Infrared furnace camera doubles-up as PM inspector

A Flir Systems product story
Edited by the Engineeringtalk editorial team Jul 9, 2009

The Flir GF309 is a portable infrared camera designed to inspect furnaces, but it can also be used for powder metallurgy (PM) inspection.

The camera is equipped with a mid-wave flame filter specifically engineered for high-temperature inspection.

The Flir GF309 provides temperature readings across the entire surface of the heater, boiler and furnace without the need to interrupt the process

As well as being able to see through flames, it can be used for high accuracy electrical and mechanical inspection.

Suitable for monitoring all types of gas-fired furnaces, chemical heaters and coal-fired boilers, the Flir GF309 measures temperatures from -40C to +1,500C with an accuracy of +/-1C across the range.

To protect the camera and the operator it has a contoured, nickel-coated heat shield to reflect heat.

It is suitable for a range of extreme temperature applications including inspecting tubes for reduced heat transfer due to scale build-up.

Overheating tubes, not detected by thermocouples, is another application example.

If left unchecked, localised tube failure will follow resulting in increased process cost.

The Flir GF309 provides temperature readings across the entire surface of the heater, boiler and furnace without the need to interrupt the process.

It allows inspection to be accomplished faster and safer, averting unscheduled shutdowns and costly catastrophic failures.

This ability is complemented by this model's wide operating temperature range and detachable heat-shield.

As a result, the Flir GF309 can be used for other electrical and mechanical inspection tasks from predicting the life of a bearing to spotting poor electrical connections.

In common with other cameras in the GF-Series, this Sterling cooled furnace inspection camera has built-in GPS that automatically documents satellite coordinates, enabling swift identification of the problem site and improving repair logistics.

It also has a high sensitivity of <25mK so that small faults can be seen at a good range.

Additional features include an in-built visual camera and a lamp for use in dark environments.

The Flir GF309 weighs 2.4kg and has a high-performance tilting viewfinder.

This can be adapted to the individual user and is particularly effective outdoors as it shows a very sharp image without the influence of ambient light or reflection.

A turntable control grip allows the camera to be used in the most comfortable position; programmable direct access buttons and joystick control are integrated into this handle.

The choice of automatic or manual focus with 1-8x continuous zoom allows the users to achieve the optimal view.

Images are stored in Jpeg format onto removable SD or SDHC memory cards and the model also has burst recording capability.
