Thermocouples & Thermoresistances Temperature probes are basically two wires with particular thermoelectric features, electrically insulated from each other and from the external protection body. This type of temperature gauge is very reliable and quickly responding. Depending on their various construction features, they are individually optimized to fully fit in a great number of industrial applications. The most significant input data needed to design a temperature probe are operative temperature range and working conditions. MgO-insulated thermocouples are made of two or more wires, inside a highly compacted MgO insulation powder. Various materials can be used for the external metallic body, according to the specific working conditions. MgO- insulated thermocouples are manufactured and tested according to ASTM E608, and comply to ANSI MC 96.1 or Conventional Insulation Thermocouples The thermocouple leads are inserted in ceramic insulators, that are housed, together with alumina powder, in protective bodies to ANSI/DIN specifications. The main application of these temperature gauges is when no vibrations, mechanical stresses or pressure loads are applied. Thermocouple Junction Types There are 3 types of wire junction in thermocouples. The type shall be chosen according to the characteristics of the application. The below comparison chart might help.

Thermocouple Types Thermocouples are supplied in various types, depending on the materials of wires, according to ANSI MC96.1, DIN 43710 or other regulations. The different types have different physical and electrical characteristics, making each of them fit for a specific type of application. Types are defined by a letter. While ordering a thermocouple, the standard of reference (typically ANSI, DIN or IEC) shall be specified. Operational Range Electrical Signal Maximum temperature of standard cables: 400°C. PT 1000 thermoresistances are made of materials whose resistance depends from temperature....
