DESCRIPTION
Cooperheat’s Automatic Thermocouple Attachment Unit (TAU) enables direct attachment of thermocouples to a work piece using the capacitive discharge method. This technique was pioneered by Cooperheat and has since become a recognised global standard. By reducing the risk of expensive rework, due to thermocouples breaking off during the heat treatment process, this innovation provides a high integrity welded connection which provides reliable and accurate temperature control and recording.
The Cooperheat TAU has a unique automatic operation feature overcoming difficulties associated with manual attachment units which require both hands to operate. Cooperheat’s TAU requires only one hand to operate which is an important safety feature when working at elevated levels or inaccessible locations.
