PT1000 platinum resistance thermometer is a type of temperature sensor commonly used for temperature measurement. Its operation is based on the temperature characteristics of platinum resistance, whereby the resistance value of the platinum resistance changes correspondingly with temperature variations. PT1000 refers to a platinum resistance with a resistance value of 1000 ohms at 0 degrees Celsius.
Thin film platinum resistance temperature detectors (Pt-RTD) consist of a thin film platinum deposited on a ceramic substrate.Thin film Pt-RTD’s provide cost advantages when compared to wire wound Pt-RTD’s because of their lower material cost factor.
