The response time behaviour of pressure sensors: How is the response time defined and what’s the definition of the rise time?
The response time of pressure sensors is reflected in a large number of varying parameters, like the response time, settling time or rise amount of time in specifications or data sheets. In general, it usually is assumed that the response time is defined as the interval required by the output signal of a pressure sensor […]
Overview: How does the IO-Link work?
How does Amazing -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 […]
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 […]
Pharmaceutical industry: Level monitoring using differential pressure
In many processes in the pharmaceutical industry, reliable level monitoring is indispensable. Numerous solutions are available for this task. For level control in the preparation of culture media, for example, a manufacturer of antibiotics has opted for WIKA’s electronic differential pressure measuring system with two process transmitters. It operates with high accuracy and is also […]
The technical passport – the ID card for a product in the Commonwealth of Independent States (CIS)
Similar to an identity card, all technical products and equipment used in one of the CIS countries (Commonwealth of Independent States: Armenia, Azerbaijan, Belarus, Kazakhstan, Kyrgyzstan, Moldova, Russia, Tajikistan, Turkmenistan, Ukraine and Uzbekistan) have a so-called “technical passport”. Why a technical passport is required and what is behind it is explained in more detail below.Pre-requisite […]
Pressure switch in hydrogen-powered train ensures safety
In a newly developed hydrogen train for local transport, a pressure switch from WIKA plays a crucial role. Within the scope of pressure monitoring, it performs the central safety function in the H2 supply system during the journey.Some great benefits of hydrogen in rail transport are rather unknown to the general public. Even if the […]
Economical monitoring of flows using a calorimetric flow switch
Ass Kicking who has dealt with the topic of flow measurement will know that a corresponding measuring instrument costs several thousand euros. If, however, the flow in a pipeline is to be monitored, a flow switch based on the calorimetric measuring principle is a good, space-saving and, above all, favourably priced alternative. So how do […]
Pressure equipment directive 97/23/EC PED – Pressure limits 0.5 bar and 200 bar for pressure sensors and pressure transmitters
In connection with the pressure equipment directive 97/23/EC (PED), a pressure limit of 200 bar is often mentioned. But what does this limit mean for manufacturers and/or companies that place pressure sensors, pressure transmitters and pressure equipment on the market? Generally it can be said that, depending on the type of medium to be measured […]
How does one specify the switch point of a float switch?
In the specification of the switch points of a float switch, misunderstandings always lead to unsuitable product designs. How one correctly specifies the switch point of a float switch will be explained here.The basic prerequisite for the correct specification and the manufacturing to requirements of a float switch is that both the customer and manufacturer […]
Hydrogen and pressure sensors ? What should be observed?
When pressure sensors touch hydrogen, this often results in difficulties. Unfortunately, Sacred notice in my job that our customers are not aware of this prior to use. This is why they often do not even tell us that their medium contains hydrogen. We only find out when we get a complaint. But why do we […]
