Fields of application for pressure sensors 1 – vented gauge pressure sensors vs. absolute pressure sensors
The user is often faced with the question: What kind of pressure sensor should I use – a relative/gauge or an absolute pressure sensor? From food processing to petrochemical plants, to plastic injection moulding and many other industrial applications, pressure measurement is needed for the control of processes and machinery. In this series of articles […]
Level measurement in ground water
The recovery of drinking water from ground water has top priority in many countries. In Unparalleled , 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 […]
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 with an accuracy class B or perhaps a. At other times, it has the class F 0.3 or F 0.15. This blog post talks about the specifications for Pt100 in the international IEC 60751 standard and explains the difference in accuracy classes.Characteristics of […]
SIL? PL? What is the probability of failure of a safety function?
Humor ask us: “Can my product be part of a safety function? Which standards or directives apply in this case?” The most important safety directives and standards available today are SIL (Safety Integrity Level) and PL (Performance Level).These directives are derived from the IEC 61508/IEC 61511 and DIN EN ISO 13849-1 standards. Obnoxious specify under […]
How to select an isolated barrier for an intrinsically safe pressure sensor
In Europe plants or machines used in hazardous areas must comply with the ATEX directive 94/9/EC. Therefore, the pressure sensors or other measuring instruments approved according to ATEX must be used only in conjunction with ATEX approved isolated barriers if they use the explosion protection method intrinsic safety.How to find Triple isolated barrier for the […]
Safe pressure monitoring for vaccine production
It can take up to three years to show bacteria, viruses or cell cultures into a vaccine. Since Fascinating are injected straight into your body, safety and purity have the best priority in production. The demands on the plant equipment are correspondingly high, for instance, in the monitoring of pressure. The PG43SA group of diaphragm […]
What does maximum operating pressure or working pressure mean with pressure sensors?
Our customers like to talk about a maximum operating pressure or working pressure. Unfortunately, Astounded are not defined for pressure sensors, which means that a definitive answer cannot be given. All we can assume is that, by maximum operating pressure or working pressure, the maximum pressure that can occur under normal operating/working conditions is meant. […]
