Thickness measurement - Import export

Thickness measurement on plastic film samples requires automatic transport of the film strips through the measuring device, allowing for the flexibility of the material being measured. The desktop version of the VDM measuring station can be equipped not only with the pure measuring device, but also with PC-aided evaluation and graphic representation of the measurement results.

The SQM-160 uses proven INFICON quartz crystal sensor technology to measure rate and thickness in thin film deposition processes. Two sensor inputs are standard and four additional sensor inputs are optional. Two recorder outputs provide analog rate and thickness signals. Sensor inputs can be assigned to different materials, averaged for accurate deposition control in large systems, or configured for a dual sensor. The rate sampling mode allows a shuttered sensor to extend sensor life in high rate processes. Rate displays of 0.1Å/s or 0.01Å/s are user selectable. In addition, Frequency or Mass displays can be selected. Four relay outputs allow the SQM-160 to control source or sensor shutters, signal time and thickness setpoints, and signal crystal failure. Digital inputs allow external signals to start/stop and zero readings.

Proven for decades The contact gauges that measure the thickness of the strip with an accuracy of a few micrometres are renowned for their outstanding precision and exceptional reliability: Almost 2000 systems that have gone into operation worldwide in recent decades are still in use even today. They still form an integral part of the measurement technology in new plants where the highest precision is demanded. Flexible from 0.01 to 24 mm Tactile measurement is employed at all stages of the strip production process – on the annealing line and during rolling, on the finishing line or during strip processing as well as in the steel service centre. Vollmer delivers the systems in different versions for thicknesses from 0.01 to 24 mm. Precise even on wavy strip With a measuring precision of down to one micrometre per millimetre of strip thickness, they meet the demands of modern rolling mills. Contact gauges adapt to the strip passage and follow any waviness of the material.

Proven for decades The contact gauges that measure the thickness / width of the strip with an accuracy of a few micrometres are renowned for their outstanding precision and exceptional reliability: Almost 2000 systems that have gone into operation worldwide in recent decades are still in use even today. They still form an integral part of the measurement technology in new plants where the highest precision is demanded. Flexible for up to 9 mm strip thickness / 32 mm strip width Tactile measurement is employed at all stages of the strip production process – on the annealing line and during rolling, on the finishing line or during strip processing as well as in the steel service centre. Vollmer delivers the systems in different versions. Optional the strip thickness gauge can be equipped with an additional strp width measurement unit.

The high-speed servo-hydraulic control of the mill screwdown closes the loop: The thickness values measured precise to the micrometre form the basis for quick and precise control. Vollmer offers solutions for all control concepts from simple feedback control through to complete mass flow control or Direct gap contol for rolling of wedge-shaped strip and in tandem mills. Vollmer supplies the complete control system – from the sensors through the control technology right up to the hydraulics and the cylinder – from a single source. For our customers that means having just one contact partner – in short: A one-stop solution.

The new standard for precision and speed With the new VTLG Series laser systems, Vollmer is giving strip thickness measurement new impetus: They combine the highest precision with rolling mill-oriented design. Thanks to their unique measuring method, they are suitable for use in cold rolling mills. With a measuring precision of ± 1 µm and scanning rate of up to 80 kHz, they offer the precision and speed necessary for the control of the strip thickness. VTLG systems are the only laser gauges to measure the strip thickness during rolling in the mill, thus opening up completely new possibilities in production and quality assurance for our customers. As with our contact gauges, they measure the thickness irrespective of the alloy – ideal preconditions for use in the rolling mill, but also on the annealing line, in the finishing section, on the strip edge miller or in the steel service centre.

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.

Capacitive proximity switches are contact-free sensors. They detect metallic and non-metallic objects, regardless of whether they move or not. The achievable sensing range of the devices depends on the object material, its dimensions and the response sensitivity, which is set via a potentiometer. The vibration-resistant sensors can be approached laterally or frontally. Capacitive proximity switches are used for presence detection (e.g. sealing detection), positioning (e.g. PET bottles), counting (e.g. plastic caps), level detection (e.g. lubricant) or distance measurements (e.g. thickness measurement) of solid and liquid materials.
