RS PRO 787-7721 Type K Mineral Insulated Thermocouple features a 1.5 m long and 1.5 mm diameter probe constructed with 321 and 310 stainless steel, offering high corrosion and oxidation resistance. It measures temperatures ranging from -40 °C up to a maximum of 1100 °C, suitable for a wide range of industrial applications including manufacturing, HVAC systems, laboratory instrumentation, and process control.
The probe design includes mineral insulation with a highly compacted magnesium oxide powder that electrically isolates the thermocouple wires while allowing rapid thermal conduction. This insulation also ensures resistance to environmental damage and electrical interference, supporting accurate temperature measurements.
This thermocouple sensor complies with IEC 584 Class 1 tolerance standards, offering reliable and precise temperature readings. It features an ungrounded insulated hot junction, reducing electrical noise and ensuring a stable output signal. The plain pot seal enhances durability with a temperature rating of 200 °C, and the bare tail terminal along with a 1 m PFA insulated lead cable offers flexible connection options in various installations.
Mineral insulated thermocouples like this model are widely used in applications where durability, electrical noise immunity, and fast response times are critical. Typical use cases include industrial process monitoring, laboratory testing, HVAC temperature sensing, and control gear integration.
The probe boasts durable stainless steel sheath construction for longevity. Class 1 IEC 584 tolerance guarantees measurement precision. Mineral insulation improves response time and protects wiring. High temperature and low temperature sensing capabilities cover diverse needs.
Flexible design allows for customized probe bending to fit environments. Conforms to RoHS compliance ensuring material safety. Suitable for industrial, laboratory, manufacturing, and HVAC sectors. Comes with 1 m cable length and bare tail terminals for versatile connectivity.
