RTD PT00 Temperature Sensor Products

Description

A Resistance Temperature Detector (RTDResistance Temperature Detector), also known as a resistive temperature device, has a metal film or filament as its sensing element with a resistance that increases with temperature. An RTD is used when high precision and stability is needed.

RTD's that are labeled PT100 are referring to the resistance of 100 Ohms at 0°C of a small strip of Platinum (Pt). RTD PT100 probes are commonly available in 3-wire or 4-wire configurations. If only two wires are used, the leads will have an unknown resistance that will be affected by temperature. The third wire enables temperature compensation by measuring the resistance of one of the leads (the resistance of the other lead can be inferred from the assumption that all the leads are identical in length and composition). In the four wire configuration, the resistance of both leads are measured.

RTDs require sensitive electronics and signal conditioning to read the small changes in resistance. The most common RTD amplifier ICIntegrated Circuit is the MAX31865 with a digital SPISerial Peripheral Interface output. Adafruit and generic modules are available for the MAX31865 IC to make it easier to interface to.

More details on how RTDs work, the different wire configurations of probes, and amplifier modules, can be found in the Temperature Sensors article.
