Critical Technical Advantages
-
Triple Layer Protection: The TAF12T provides three distinct barriers between the process and the platinum/rhodium thermocouple wires. This triple-tube architecture is specifically engineered to minimize gas diffusion and chemical “poisoning” of the sensor, which is common in glass and ceramic production.
-
Maximum Gas Tightness: By combining different grades of non-porous ceramic (such as Alsint C799), the assembly creates a hermetically sealed environment for the noble metal wires. This prevents drift and maintains high measurement accuracy over an extended service life.
-
Thermal and Mechanical Resilience: The multi-sheath design offers superior resistance to thermal shock and mechanical wear. While the outer tube handles the direct chemical and abrasive attack of the furnace atmosphere, the inner tubes provide a stable, vibration-dampened environment for the sensitive thermocouple elements.
-
Support for Type R, S, and B Sensors: The TAF12T is compatible with all high-temperature noble metal thermocouples. These sensors remain accurate at temperatures where standard base-metal thermocouples would rapidly melt or oxidize.
-
Modular Cost-Efficiency: Despite its complex construction, the TAF12T follows a modular design. Each of the three ceramic tubes and the thermocouple insert can be replaced as individual spare parts. This allows plant operators to replace only the outermost worn components, significantly reducing total lifecycle costs.
-
Versatile Configuration: Available with single or double thermocouple inserts, allowing for simultaneous process control and redundant safety monitoring in critical baking or melting zones.

Primary Applications
-
Glass Melting and Primaries: Monitoring the most aggressive zones in glass tanks where alkaline vapors can quickly penetrate single or double-layered sensors.
-
Specialized Porcelain Production: Controlling the firing cycle in high-end ceramic kilns where even minor sensor drift can lead to batch rejection.
-
Brick and Tile Manufacturing: Providing long-term stability in continuous tunnel kilns with high dust and abrasive particulate flow.
-
Refractory Material Testing: Used in research and development for testing new high-heat materials where 1,700°C stability is required.
-
Hazardous Waste Incineration: Measuring combustion temperatures in environments with highly corrosive flue gases that require a triple-barrier defense.
