When using pressure sensors in safety-relevant applications, sooner or later one must ask the question whether the SIL evaluation of the proposed pressure sensor is sufficient for the application. Often, the user tends to favour pressure sensors with higher SIL …

Selection criteria for the prevention of moisture-related failures of submersible pressure transmitters or level probes
Enrico Bossart | Know-howSubmersible pressure transmitters as well known as level probes are intended to be used in immersion applications, thus they are immersed completely into the medium and, therefore, must withstand the properties of the media at all times. Both in water and …
What is volume weight?
Michèle Beyer | Know-howOr why it is important to find the right packaging for each product. Next to the actual weight which can be determined by weighing, there is also a so-called "volume weight". This is used for calculating transport costs. In addition to the actual weight, the …
Analogue output signals from pressure sensors 3: 0.5 … 4.5 V ratiometric
Stefan Heusel | Know-howFor some applications, for example in vehicles or battery operated applications, an output signal is required which can be operated at low power to enable a long service life. Normally, ratiometric signals are transmitted as 10 ... 90 % of the powersupply voltage. …
How to select an isolated barrier for an intrinsically safe pressure sensor
Stefan Heusel | Know-howIn 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 …
