Temperature ( Measurement )
- RTD
- Manufacturer : Rosemount, Prosensor
Technical Bulletins:
A resistance to temperature detector (RTD) is composed of a metallic element whose change in resistance is a function of temperature. Common materials for this element are platinum, copper, and nickel. In operation a small excitation current is passed across the element and the voltage, which is proportional to resistance, is then measured and converted to units of temperature. Selection of a proper sheath material, and connection head allow RTD's to be operated over a temperature range of -200°C à 600°C.
