{"title":"Platinum RTD Sensor - PT100 - 3 Wire 1 meter long","handle":"platinum-rtd-sensor-pt100-3-wire-1-meter-long","url":"/products/platinum-rtd-sensor-pt100-3-wire-1-meter-long","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.\n\nThis 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.\n\nKey Features\n\n\nPlatinum Element – 100 Ω at 0°C with a temperature coefficient of 0.385 Ω/°C\n\nHigh Accuracy – More precise and repeatable than thermocouples or thermistors\n\nStainless Steel Probe – Rated up to 550°C\n\n3-Wire Configuration – Third wire enables lead resistance compensation for accurate readings\n\n1 m Lead Length – Flexible placement away from the measurement point\n\n\n\nTip: 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.\n\n\nSpecifications\n\n\nSensor Type – PT100 (platinum RTD)\n\nResistance at 0°C – 100 Ω\n\nTemperature Coefficient – 0.385 Ω/°C\n\nMax Temperature – 550°C\n\nWiring – 3-wire\n\nLead Length – 1 m\n\nProbe Material – Stainless steel\n\n\nIdeal For\n\nPrecision temperature measurement in lab and industrial settings\nHigh-temperature monitoring (up to 550°C)\nArduino and Raspberry Pi projects with an RTD amplifier breakout\nFood processing, HVAC, and environmental monitoring\n\n\nPackage Contents\n\n1× PT100 Platinum RTD Sensor (3-wire, 1 m lead)\n","vendor":"Adafruit","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":12565,"title":"Default Title","sku":"AF-3290","price":25.84,"on_sale":false,"in_stock":true,"available_quantity":101,"option1":"Default Title"}]}
