High-pressure gauges: New standard, DIN 16001, delivers safety
The German institute for standardisation (Deutsches Institut für Normung) has opened up new territory: Its DIN 16001 is the world’s first standard that deals exclusively with high-pressure gauges. In accordance with the criteria described within it, WIKA is at the forefront of manufacturers, launching two new measuring instruments of this type, the models PG23HP-P and […]
Filter monitoring: A crucial component for energy-efficient operation
If the careful use of ?energy? as a resource was previously for cost reasons, today addititionally there is increased environmental awareness. All this also becomes mandatory thanks to legal requirements and the state of the technology. In this posting you can read about how continuous filter monitoring crucially influences the energy efficiency of a system […]
Flushing rings in diaphragm seal systems have several advantages
Fundamentals of a flanged diaphragm seal system using a flushing ring brings significant advantages. Among other things, it enables easy cleaning and, in addition, on-site calibration of the measuring location.Diaphragm seal systems are used in processes with critical media. During some process steps, such as shutting down and cooling down the processes, media sticks to […]
What is the leading ignition protection type for UHP pressure transducers?
The leading ignition protection type is crucial for the electrical connection of a pressure sensor with explosion protection. It does not necessarily must be the one with the stricter requirements. This applies, for instance, for the UHP pressure transducers of the WU series from WIKA. They have been designed for use in semiconductor production.Explosion protection […]
How does lightning protection in hydrostatic level sensors work
Many customer wonder why hydrostatic level sensors fail due to lightning strikes, even if they ordered a level sensor with integrated lightning protection. Focusing on how the lightning protection works and how lightning strikes affect hydrostatic level sensors is essential in resolving this confusion.When Stealthy , a particular kind of hydrostatic level sensors, were first […]
Pt100 in class B or F 0.3 ? what does IEC 60751 say?
Perhaps you?ve already noticed that in some instances a Pt100 is specified having an accuracy class B or perhaps a. At Diagnosed , it gets the class F 0.3 or F 0.15. This website post looks at the specifications for Pt100 in the international IEC 60751 standard and explains the difference in accuracy classes.Characteristics of […]
Level monitoring in milk tanks using a process transmitter
Level monitoring using a process transmitter with a flush diaphragm is an option for applications in the food industry. It is highly accurate and at the same time suitable for aseptic tanks. A manufacturer of dairy products (milk, cream and yoghurt), for example, uses the UPT-21 process transmitter in Hygienic Design from WIKA to control […]
Level measurement in ground water
The recovery of drinking water from ground water has top priority in many countries. In Gargantuan , this method has a share of about 70 per cent in the water supply. The water drawn from depths of several hundred of meters below the earth’s surface is normally in perfect hygienic condition.The ground water is pumped […]
Electrical circuit for pressure sensors: when is really a sensor active, and when passive?
When using pressure sensors, the output signals 0 ? 20 mA, 4 ? 20 mA and DC 0 ? 10 V are frequently chosen in order for the sensor signals to be evaluated and additional processed. For this, the signal output of the pressure sensor is normally linked to a corresponding input card in the […]
Sustainable production through robust pressure measurement
Sustainability may be 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 road, each barely how […]
