Insulation Thickness Tester

The insulation thickness gauge measures the thickness of the surface insulation layer of wires and cables using the principles of eddy current or ultrasonic waves. When the probe contacts the insulation layer, it generates an electromagnetic field or ultrasonic wave reflections, and the thickness is calculated based on changes in the signal. It is used for real-time monitoring of insulation layer uniformity on production lines to prevent leakage caused by excessive thinness or material waste due to excessive thickness.
Selection
When selecting, consider the measurement range covering the product thickness and ensuring accuracy meets process requirements. The probe size should be compatible with the shape of the object being measured, with handheld types suitable for sampling inspections and fixed types for continuous production. Environmental resistance should match the workshop's temperature and humidity conditions, and the calibration method should be simple. The data interface should be compatible with the existing recording system.
