Handheld thermal imagers for predictive maintenance & high-temp fault-finding

July 28, 2015 // By Graham Prophet
Keysight Technologies has added two higher temperature models to its thermal imagers portfolio. The U5856A and U5857A can perform temperature measurements up to 650 and 1200C respectively. This allows users to detect a wide temperature range for various applications such as petrochemical and steel processing, electrical and mechanical applications, building maintenance and electronics applications.

The U5850 series allows technicians and engineers to efficiently and safely detect abnormalities without shutting down the system. Keysight’s U5850 series TrueIR thermal imagers is among the first in its range of thermal imagers that include four times in-camera fine resolution of 320 x 240 pixels from a 160 x 120 pixel detector. Together with the manual focus feature, this allows users to focus on an object as close as 10 cm, for clearer, sharper images.

The U5850 series offers image logging and temperature trending capabilities to monitor temperature changes overtime for accurate quality checks and diagnostic purposes. With 0.07C thermal sensitivity, users can capture, save and analyse temperature changes accurately. For more in-depth analysis and report generation, technicians and engineers can use the TrueIR Analysis and Reporting Tool PC software, which they can download free at www.keysight.com/find/TrueIR_ART

The U5855A’s compact, light and ergonomic design allows engineers to comfortably use the thermal imager for longer periods of time, and operate it single-handedly in tight locations. Users can also change settings or access frequently used functions such as flash light, laser pointer, auto scaling or simply capture thermal image with quick access buttons. With a customisable colour palette, users can now set specific representations for their applications. A video is here.
