Pt100, Pt1000 or NTC ? that is the right sensor?
Especially the machine-building industry often asks me which is the proper measuring element for them. This is why why I want to explain on this page the differences between your most commonly used sensors Pt100, Pt1000 and NTC. I will go into greater detail about the lesser-used measuring elements Ni1000 and KTY sensors in the […]
Ingress Protection for Pressure Sensors – Definition of IP protection types
A frequently recurring question is about the definition of the so-called IP protection types or sometimes referred to as “IP rating”. The IP ingress protection types provide a system that describes how the housing of electrical equipment is protected against the ingress of particles/ dust and water.Actually, the standard only describes – by means of […]
Sustainable production through robust pressure measurement
Sustainability is the megatrend for the several-hundred tyre plants worldwide. Among other things, this includes increasing both energy and production efficiency by avoiding rejects while simultaneously shortening production cycles.Sustainability ? already during productionDespite all of the electronic aids, a car today still has only four points of connection with the street, each barely how big […]
Float switch: The facts and so how exactly does it actually work?
Float switches are simple, universally applicable and exceptionally reliable. It isn’t a coincidence that, today, float switches still represent probably the most frequently used principle for level monitoring. But how does a float switch really work?Float switches, in a straightforward mechanical form, have already been in use for the control of water flows in mills […]
Culture Prize for a master’s thesis supervised at WIKA
Marvin Goetze, a graduate of TH Aschaffenburg has been awarded the Bavarian Culture Prize in the Science category for his master’s thesis. His subject was the simulation of energy needs along the value chain. He conducted his case study at WIKA in Klingenberg.“Development and evaluation of a method for the differentiation and simulation of energy […]
Fittings for pressure gauges: mitigating the effects of dynamic load cycles
In several processes, pressure gauges are temporarily subjected to heavy loading. Dynamic load cycles, for example, can permanently damage the measuring instrument. This can be prevented by mounting the appropriate Fittings.Dynamic load cycles often result from pressure surges from a pump. They are visible on pressure gauges as pointer fluctuations. The result of such load […]
China Compulsory Certification (CCC) for electrical thermometers
The “China Compulsory Certification (CCC)” is a certification system of the People’s Republic of China. Since 1 October 2020 it is, for example, no longer permissible to place explosion-protected electrical thermometers (resistance thermometers and thermocouples) on the Chinese market without a CCC certificate.Introduced on 1 May 2002, the CCC certification system applies to imported and […]
Handball player from Ukraine (16) trains with premier league side
What does a talented handball player who’s had to leave his homeland do? Maksym, a 16-year old from Ukraine, shares accommodation with other Ukrainian refugees in WIKA’s plant 3 in Klingenberg. In the meantime, however, he is training at TV Großwallstadt – thanks to a WIKA employee.Kerstin Wüst found out about the young man at […]
Accuracy of pressure sensors – what ”precisely” does this mean?
How is the accuracy of pressure sensors actually defined? The deviation of the actual characteristic curve from the ideal one is often referred to as “accuracy”. However, the term itself cannot be found in any national or international standard. This means that there is no such thing as “accuracy”, but instead a large number of […]
Diaphragm seal system detects level in PTA reactors
Diaphragm seal systems are ideal for many processes in the chemical industry as a resistant and safe measuring solution, for example, to monitor the level in a reactor using differential pressure. Precisely for this task, a manufacturer of terephthalic acid (Purified Terephthalic Acid, PTA) uses such a measuring arrangement with an integrated differential pressure transmitter. […]
