RS PRO 239-4599 Type K Mineral Insulated Thermocouple is a high-performance temperature sensor designed with a 250 mm length and 3 mm diameter probe suited for industrial, laboratory, and manufacturing process temperature measurements ranging from 750 °C to 1100 °C.
The thermocouple's probe sheath is made from 310 stainless steel with mineral insulation, offering excellent flexibility, mechanical strength, and corrosion resistance. Its insulated hot junction minimizes electrical interference ensuring accurate and stable temperature readings. The thermocouple is equipped with an M8 x 1.00 mm fine pitch threaded pot seal, rated up to 200 °C, and a 100 mm long cable for convenient installation.
Mineral insulation, composed of compacted magnesium oxide powder, protects the thermocouple wires from environmental damage and promotes prompt thermal response. The probe complies with JIS standards, ensuring quality and reliability for critical temperature sensing operations.
Thermocouples operate based on the Seebeck Effect, where a voltage generated between two dissimilar metals responds to temperature changes at the measurement junction. The insulated type K thermocouple provides a stable reference and measures extreme temperatures efficiently, making it suitable for automation, HVAC, manufacturing, and laboratory applications.
The thermocouple has an insulated hot junction to reduce electrical interference. Mineral insulation allows the probe to bend flexibly while providing environmental durability. The probe sheath resists corrosion and oxidation due to high-quality 310 stainless steel.
M8 x 1.0 mm fine pitch threaded pot seal enables secure installation with temperature resistance. The 100 mm cable and cable terminal type support simplified connectivity. Complies with JIS standards ensuring consistency and reliability.
Probe length of 250 mm and diameter of 3 mm accommodate precise temperature measurement.
This mineral insulated thermocouple is ideal for use in industrial automation, control systems, and harsh environmental conditions requiring reliable temperature sensing.
