Rox™ RTDs ■ Standard curve interchangeable ■ Good radiation resistance induced errors ■ Standard curve interchangeable ■ Good radiation resistance field-induced errors over other ruthenium oxides ■ Standard curve interchangeable ■ Good radiation resistance interchangeability from induced errors Ruthenium Oxide (Rox™) RTDs Ruthenium oxide temperature sensors are thick-film resistors used in applications involving magnetic fields. These composite sensors consist of bismuth ruthenate, ruthenium oxides, binders, and other compounds that allow them to obtain the necessary temperature and resistance characteristics. Each Lake Shore Rox™ model adheres to a single resistance versus temperature curve. temperature) is useful down to 50 mK and has better interchangeability than the RX-202A as well as low magnetic field- induced errors below 1 K. temperature) is useful down to 10 mK (calibrations available down to 20 mK) unique package design maximizes thermal connection and minimizes heat capacity magnetic fields. in magnetic field-induced errors over other commercially available ruthenium oxide temperature sensors with similar resistances and sensitivities. Most ruthenium oxide sensors have a maximum useful temperature limit well below room temperature, where the sensitivity changes from negative to positive. The RX-202A however, is designed to have a monotonic response from 0.05 K up to temperature) has a unique resistance and temperature response curve combined with low magnetic field- induced errors, and is the best choice for Typical Rox™ Resistance Values Typical Rox™ Sensitivity Values Typical Rox™ Dimensionless Sensitivity Values Lake Shore Cryotronics, Inc. e-mail: [email protected]
