In the simplest form, this could mean just a bare wire design or the junction can be constructed so that it extends out the end of a protection sheath. There are four common calibrations of thermocouples, J, K, T and E, each of which is suitable for a different temperature range. 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. A grounded thermocouple has the thermocouple electrically connected, or grounded, to the protection sheath, normally by welding or silver soldering so that it becomes an integral part of the sensor tip. 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. Common types include J, K, L and T. The letters refer to the type of materials used and therefore the temperature they are usable at. These cookies do not store any personal information.
