Critical Technical Advantages
-
Extreme Temperature Capability: Designed to handle a broad thermal range from –40 to +1,100 °C (–40 to +2,012 °F), the TC65 is the preferred choice for combustion processes, high-temperature reactors, and exhaust systems where standard RTDs reach their physical limits.
-
Comprehensive Hazardous Area Protection: The device is certified for global safety standards with multiple protection types, including Intrinsic Safety (Ex ia), Flameproof (Ex d), and Non-Sparking (Ex nA). This makes it suitable for the most volatile zones in refineries and chemical plants.
-
Design Compliance (DIN 43772): The measurement inserts and mechanical configurations follow DIN 43772 standards, ensuring a high degree of interchangeability and compatibility with existing thermowells and plant infrastructure.
-
Flexible Installation: The TC65 can be installed using fixed threads or sliding compression fittings. The sliding fitting is particularly useful for fine-tuning the immersion length on-site or for accommodating thermal expansion in high-heat vessels.
-
Enhanced Signal Reliability: By utilizing an optional iTEMP head transmitter, the device converts the millivolt TC signal into a stable 4 to 20 mA or HART signal right at the measuring point. This significantly reduces measurement errors caused by long extension wires and electromagnetic interference.
-
High Environmental Resistance: With an IP68 protection rating and a static pressure capability of up to 75 bar (depending on the connection), the TC65 is built to withstand outdoor exposure, heavy washdowns, and high-pressure process conditions.
