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 …
If pressure sensors, pressure transmitters and other field equipment are used in the vicinity of flammable gases or dust, they may be subject to marking in accordance with the ATEX product guideline 94/9/EC. ATEX requires the type label of the sensor to include the …
When using pressure sensors, the output signals 0 … 20 mA, 4 … 20 mA and DC 0 … 10 V are frequently chosen in order for the sensor signals to be evaluated and further processed. For this, the signal output of the pressure sensor is usually connected to a …
As WIKA representative, I have made a contribution to the preparation of the “VDMA Specification Sheet for Fluid Sensors 24574-1 Part 1 Pressure Switches”. What were the objectives of this VDMA committee? Very simple: The objective of the VDMA specification is to …
In so-called “gauge sensors” pressure is always measured relative to the currently prevailing ambient pressure. However, the ambient pressure is by no means constant. It is location- and height-dependent and changes with the weather. This means that for a …
