The radiometric gauges from Vollmer operate contact-free and measure from a safe distance. They are characterised by their extremely narrow design: With some systems the C-frame is only 120 mm wide.
The X-ray systems from Vollmer have digital detectors which give them extremely low noise values. Vollmer supplies the systems with high-quality ceramic tubes and the necessary cooler.
The isotope systems also have digital detectors. A particular feature of the Vollmer systems is that the radiation source is located in a special tungsten drawer that can be easily removed from the gauge.
Alloy compensation is made either in the classic manner using calibration plates or alternatively at the computer according to the customer's chemical alloy analysis or simply with a small contact thickness gauge that measures the absolute thickness at the start of the pass and transmits this value to the radiometric thickness gauge.
