MEASUREMENTS, CONTROLS, REGULATIONS

Ubiquitous technologies with versatile requirements Whether in research and development, in modern industrialproduction or even in the home – there is no area in whichmeasurements, control processes and regulations arenot required. Today, there are constantly increasingdemands for data accuracy. At the same time,the operating conditions for measuring and regulation instruments arebecoming consistently stricter,resulting from, for example,temperature changeendurance or aggressive mediums.Owing to their competent high-tech material, technicalceramics made by W.HALDENWANGERhave a tradition of performing strikingly well in a variety of extreme applications. This brochure shows a selection of possible applications within measurement and control technology and delivers important information for engineering and construction of ceramic components. Aluminium oxide ceramic is commonly used to protectdelicate sensors which are in constant contact with, for example, corrosion and other damaging processing substances. Plugs for control lines in nuclear power plants are subject to high radiation; here, synthetic materials were not, or only partially resistant. However, our Alsint 99.7 components are resistant. These Alsint 99.7 components are also faultless in radioactive contaminated areas. As a result of the extreme working temperatures, modern measuring methods such asDTA and DTC require ceramic sheath tubes and other ceramic components – specifically ultrapure Alsint 99.7 is used with DTA and DTC. Laser tubes made of Alsint 99.7 are also used to control the motion sequences of the He-Ne Lasers in harsh operating conditions. Sheath tubes made of various ceramic materials such asAlsint 99.7, Pythagoras, Sillimantin 60 NG, Sillimantin 60, SiC, Halsic-R and Halsic-I, as well as insulation rods made of Alsint 99.7 or Pythagoras, are applied in the field of temperature measurement.Within the processes of controlled engineering, corrosion andabrasion, in connection with high temperatures, can result in extreme operational demands which metallic regulation carrying capacities can not withstand. In such cases, Alsint 99.7 or Zirconia components ensure reliable operations.Technical ceramics reveals its strengths when other materialshave long failed to fulfil necessary requirements. The diversity of design and utilization are therefore nearly limitless.
