Non-contact displacement sensors from Micro-Epsilon offer numerous advantages in thickness measurement. Capacitive sensors, for example, have a relatively large measurement spot that compensates for inhomogeneous structures. Furthermore, capacitive sensors can be used at high temperatures. Thanks to integrated temperature compensation, the sensors deliver stable measurements in the submicrometer range and can also be used in drying processes.
In the case of optical thickness measurement, confocal chromatic sensors really come into their own, as do white light interferometers for the inline thickness measurement of battery films. The sensors are typically used to monitor and control wet coating processes, but are also suitable for dry coating processes.
You can be sure of the best sensor for the measurement task at hand, no matter what measuring object or type of coating (uncoated/coated) is involved. Just get in touch!
