Temperature-sensing labels

Non-reversible labels indicate abnormal conditions due to heat build-up on worn bearings, low fluid levels and contamination, and excessive loads. They suit temperatures from 100° to 500°F and measure a 50°F range through six sealed sensing windows that are calibrated to 10° increments and turn black when high temperature reached.
