Thanks man

thermowell is a well where u place the sensor like rtd or transducer like thermocouple.

we cant directly insert the rtd into the process media.

"What is the difference between rtd,thermowell and temperature element?"

Ever take biology? Remember taxonomy, the term used to describe how living things are categorized, ie KPCOFGS? Stands for Kingdom, Phylum, Class, Order, Family, Genus, Species. So we humans are Homo (Genus) Sapiens (Species)

Temperature Element is like the GENUS of device

RTD is like the SPECIES of device within that Genus

Thermowell is just where the Genus is placed, regardless of the Species, like house or cave (because Homo Habilis and Homo Erectus are in the same Genus as us).

OK, I think I've waxed off into never never land enough for today...

>taxonomy, the term used to describe how living things are categorized, ie KPCOFGS? Stands for Kingdom, Phylum, Class, Order, Family, Genus, Species.

I'd move them all up a rung, element in family, RTD-T/C-thermistor in Genus, Type K-J-T-E-R-S, various RTD alphas in species.

Then there's the trick of identifying the different genders.

A thermocouple must be a female due to its larger range of uncertainty, its greater tendency to drift, and its intrinsic need for compensation to make any sense of its utterings. It isn't considered functional unless it is tethered to its host through a connection of its own species.

Whereas the male RTD just needs a little excitation through commonly available connections and yields a far more certain response.

Thermistor evolution has yielded some with a positive orientation, others with a negative orientation. They're not renowned for linearity, but due to their reproductive rates have widespread presence in relatively non-demanding, temperate climates.
