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.

Thermoresistances (+) brown / red (-) Conventional insulation thermoresistances are manufactured to IEC or DIN specifications, consisting in a platinum or nickel wire coiled on a ceramic or glass insulating core. N Nicrosil - Nisil -270°C / +400°C (1) 0°C / +1300°C (2) --- The number of wires can increase accuracy in measurement. Housing bodies are in Nickel or AISI 304 stainless steel, though AISI 310, AISI 316 or PVC-enamelled bodies are also available for highly corrosive environments. Conventional Insulation Thermoresistances Platinum-wired thermoresistances have a highly linear characteristic, which makes them fit in the temperature range -220°C to 850°C. Less precise thermoresistances are made of Nickel. Their resistance can drift in time, their characteristic is less linear and range is limited to: -60°C to +180°C. (1): wires dia. 0.32 mm. (2): wires dia. 1.63 mm. Maximum temperature of standard cables: 400°C. (+) pink / white (-) Thermocouples, PDF-TCR-011-E-2/10
