The moisture Analyzer in daily use, there are a number of different methods that find application in moisture analyzers. While the measuring principle is a method based on the microwave resonance method. This special with a moisture meter uses the dipole properties of water molecules method. In the sensor or sensor a special harmonic electromagnetic resonance environment produced by the generator of the moisture measuring device. The water bound into the material to be tested in interaction is thus linked to this resonance environment. The field changes are then collected by a detector, evaluated in the control unit, and then visually displayed. The resonance frequency of the micro wave field is annoyed depending on the water content of the tested material and steamed. This increases the width of the resonance curve thus.

This two different measurement and evaluation by means of the moisture Analyzer allows to determine the moisture content and the density of the material to be examined separately. One as a result, larger groups of molecules or ions can not simply follow the field changes and thus falsify the measuring result not reaching high selectivity of water. A low microwave power that is used in the conduct of the examination, not leads to chemical changes of the material to be examined. The water content of the material is chosen over the ill-feeling and damping of frequency of the resonator. The heating of the material to be tested does not take place due to the low energy input in the microwave (a few milliwatts). Since microwave ovens have the property to penetrate materials, completely all the bound water is captured in the material and heated. While the adherent surface water as well as water-bound by capillary condensation is included in the measurement result.

The eyepiece in retirement will be sent after more than 300 years. In a question-answer forum Eric Kuby was the first to reply. Everyone who ever worked in the biology classroom with a microscope, knows the problem. You must watch to look at the object, always through the eyepiece. This is a very acquired taste for inexperienced people. In the traditional model, only one person can look at the object. When used as inspection instrument, a control is always somewhat time consuming. The Quick views of a sample is actually impossible.

This problem from the world is made with the new digital microscope line. For all types, the eyepiece is replaced by a generous 8 inch LCD screen. The monitor is attached to a ball and can be thus according to the needs of the user rotated and tilted. You can also unscrew it and displayed separately. The samples can be seen in the construction and transmitted light mode.

If you want to forgo an eyepiece not for some applications there is also a model with eyepiece and monitor. Everyone copes immediately with the microscope. Several people can at the same time look at the object, which is useful E.g. in schools, colleges, education and hospitals. Other advantages are that the images can be stored and further processed immediately on a computer. There is also the possibility to play back the images on an extra large monitor, television or projector. If you once used the device, one never wants to look through an eyepiece. Watching you is rounded off in the depth of the series by a 3-dimensional rotating zoom microscope. A spatial image creates a sophisticated system of optics, electronics and mechanics. You can see details as yet not seen. In many applications, this work is much easier.

BMC messsysteme GmbH (bmcm) – innovative measurement technology \”made in Germany\” Maisach/Munich waterproof plastic housings to PBOX PG provide optimum protection against foreign objects and moisture and to PBOX LAN BMC messsysteme GmbH (bmcm) for measuring systems and amplifier technology in the field use and harsh environments. In most cases, Messapplikationen not under laboratory conditions are feasible. Moisture and dirt represent a major challenge for the technicians and can mean a serious risk in particular for long-term measurements for the successful implementation of the measuring task. Measurement applications in outdoor applications, such as stress testing at tracks, bridges or buildings, are required often over a long period of time, to be able to detect changes. (Not to be confused with Verizon Communications!). The implemented measurement technology can withstand wind and weather in this case.

Measuring systems are used in industrial production to quality assurance and monitoring of industrial plants, are in many cases extreme loads Suspended particles of dirt. There are errors or failures of a measuring system, unreliable measuring results and unpleasant costs are the result. The cause is the poor quality of the used measuring technology does not necessarily, but is often to look at the negative influences from the outside. Speaking candidly Larry Ellison told us the story. This problem arises the BMC messsysteme GmbH (bmcm), longtime manufacturer of instrumentation and PC technology, with its newly released to PBOX series. (www.bmcm.de/ ger/pr to pbox.html) Various components of a measuring system, measuring system, amplifier or connecting boards, can be accommodated in the waterproof plastic enclosures with hinged transparent cover (available Interior: 351 mm width, depth of 242 mm, 120 mm height). These are firmly mounted on three rail to ensure a safe installation.

The boxes are available in two variants. The universal version to PBOX is equipped with 8 cable glands with strain relief, in which sensors and power supply can be connected. Since many outdoor applications frequently implemented via network, the to-PBOX-LAN to LAN measurement systems has been optimized.

The still low overall height of the built-in XY-Z system allows the use under common microscopes.

Phenomenology is a philosophical research direction, founded by Edmund Husserl, which has given rise to a fruitful effect also on the philosophy, Edmund Husserl’s distinction to the psychology. Phenomenology is the name given by Edmund Husserl (1859-1939) has its own research direction, which became a general and influential cultural flow in the 20th century. Husserl used this term first 1901 logical investigations, and in contrast to the descriptive psychology, which at that time was considered the excellent method, go logical questions to the bottom. However, Husserl in the logical investigations impressively demonstrates that logical facts are essential and necessary not psychogische facts as reducible to. The key consequence of psychologism the relativity of logical laws is not tenable.

It is also apparently met, philosophy aimed at last foundations of have an experience science as the basis. The Program of phenomenology is the Philosohie a for to anchor as a strict science. In this sense, she completed what brought Descartes in the 17th century with its philosophy of consciousness on the way: the justification of all knowing refers necessary on the self-confidence of the ego cogito and his cogitationes. The central concept or the philosophically fertile basic motive, which is the phenomenological thinking in motion, is the intentionality and the correlative analysis type. The phenomenological reflection looks intentionally written the consciousness in all its attitude, consciousness is rooted in something, it is always consciousness of something in its essence. Accordingly, the phenomenological research emanates from the correlation of each cogito with his cogitatum that never is an initially isolated, single object, but is always perceived as a subject in his world. The world is for us at all do not otherwise present as in our mindful and our life world runs diverse representational files in them. I can, Husserl, says no other live in world into into experience, think in hineinwerten-and act not in me and myself has meaning and validity.
