Description
Simplex Flameproof Thermocouple is a heavy-duty K-Type industrial temperature sensor engineered for reliable temperature measurement in hazardous environments and continuous high-temperature processes. Built with a premium Inconel 600 protection sheath, this thermocouple offers outstanding resistance to oxidation, scaling, and thermal fatigue, making it an ideal solution for industrial applications where sheath longevity is as important as measurement accuracy.
The thermocouple utilizes a K-Type (Chromel-Alumel) sensing element capable of measuring temperatures from 0°C to 850°C. While this temperature range is similar to stainless steel-sheathed thermocouples, the use of Inconel 600 significantly improves resistance to prolonged exposure in oxidizing atmospheres and repeated thermal cycling. This makes the sensor particularly suitable for continuous-duty furnaces, kilns, combustion systems, and process heating equipment.
Designed for hazardous industrial installations, the AKFS-I6S features a robust flameproof die-cast aluminium terminal head with IP67 protection, safeguarding electrical connections against dust, moisture, and harsh environmental conditions. The 1800 mm insertion length, 6 mm sheath diameter, and adjustable 1/2″ BSP process connection provide installation flexibility while ensuring accurate process temperature measurement.
