Electronic pressure sensors usually measure the change in pressure through the deformation of a diaphragm. If this diaphragm is exposed to the process pressure on one side and "vented" on the other side (and thus exposed to the ambient pressure), the deformation is …
In most applications, gauge pressure measurement is required and therefore pressure sensors and pressure transmitters that measure pressure against the prevailing ambient pressure are commonly used for this. Those pressure sensors typically have a venting hole to …
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 …
