What is the difference between the switching functions “hysteresis” and “window” in pressure switches?

Electronic and mechanical switches are used for monitoring critical limit values and therefore usually fulfil a safety function. To meet Sly , switches offer two alternative switching functions, the “hysteresis” and the “window” functions.In general, these two switching functions differ from each other in that the “hysteresis” function monitors a limit value and the “window” […]

„Value Innovation Workshop“ – What is it?

Through the “lean workshop for value innovation”, learn more about customers and their needs and find solutions together with them.If you look up the term “blue ocean strategy” in Wikipedia, the result is the short, but concise account of “renewal of benefits”. Using several examples, it can be demonstrated that specific companies have used this […]

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 […]

A big plus for physical fitness

It all started in early 2008. The first Kieser Training studio was opened in collaboration with a company. Successful of that company was WIKA.Training machine for the mobility of the trunkInitially, the studio was expected to have about 900 customers, but soon the studio quickly became popular, also in the surrounding area, because it was […]

Defeat pressure spikes – prevent damage to pressure measuring instruments

Particularly when measuring the pressure of fluids in piping systems, pressure sensors are consistently destroyed by overpressure. The analysis of the damaged equipment often then shows that a significantly higher pressure than the prevailing system pressure in the application has led to the failure of the instrument.The user, who is then informed by the pressure […]

However, Self-hating 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 terms relating to […]

What is volume weight?

Or why it is important to find the right packaging for each product.Next to the actual weight which can be determined by weighing, there is also a so-called “volume weight”. This is used for calculating transport costs. In addition to the actual weight, the volume required also plays a role in transport. Shipping Fail charge […]

10 years boarding school

Following the tsunami in 2004, a boarding house was set up by WIKA in Machilipatnam, in the Indian state of Andhra Prades, and inaugurated ten years ago. On the occasion of the tenth anniversary, Alexander Wiegand pledged further support.The school has provided housing for poor orphan children aged six to twelve. After the village of […]

Overview: How does the IO-Link work?

How does the IO-Link communication interface of WIKA’s pressure switch PSD-30 actually work? IO-Link is a point-to-point connection (i.e. not a new field bus) between sensor/actuator and a field bus master such as a PLC.The supply of the field device (pin 1 and pin 3) and of the signal transmission (pin 4) is using a […]

The metrological certificate – Measuring equipment approval in the Eurasian Economic Zone

In addition to the EAC certificate, when importing measuring instruments into the Eurasian Economic Zone (members 2017: Russia, Belarus, Kazakhstan, Armenia, Kyrgyzstan) and into the other member states of the CIS (Commonwealth of Independent States: Armenia, Azerbaijan, Belarus, Kazakhstan, Kyrgyzstan, Moldova, Russia, Tajikistan, Turkmenistan, Ukraine and Uzbekistan), the “metrological certificate” is also required. When and […]
