Press-on labels sense machinery heat

Non-reversible temperature-recording labels show signs of heat build-up in machinery.

A Fullerton, Calif., company has developed press-on labels that can be used to indicate excessive temperatures in machinery and as signals for the need for maintenance. Telatemp ( says its non-reversible temperature recording labels can be used to show signs of heat build-up from worn bearings, low fluid levels, fluid contamination or excessive loads. The labels provide immediate visual indication of abnormal conditions.

The labels are designed to measure temperature increments of 50-degree F through an array of six, sealed sensing windows. The windows are calibrated in ten-degree increments. When the surface temperature reaches the temperature of the particular window, the indicator permanently turns black and provides a visual record of the highest temperature reached.

The labels are available in a series of ranges from 100 degrees F (38 degrees C) to 500 degrees F (260 degrees C). Each label is printed in both degrees Fahrenheit and degrees Celsius, is self-contained and requires no electrical or mechanical activation.
