Palm Paper gets instrumentation for giant machine

26 January 2009

Palm Paper has turned to manufacturer, Vega for level, switching and pressure instrumentation for use in a huge newsprint paper machine.

The machine, supplied by Voith Paper is headed for Palm Group enterprise, Palm Paper’s new mill in King’s Lynn.

The machine, PM 7, is claimed to be the largest paper machine for newsprint paper in Europe. It has a wire width of 11.4mm, a working breadth of 10.6m and a maximum annual quantity of 400,000 tons in the basis weight range of 42 - 48.8 g/m2 using 100 per cent de-inked recycled paper. PM 7 is designed for a maximum production speed of 2,200 m/min. Start-up is planned for the third quarter of 2009.

The order includes, among other things, VEGABAR pressure transmitters with CERTEC ceramic measuring cell, VEGAPULS radar sensors with various antenna types as well as VEGASWING vibrating level switches. The instruments will be used in all areas of the new plant – from stock processing to paper machine. All continuous measuring instruments are communicating via Profibus PA technology.

Palm Paper Limited said it will invest €330 million (£255 million) in the construction of the King's Lynn mill.

VEGABAR pressure transmitters have a range of approvals and designs for chemical, marine, food and pharmaceutical industries and have 0.1 per cent accuracy as standard.

There are three main types of measurement cell the Ceretec Cell is a ceramic cell for chemical and abrasion resistance and overload up to 200 times. The Metec Cell is a hastelloy and stainless, self temperature compensating cell, patented by VEGA for hygienic and high temperatures up to 250°C with no additional chemical seal. Finally, the DMS Cell has a dry metal diaphragm and is claimed to be vibration and shock resistant for pressure ranges up to 600 bar.
