Watanabe TFB [Thermocouple] Silicon Nitride Protective Tube Type with Terminal Box
Made in Japan
Manufacturer: Watanabe Electric Industry Co. Ltd
Model: TFB
TFB is a thermocouple that uses silicon nitride as a protective tube, and is mainly used for temperature measurement of molten aluminum.
Specifications
- Wire type: K.
- tolerance: Class 1, 2, 3
- Number of conductors: single, double
- Temperature measuring junction: ungrounded
- insulation resistance: 10MΩ or more at 500V
Special version
- Built-in converter (4 to 20mA DC output)
*Single element only
Features
- The silicon nitride used in the protective tube of the TFB is a sintered Si3N4 material and is used as a component for molten aluminum.
- What are the characteristics of silicon nitride?
◇Because it is not eroded by molten aluminum, it does not contaminate the molten metal.
◇Decrease in mechanical strength is small in the temperature range of molten aluminum (1000℃ or less)
*Maximum operating temperature is 1250℃
◇ Less adherence of molten aluminum
◇ Can be used without preheating due to excellent thermal shock resistance
*The non-metallic protective tube may be damaged due to impact, etc., so please be careful when installing.
