Pull-wire emergency stop switches are mounted on machines and sections of plants which cannot be protected by guards. In contrast to mushroom head Emergency Stop push buttons, on pull-wire switches the Emergency Stop command can be initiated from any point on the wire.
In combination with one of the AES and AZR range safety monitoring modules, see chapter 10.3, ZS range pull-wire emergency stop switches can be used for Control Category 3 or 4 to EN 954-1.
Design and mode of operation:
All of the pull-wire emergency stop switches conform to European Standard EN 418. They have a positive linkage between the NC contacts and the wire rope. The pull-wire emergency stop switches are brought into the operational condition by pre-tensioning the wire, i.e. the NC contacts are then closed and the NO contacts open.

Pizzato Elettrica has designed and patented new accessories to install the rope of safety switches faster and to obtain an aesthetically more pleasant system.
The new accessories, in comparison with the traditional fixing system through carpentry material, have the following advantages:
%u2022 The installation is faster because only one screw is used for the fastening of every rope extremity, and the parts are prepared to ease the installation. Some practical tests have pointed out that the installation time is halved, reason for which it is named FAST.
%u2022 The system is aesthetically pleasant, because thread parts (which sometimes tear operators%u2019 dresses) and the rope extremities, usually fixed by heat-shrinkable sheath or adhesive tape, have been hidden.
%u2022 The red plastic covers of the fixing parts have been developed also for the function of controlling the rope clamping. If the rope fastening screw is not fixed tightly enough, the cover cannot pass.
%u2022 The rope is fixed without folds, thus reducing the rope stabilisation time and the possible re-calibrations of the rope tightening.
Furthermore two sturdy pulleys has been introduced in applications where the rope is very long in order to support the rope length or to bend its route. They are designed to avoid any deformation and to allow the rope to remain in its seat also when it is energetically activated.

‘Becoil’ knitted mesh demisters.
In many industrial processes it is necessary to remove mist or spray droplets from air or gas streams in order to purify the gas, remove liquid which would contaminate the subsequent process, damage downstream equipment, constitute an undesirable atmospheric emission, or to recover a useful liquid product of the process.
'Becoil' Demisting Units are separators of the impingement type consisting of multiple layers of fabric knitted from metal or plastic monofilaments, crimped and than assembled so that the crimps cross in successive layers. Pads fabricated in this way have a very uniform voidage with an extremely high ratio of filament surface area per unit volume of pad.
Collected liquid in the mesh forms discrete droplets on the filaments which fall off as the force of gravity overcomes the combined forces of the rising gas and surface tension, which tend to hold the droplets to the filament.
'Becoil' Demisting Units have been specially designed to achieve highly efficiency removal - up to 100% on entrained droplets above 5 microns in size, while generating low pressure losses and are virtually maintenance free.

Stainless Steel Filter Elements:
Stainless steel filter elements are made up of several layers of 316 mesh that are sintered together to form an integrated porous element. The middle mesh is of very fine gauge and determines the filtration efficiency of the elements. This layer is then overlaid with inner and outer layers of coarser mesh, to give support and protection.The elements are a typical surface filter and the contaminants are retained on the surface of the filtration layer, this makes cleaning and back flushing a simple process. These filter elements should be ultrasonically cleaned to give best results. Stainless steel filter elements are particularly useful in heavily contaminated applications and for use as pre-filters before disposable
type final filters. Gaskets are required with stainless steel filter elements. The options are Viton, PTFE or high temperature annealed copper.

Filtering liquids or air in hostile environments-such as those subject to temperature extremes, high orders of shock/vibration, and caustic fuels or fumes-has posed problems for paper filter elements. These types of elements simply will not withstand these types of operating conditions.
Metal Textiles knitted wire mesh liquid and air filters overcome the limitations and deficiencies of these and many other filtration methods. Where resistance to degradation, corrosion, mechanical, or thermal shock is desired%u2014and where a resilient product is needed for proper cavity fit%u2014Metal Textiles filters provide an economical, robust alternative. From cryogenic operating conditions up to temperatures of 650° C, knitted wire mesh filters maintain their integrity even when subjected to extremely high vibration and exposed to destructive gases such H2, SO4, and HNO3.
Metal Textiles Knitted Mesh%u2014A Superior Alternative to Paper or Sintered Metal

Constant Temperature Anemometry (CTA) - Hot-wire anemometry
Measurement of flows with very high turbulence and the study of flow micro structures
Hot-wire Anemometry or Constant Temperature Anemometry (CTA) is a point-measuring technique appropriate for the measurement of time series in 1, 2 or 3-dimensional gas and liquid flows.
CTA is particularly suitable for the measurement of flows with very fast fluctuations at a point (high turbulence) and the study of flow micro structures, where there is a need to resolve small flow eddies down to the order of tenths of a mm.
