The PCB2225 is a Pt-RTD temperature sensor mounted on a small PCB board, designed for precision and stability in calorimetry applications. Its board design simplifies connection and assembly in probe configurations. A unique "heat break" conductive path minimizes stem effect measurement error by reducing heat transfer from connection wires to the sensor. The sensor offers easy connection to cables via solderable pads and quick, economical temperature probe assembly with high accuracy and interchangeability. Available in large volumes.
