TTB 85

Thermal Barrier

The TTB 85 thermal barrier is used for applications where data loggers need to be operated in ambient temperatures between +200 and 400 °C. The thermal barrier consists of a stainless-steel cylinder with a ceramic insert and stainless-steel lid.

Prior to use, the ceramic material is saturated with distilled water and the data logger is placed inside TTB 85 with only the high temperature sensor(s) exposed through the lid.

TTB 85 provides the following features and benefits:

  • Diameter/height of 85 mm – usable for high gate openings
  • Provides a protection time of 150 minutes at 300 °C – perfect for when a long protection time is required

Also, data loggers that are equipped with a SKY Module can be used in conjunction with the TTB 85 thermal barrier, however, a special SKY kit for thermal barriers is required
