PTP – temperature probes
The temperature probes they detect and measure temperature variations. They are usually transducers, because they transform the temperature quantity into an electronic quantity.
Bare NTC or PTC thermistors are available or inserted into temperature probes (coating made of various materials). Then there are thermocouples, capable of detecting very high temperatures, and thermoresistances, in particular the classic PT100/1000.
Temperature sensors detect and measure temperature changes. They are usually transducers, because they transform the temperature quantity into an electronic quantity.
They are available:
THEMISTORS coated in resin or glass. They can be NTC (Negative Temperature Coefficient) or PTC (Positive Temperature Coefficient). They are among the most precise sensors in existence and give a very fast response but have a limited range and are fragile.
TEMPERATURE PROBES, i.e. thermistors covered in more resistant material which makes them suitable even in situations of high humidity.
THERMOCOUPLES type B, E, J, K, N, R, S, T and C which can reach very high temperatures and are very economical.
THERMO RESISTANCES (RTD - Resistance Temperature Detector) which typically contain platinum wires wrapped in an insulating support and an external protection sheath. Among the most used are the PT100/1000. They are more expensive than thermocouples and have slower response times but are much more stable and precise.
