Critical Technical Advantages
-
Double Ceramic Barrier: The TAF12D utilizes both an outer ceramic thermowell and an internal ceramic sheath. This “tube-within-a-tube” construction provides superior protection against gas diffusion and thermal shock, which are the primary causes of noble metal thermocouple failure.
-
Extreme Temperature Capability: Designed for processes reaching 1,700°C, the TAF12D supports Type R, S, and B noble metal thermocouples. These sensors are essential for maintaining accuracy at temperatures where standard industrial sensors would lose their structural integrity.
-
Non-Porous Protection: The ceramic materials used are non-porous (such as Alsint C799), creating a gas-tight environment. This prevents process gases from “poisoning” the platinum and rhodium wires, which ensures that the measurement remains stable over the long term without drifting.
-
Modular and Replaceable Components: Like other members of the FlameLine family, the TAF12D is modular. Individual ceramic tubes or thermocouple inserts can be replaced as they wear, allowing for optimized lifecycle costs and reducing the need to replace the entire instrument.
-
Specialized Industry Design: The assembly is specifically optimized for applications with high concentrations of contaminants or rapid temperature cycles, such as those found in porcelain production and glass primaries.
-
Redundancy Options: The TAF12D can accommodate either a single or double thermocouple insert, providing a secondary measurement for safety verification or control system redundancy.
