    Thermocouple Thermal Resistance Temperature Sensors - Overview

    Thermocouple (T/C) Thermocouple sensors are made from two wires. Each wire is a different type of metal. These are then welded together to form a measuring/hot junction. This junction and the wires are usually enclosed in a protective metal tube which is inserted into the medium where the temperature is to be measured. The opposite end of the two wires is also joined, and that point is known as the cold junction. As the temperature at the measuring junction changes, thermal current movement occurs between the hot and cold junctions, generating an electron flow. The measurement of this electron flow can then be referenced to a formula, which converts the reading to °C or °F.  The thermal current motion of a thermocouple relates directly to the types of wires used.

    RTD platinum resistance: is a sensor whose resistance changes as its temperature changes. The resistance increases as the temperature of the sensor increases. The resistance vs temperature correlation is well established and is repeatable over time. The temperature is measured with the resistance of pure metal wires, and the resistance increases at a fixed ratio as the temperature increases. Resistance thermometers are made of platinum, nickel, or copper - with platinum being more commonly used because of its stability and reproducibility.

    Thermocouple thermal resistance temperature sensor specifications and sizes can be customized according to different needs.
