2-1320934-7, also known as Type "NMA" thermocouples, are non-magnetic thermocouples used to measure very extreme temperatures in various industrial and laboratory environments. The underlying technology is based on thermoelectric effects, which produce a potential difference across two components when one of them is heated, in this case, the junction of two dissimilar metals.

The application fields of Type "NMA" thermocouples are numerous. These types of thermocouples are mainly used in heavy industry to measure the temperature of high-temperature furnaces and boilers, as well as measuring the temperature of industrial gases in the chemical industry. Type "NMA" thermocouples are also common in the automobile and aerospace industries, where they are used to measure combustible exhaust temperatures and the temperature of turbine blades. Additionally, they are often used in food processing machinery to measure the temperature of food products.

The working principle of Type "NMA" thermocouples is based on the Seebeck Effect, which states that a potential difference (voltage) will be present between two dissimilar metal junctions when one of the junctions is heated. The magnitude of the voltage produced is dependent on the temperature difference between the two junctions.

The construction of a Type "NMA" thermocouples consists of two dissimilar metal wires that are twisted together and insulated. One of the metal wires is typically a copper alloy and the other is a chromium-nickel alloy. The resulting thermocouple is inserted into the environment to be monitored and attached to a temperature reading instrument. When one of the junctions of the thermocouple is heated, a small voltage is generated that is proportional to the temperature of the heated junction. This voltage is then measured by the instrument and converted into an electrical signal that can be read as a temperature.

Type \'NMA\' thermocouples are very robust and reliable and are relatively easy to use. They are also relatively inexpensive and have no moving parts, making them ideal for long-term use in extreme environments. Furthermore, they are used in a wide range of industries, from automotive to aerospace, and are reliable in a variety of applications.

In conclusion, Type "NMA" thermocouples are a reliable and cost-effective method of measuring extreme temperatures in industrial and laboratory environments. They are based on the Seebeck Effect and consist of two dissimilar metal junctions that are twisted together and insulated. When one of the junctions is heated, a voltage is generated that is proportional to the temperature of the heated junction. This voltage is then measured and converted into an electrical signal that can be read as a temperature.
