire Configuration – Third wire enables lead resistance compensation for accurate readings 1 m Lead Length – Flexible placement away from the measurement point Tip: The 3-wire design allows compatible RTD amplifiers (such as the MAX31865) to compensate for lead wire resistance. If your amplifier only supports 2-wire connections, leave the third wire disconnected. Specifications Sensor Type – PT100 (platinum RTD) Resistance at 0°C – 100 Ω Temperature Coefficient – 0.385 Ω/°C Max Temperature – 550°C Wiring – 3-wire Lead Length – 1 m Probe Material – Stainless steel Ideal For Precision temperature measurement in lab and industrial settings High-temperature monitoring (up to 550°C) Arduino and Raspberry Pi projects with an RTD amplifier breakout Food processing, HVAC, and environmental monitoring Package Contents 1× PT100 Platinum RTD Sensor (3-wire, 1 m lead)

**Product Type:** physical
