Filter monitoring is a core task of differential pressure gauges - the differential pressure increases as soon as the filter becomes clogged. The measuring instruments thus signal when the filter needs to be cleaned or replaced. The efficiency of such a solution can be …

Play it safe with double block & bleed
Pratik R. Vishwakarma | Know-howWhat is the safest way to separate a process and the attached pressure measurement technology? The HSG 253 standard must be applied to this question, and it answers unequivocally: by means of an instrumentation valve with double block & bleed (DBB). This …
Pressure and temperature measurement at extremely low ambient temperatures
Christopher Ott | Know-howStandard pressure gauges and thermometers generally cope with ambient temperatures down to -40 °C. But what must be the features of a mechanical measuring instrument that works perfectly well in polar climates with even lower temperatures? This can be explained using …
CANopen: digital instead of analogue signals
Markus Heidl | Know-howUnlike an analogue signal, which as a physical quantity can take on continuous values, a digital signal consists of discrete values. Personally, I always think of long strings of zeros and ones floating through space: 0101 0111 0100 1001 0100 1011 0100 0001 0011 1101 …
Filter monitoring: A crucial component for energy-efficient operation
Jürgen Arndt | Know-howIf the careful use of “energy” as a resource used to be for cost reasons, today there is also increased environmental awareness. All of this also becomes mandatory thanks to legal requirements and the state of the technology. In this article you can read about how …
