Although very little current flows, power can be generated by a single thermocouple junction. These can also be utilized in inert or oxidizing atmospheres, however these must not be used in the sulfurous atmospheres, lower oxygen or vacuums for avoiding dangers. 3 inch Cable Length: 60 inch / 1.52m The sensor is at the tip of the 3 inch long stainless steel probe It has a miniature type connector that will work with digital K-type thermometers Package Include: 1 x k-type thermocouple probe They are as follows:1) Seebeck effect: The Seebeck effect states that when two different or unlike metals are joined together at two junctions, an electromotive force (emf) is generated at the two junctions. Displays up to 8 channels at a time. This junction type is popular in the Plastics Industry. The life of a thermocouple is also something to consider, particularly at extreme temperatures and it may be worth considering Infrared Pyrometers instead which can measure temperature from outside the process. Accuracy: The accuracy for R-type is Typical: +/- 1.5C (or) +/- .25% particular error limits: +/- 0.6C or 0.1%. The most common types (calibrations) are J, K, T, and E. Although the thermocouple calibration dictates the temperature range, the maximum range is also limited by the diameter of the thermocouple wire. Disadvantages of the Thermocouples. What is meant by thermocouple junction types Exposed, Ground and Insulated Hot Junction?

The working principle of thermocouple is based on three effects, discovered by Seebeck, Peltier and Thomson. As the name suggests the thermocouple junction in this design is electrically insulated from the protection sheath. The usable temperature range extends from about -250°C (cryogenic) to 900°C in oxidising or inert atmospheres. In practical use, the voltage generated at a single junction of two different types of wire is what is of interest as this can be used to measure temperature at very high and low temperatures.

In 1821, the German physicist Thomas Johann Seebeck discovered that when different metals are joined at the ends and there is a temperature difference between the joints, a magnetic field is observed. Process Parameters offer an extensive range of thermocouple sensor types for a broad spectrum of applications ranging from automotive sensors through to flare stack thermocouples. The most common code letters are K, J, T and N. Other types include R, S, E, B, C, G and W. Each thermocouple type has its own alloy pair which are carefully selected and calibrated to meet the international standards to which we must comply. The thermocouple has the fast response time. The most common type is K (nickel-aluminum and nickel-chromium wires) because of its wide temperature range (from about −200 to 1,260 °C [−300 to 2,300 °F]) and low cost. Also known as Chromel-Constantan, this thermocouple is known for its high output - the highest of the commonly used devices, although this is less significant in these days of ultra stable solid state amplifiers. For example, Type T with its Copper leg has a max temperature of 370C or 700F.
