New Robust Thermocouples Offer Longer Life in Harsh Environments

A thermocouple is now available that offers high performance and longer life in harsh process environments, providing superior resistance to temperature, vibration, impact, corrosion and abrasion.

AEROPAK GREAT from Okazaki Manufacturing Company (Japan) is a thick wall mineral insulated thermocouple cable ideally suited to harsh, high temperature process environments such as incinerators and industrial ovens. The cable can be supplied with a hard coating such as cement or Stellite, which offer superior resistance in other harsh high temperature applications, including heavy oil and dispersion kneaders used in the mixing of plastics or rubber.

The gap between the element and the thick wall sheath is densely filled with high purity magnesium oxide, which prevents any residual air from penetrating the sheath, enabling faster response times compared to conventional thermocouples.
