English

Subject field(s)
  • Electrical Measuring Equipment
  • Electrical Component Manufacturing Equipment
DEF

A temperature sensing-device that changes resistance at a predetermined rate in response to changes in temperature.

CONT

RTDs or resistance temperature detectors work in a similar way to thermistors and measure ohmic resistance to measure temperature. They are connected to a circuit in a similar way to a thermistor but they have a much wider temperature range and can measure extreme temperatures.

OBS

The RTD's resistance vs. temperature characteristics are stable, reproducible, and have a near linear positive temperature coefficient from -200 to 800 °C.

French

Domaine(s)
  • Appareils de mesures (Électricité)
  • Matériel et équipement électriques
CONT

Le détecteur de température à résistance, ou RTD, est l'un des instruments les plus précis. [Il est constitué] de matériaux conducteurs de haute pureté tels que le cuivre, le platine, le nickel et [il est] enroulé en bobine ou recouvert d'un film mince.

Spanish

Campo(s) temático(s)
  • Equipo de medición eléctrica
  • Equipo de fabricación de componentes eléctricos
DEF

Sensor de temperatura que detecta la variación de la resistencia de un determinado conductor en función de la temperatura del ambiente.

OBS

RTD: por sus siglas en inglés (resistance temperature detector).
