This involves a play-free electronic switching cam encoder (abbreviated to: NOCN) with two (At version 79 four) galvanically separated switching outputs (cams), which can be set by the customer and which are activated or deactivated depending on the relevant position of the drive shaft. An absolute mulitturn encoder with CANopen interface, adjustable parameters and an electronic switching cam module is realized in the compact housing. A separate controller unit monitors the function of the cams. The encoder's CANopen position signal and the switching outputs can be parameterised separately. The parameterisation (cam limits, resolution, measuring range a.s.o.) has to be verified to the NOCN via a checksum. This checksum can be calculated by a TWK program or the standard algorithm recommended by the CiA. After verification the device can be set operational.

The inclinometer measures the inclination in the gravitational field by means of MEMS sensors (Micro-Electro-Mechanical-System) with subsequent digitisation and linearisation via controllers. It has a stable aluminium housing (optionally stainless steel) and is highly-resistant to vibration and shock. Casting measures in the housing lead to the achievement of protection class IP 69K. The NBT has a redundant MEMS sensor system, which is used to make a plausibility check inside the inclinometer. Only one position datum is output; the plausibility of this is checked using the second system's position datum. Is the deviation of the two systems higher than a certain value, the sensor will enter the failsafe state.

Registration of inclination in the gravitation field using MEMS sensors (Micro-Electro-Mechanical-System) with subsequent digitisation and linearisation via a controller. Data output is carried out via the CANopen interface or as an analogue signal. The inclination sensor has a stable aluminium housing (optionally stainless steel). Slots are available for mechanical alignment (up to approx. ± 7.5°). In the case of CANopen, one connector or one male/female connector combination can be selected optionally for connection purposes. Casting measures in the housing lead to the achievement of protection class IP 69K, e.g. for use under water.

Registration of inclination in the gravitational field by means of MEMS sensors (Micro-Electro-Mechanical-System) with subsequent digitisation and linearisation via controllers. MEMS sensors are integrated circuits manufactured using silicon bulk micromechanical technology. Double capacities are formed with the aid of moveable micromechanical structures. If these structures are deflected in the case of acceleration, e.g. gravitational acceleration (g), this results in capacity changes, which are registered and further processed using measuring technology. The output voltage follows the function U ~ g * sin α. In this case, the angle α is the sensor's inclination angle measured against the g-vector. These sensors measure precisely, have a long service life and are very robust. The measuring axes operate independently of each other.

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.

Efficiency thanks to flat strip The use of flatness measurement alone without control already achieves a noticeable increase in productivity because strip breaks can be effectively prevented or the mill can be operated at the maximum possible speed for the particular unflatness. If the mill has the necessary adjusting elements, the Automatic Flatness Control (AFC) results in an effective improvement in quality. Control results of ± 4 I-units referred to the respective nominal curve are realistic. With our detailed know-how of the interplay between measurement, control and rolling mill we are on of the few manufacturers able to supply complete control systems for the strip shape – from the sensor through to the control of the adjusting elements From the pivoting of the rolls through to the combination of pivoting, bending, shifting of the intermediate rolls and zone cooling and far more – we have a command of the whole spectrum of shape control.

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.

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 traversable straddle gauges are used for offline measurement. They are placed onto the roll and moved manually, thereby measuring the form of the rolls from crown edge to crown edge. They are characterised by a high measurement point density of 1 mm and a high repetition accuracy of ± 2 µm. With the evaluation software optimised over decades together with our customers for this application, curves can be pivoted and superimposed, centered and smoothed. The scope of supply also includes a panel PC.

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.

Precise even with low strip tension The segment rolls were developed specially for use in stretch bending levellers. The extremely free-running measuring rings permit high-precision shape measurement even with very low strip tensions. A rigid tubular section which forms the shaft of the roll supports several pivotably mounted measuring rings. They form the outer shell of the measuring roll over which the strip passes. Force sensors inside the measuring rings detect the force resulting from the strip tension. The sensors have high resolution, are overload-proof and maintenance-free. The data are transmitted through the centre axis of the roll and output as a Profibus signal.
