Thermal Barriers

The Datapaq TB45 and TB46 Thermal Barrier series incorporate multiple design features such as additional strengthening at critical points, removable gas quench deflector shields and over center catches to achieve the best possible product life. Internally, the thermal barriers incorporate gas flow vents that allow fast pressure equalization as conditions change from vacuum to high pressure.

The TB45 Series of thermal barriers can operate in temperatures up to 1050°C (1922°F); meanwhile, the TB46 Series features high temperature insulation and an Inconel casing so it can withstand temperatures of up to 1200°C (2192°F).

Software

Every Furnace Insight™ software product is designed to convert your raw data into meaningful information that can be acted on. All three software options provide a clear user interface, context sensitive help screens and wizards to assist novice users. The ability to change the language and email results directly from software enables you to share information across the plant and across the world, whether you’re on a computer or mobile device.

Datapaq TB45/46 Thermal Barrier performance

Datapaq TB45/46 Vacuum Thermal Barrier performance

Datapaq TB45 Application In most applications, the environmental conditions and process parameters in the furnace – such as temperature, duration and atmosphere – drive thermal barrier selection.

Datapaq TB45 Thermal Barriers

The Datapaq TB45 Series is limited to a maximum operating temperature of 1050°C (1922°F) and is intended for use in air or vacuum furnaces and can withstand gas quenching. Typical applications include:

Surveying vacuum furnaces for AMS2750 and CQi-9
The TB45 Series is well suited for to run the temperature uniformity surveys (TUS) required to ensure compliance with AMS2750 and CQi-9, among other pyrometry standards. Using a thermal barrier reduces setup time, as the thermocouples can be attached to the jig while the furnace is still in production.
Vacuum hardening and annealing processes
Able to withstand quench pressures up to 20 Bar, the TB45 Series is ideal for monitoring the core temperature of products that require aggressive cooling. For example, when processing medium/high carbon steels (such as EN24) in a vacuum, high-pressure quenching is needed to achieve rapid cooling.

Datapaq TB46 Thermal Barriers

The Datapaq TB46 Series has a maximum operating temperature of 1200°C (2192°F) and is intended for temperature profiling in the most demanding applications. This series represent our most advanced and robust solution. Typical applications include:

Surveying vacuum furnaces for AMS2750 and CQi-9 (for temperatures up to 1200°C)
The TB46 Series is well suited for the TUS required to ensure compliance with AMS2750 and CQi-9, among other pyrometry standards. The Inconel casing and high-temperature, microporous insulation enables these barriers to be used in surveys up to 1200°C and gas quenched.
Vacuum brazing
When peak temperature exceeds the capabilities of the TB45 Series – such as when copper alloy vacuum brazing cycles reach temperatures of 1120°C – the TB46 Series can be used.
Solution treatment of exotic alloys
Some alloy compositions require solution treatment or homogenizing at temperatures greater than 1050°C. For example, medical devices manufactured from CoCr alloys are typically treated at 1200°C, making the TB46 Series ideal for this application.

Special and Custom Solutions

The experienced engineering team at Fluke Process Instruments has produced numerous thermal barriers for applications, ranging from temperatures of -40°C to 1350°C (-40°F to 2462°F).

Radio telemetry link

Radio telemetry accessory

The Datapaq TP6 radio telemetry system utilizes high temperature radio-frequency technology to allow data transmission from the data logger in real time. As the system travels through the process, product and process temperature data can be viewed, analyzed and reported instantaneously. This technology can be applied to monitoring key thermal processes in most industrial heating applications.
