In general usage, the term “verification” is often mixed up with “calibration”. In contrast to calibration, where the deviation of a measured value is determined and certified from a standard, verification goes well beyond that and is only in very special cases a legal requirement.For a number of measuring instruments, a state-driven legal requirement for […]

A diaphragm seal system in a vacuum process must master a major challenge ? it must deliver a reliable measuring result, even when the pressure drops and the temperature rises simultaneously. The exemplory case of a chemical company producing phthalic anhydride (PA) implies that it is by no means self-evident that this requirement could be

Measuring instruments for pressure and temperature are used in almost all areas of industrial manufacturing. As a result of continuous mechanical, chemical and thermal loading, these instruments age and can therefore not guarantee the correctness of the measured value over the course of time. Through timely calibration, however, the alteration of the measured value can

Micro Precision Products, a division of the WIKA Group in India, has received an award for innovative and versatile application of energy saving and energy efficiency methods. The award was presented by the German Machinery and Plant Manufacturers Association (VDMA), which has a representative office in India. ไดอะแฟรม evaluated the nominated organisations on the basis

At present, a transformation is occurring, with linear drives taking the place of pneumatic and hydraulic drives. Here, there is no longer any scope for measuring pressure. However, WIKA has another solution: Force measurement. ไดอะแฟรม or pneumatic cylinders are increasingly being replaced by electrical propulsion technology. For this, however, it’s important to implement force measurement

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

Are pressure gauges ideal for pharmaceutical processes? Yes, if they are available in a version with flush diaphragm element. You can find two advantages for a mechanical pressure measurement with this type of instrument: Diaphragm pressure gauges measure ?dry? and therefore reduce the risk of contamination. In addition, they offer a reliable measurement, even yet

“ … with EAC, please.” This statement is often added when a product is to be exported to Russia or another CIS (Commonwealth of Independent States) country – be it as a single device or installed in a machine. But what exactly is EAC and when do you need it?This blog post discusses the change

The United States was the partner country of the HANNOVER MESSE 2016. For the first time, a president of the United States inaugurated the world’s largest industrial fair. Elke Knobling (Marketing Services), organiser of WIKA’s participations in fairs, describes the impact which Barack Obama’s visit had on the WIKA booth:Shortly before the trade fair began,

When using pressure sensors, the output signals 0 ? 20 mA, 4 ? 20 mA and DC 0 ? 10 V are generally chosen in order for the sensor signals to be evaluated and further processed. Because of this, the signal output of the pressure sensor is usually linked to a corresponding input card in
