Platinum RTD Temperature Probes

“Resistance thermometers, also called resistance temperature detectors or resistive thermal devices (RTDs), are temperature sensors that exploit the predictable change in electrical resistance of some materials with changing temperature. As they are almost invariably made of platinum, they are often called platinum resistance thermometers (PRTs). They are slowly replacing the use of thermocouples in many industrial applications below 600 °C, due to higher accuracy and repeatability.”- wikipedia.org

QTI allows design engineers a wide degree of flexibility when designing RTD’s for their specific applications. From custom housings to a wide selection of wire and cable options, QTI’s Application Engineers are here to help. Click here to chat live with an application engineer.
