Thermal Barriers

Protect data loggers against heat

Datapaq Limited

Designed specifically to provide long-term protection for data loggers even under such extremely tough conditions as those found in vacuum furnaces, DATAPAQ’s TB4600 thermal barriers are suitable for extremely high temperatures up to 1,200 °C.  They withstand repeated heating and cooling cycles, thereby providing maximum protection. Their design is based on an ultra high-temperature grade of alumina-reinforced micro-porous insulation and a phase-change heat sink, both ensuring that the data logger can operate below 70°C. Manufactured from high-grade reinforced Inconel, the thermal barrier casing resists distortion during repeated use at above 950°C. Furthermore, strengthening on both the lid and the base of the casing ensures a positive barrier seal. The barriers are equipped with internal gas flow vents to rapidly equalize the change from vacuum to high pressure gas quenching. Externally removable gas quench deflector shields and taper lock catches minimize distortion during rapid cooling periods, thus ensuring a long service life. The heat sink surrounding the data logger is fitted with high pressure filler seals to resist the high pressures experienced during gas quenching.
