Coating Thickness Gauge FSC1/7


The FSC is a non-destructive measurement device for fast thickness measurement of paint and other electrically insulating layers on substrates such as carbon fiber-reinforced plastics (CFRP), CFRP with metallic lightning protection and metals. This mobile device consists of a sensor and a controller for operating and display purposes. The system operates in a non-destructive manner using microwaves in the ISM band without requiring any coupling medium. The FSC Coating Thickness Gauge FSC1/7 is, among other things, used in the aviation industry and is certified for use by renowned aircraft manufacturers.

Coating Thickness Gauge FSC1/7 is used to determine the coating thickness on CFRP and other substrates and has a measuring range of 500 µm. In contrast to other measuring procedures, no minimum thickness is required which enables to detect even low layer thicknesses reliably. The measurement only lasts for approx. 1 second. The scope of supply includes reference films with known thickness based on which the measurement object can be calibrated. The calibration data can be stored and loaded at any time. The measurement can be exported via a USB connection for external further processing.
