About Thermocouple Temperature Probes

Thermocouple temperature probes are bimetallic probes that are used in various temperature-sensing applications. They consist of two wires, each of which is made of a different metallic element or alloy. The wires are joined at one end to form a measuring junction that is exposed to the fluid or medium under measurement. The other end of the wire is terminated at a reference junction. Current flows through a circuit when the two junctions of thermocouple temperature probes are at different temperatures. The voltage resulting from this current flow is then measured to determine the temperature.

RTD Temperature Probes
RTD temperature probes convert the RTD resistance measurement to a current signal, eliminating the problems inherent in RTD signal transmission via lead resistance. 
Temperature Probes
Temperature probes are used in various temperature sensing applications. Technology options include thermocouple, RTD, thermistor and solid state style probes.
Thermistor Temperature Probes
Thermistor temperature probes sense temperature by using thermistors, devices made of semiconductor materials which exhibit a large change in resistance for a small change in temperature.
