Ultra Sonic thickness measurement
Ultra Sonic thickness measurement
(OP)
Hi Guys.
Anybody used Ultrasonic thickness gauges ?
I would like to purchase an off the shelf gauge, so I can automate the loading and unloading of the part to be measured and send the result to a GUI.
The max thickness to be measures is 5mm
surface could be alu or FE
1. As I would like to automate the loading , how critical is part presentation to the probes ?
2. Do you need to calibrate against a known master ?
3. What is the typical resolution/accuracy and what cost ball park figures.
4. Is the measurement effected by coatings on the material to be measured (usually a think film of varnish 3microns thick.)
Thats all for now sorry if I posted in wrong section
Confused

RE: Ultra Sonic thickness measurement
2. Usually the device comes with a calibration standard
3. Accuracy can be around +/- 0.025 mm, cost can be around $1000
4. The thin coating you mention should not present a problem
RE: Ultra Sonic thickness measurement
Obviously, if you have the opprtunity yo calibrate, it enhances accuracy (enormously)
there seems to be devices that can acocunt form coatings. I know of one surveyor that has one, but i have no experience with it.
