Applied Sensor Technologies has a broad selection of standard temperature sensors that are designed for general
Heat Trace RTDs
• Thermowells and protection tubes
A thermocouple is two wires of dissimilar metals joined at one end. Changes in temperature at the junction induce a change in electromotive force (emf) at the other end. Our standard offering includes base-metal (J, K, E and T) and noble-metal (R, S, and B) calibrations.
RTD’s or Resistance Temperature Detectors
An RTD’s resistance increases as the temperature increases. We offer both wire-wound and thin-film designs, depending on the application. Many possible curves are available, from 100-ohm, 500-ohm, and 1000-ohm platinum RTDs in both DIN and American alphas, to nickel-iron and copper curves.
Thermistors rely on the resistance change in a ceramic semiconductor, with the resistance dropping non-linearly with a temperature rise. Many different elements are offered, including the common 10K and 100K curves.
The integrated circuit (IC) temperature transducer provides either voltage or current output and is extremely linear.
