Temperature Profiler Evaluates Aluminum Vacuum Brazing Furnaces

(Fluke Process Instruments)

Fluke Process Instruments’ Datapaq Furnace Tracker is a dedicated temperature profiler for aluminum vacuum brazing furnaces. The system automatically generates CQI-9 and AMS 2750E reports and is designed for frequent use, even during normal production.


The data logger traces product temperature profiles via ten thermocouples throughout all process phases. Thermal protection is provided by a phase-change heat sink and a thermal barrier consisting of nine stainless-steel and aluminum reflective plates with a ceramic outer coating. The all-metal construction eliminates the need for micro-porous insulation and therefore minimizes outgassing along with its related problems of oxidation and unnecessary rejects. T


he Datapaq VB1150 vacuum barrier protects the logger for 3.5 hours at 600°C. The maximum operating temperature in vacuum processes is 700°C. After 45 minutes of cooling down, the system is ready to be reused.


System software enables trending analysis and facilitates logger diagnostics. It allows users to identify hot and cold spots and optimize product load and furnace parameters such as brazing times, max/min temperatures, and temperature slopes to ensure that all products meet thermal specifications. An optional radio module enables real-time process control, allowing users to adjust furnace settings and ramp-up to the next zone at the right time.
