Pressure gauges for pharmaceutical processes: Flush-mounted ?dry measurement?

Are pressure gauges ideal for pharmaceutical processes? Yes, if they are obtainable in a version with flush diaphragm element. There are two advantages of a mechanical pressure measurement with this type of instrument: Diaphragm pressure gauges measure ?dry? and therefore reduce the threat of contamination. In addition, they offer a reliable measurement, even in critical … Read more

Force measurement in linear drives

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

How does hydrostatic level measurement work?

When considering a new level sensor for level measurement applications, it is often hard to find information on how the different types of level sensors, like the hydrostatic level sensors respectively hydrostatic pressure sensors, are working. Recently, I explained level measurement by using hydrostatic pressure measurement“What does one mean by hydrostatic pressure and hydrostatic level … Read more

Overload safety of Bourdon tube pressure gauges

The question occasionally arises, in connection with Bourdon tube pressure gauges, about the overload safety of the instruments. This article deals with exceeding the measuring range by up to 30 %. What happens with the pressure gauge? Does it still indicate precisely afterwards? Can it start to leak? As a next step, we should shed … Read more

What does RoHS really mean?

RoHS is an abbreviation for “Restriction of (the use of certain) Hazardous Substances”. In accordance with the European Union’s RoHS directive, the restriction relates to the use of such substances in electrical and electronic equipment. Its objective is to protect human health and the environment.Directive 2011/65/EU lists the following RoHS-regulated substances:LeadMercuryCadmiumHexavalent chromiumPBB – Polybrominated biphenyls … Read more
