In 1821 T. J Seebeck observed the existence of an electromotive force at the junction formed between two dissimilar metals (Seebeck effect)

A #thermometer is an instrument that measures the #temperature of a system in a quantitative way.
#Thermowells are used to provide an isolation between a #temperature #sensor and the environment, either liquid, gas or slurry.
#Thermocouples are available either as bare wire ‘bead’ #thermocouples which offer low cost and fast response times, or built into probes.
The 4 wire #RTD configuration increases the #accuracy and reliability of the resistance being measured. #Temperature #Sensors
When protected by compacted mineral insulation & appropriate outer sheath, Type J #Thermocouples are useable from 0 to 816°C, (32 to 1500°F)
Temperature is a physical property of matter that quantitatively expresses the common notions of hot and cold.
Bearing temperature is primarily important because bearings are the critical links between the rotating and... fb.me/TPFJACUi
Type R, S and B #thermocouples are known as Noble Metal Thermocouples because they are made of Platinum and Rhodium. #temperature #sensors
Type S- #thermocouples are constructed using one wire of 90% Platinum and 10% Rhodium and a second wire of 100% platinum. #temperature #tmc
A basic physical property of a #metal is that its #electrical resistivity changes with #temperature. All #RTD's are based on this principle.
