Are mechanical pressure gauges still useful?

Yes. Both mechanical and electronic pressure gauges have characteristics that need to be weighed for a process. The main points of the mechanical devices are the ease of installation and very good readability at a distance with a large scale. Because of this, mechanical pressure gauges are even required by law in some applications. The advantage of the electronic pressure sensor is that you can attach a display that allows you to read readings in the dark.

Manometers with a separate electronic pressure sensor are also often installed. In addition, for easy reading of the measured values, they can also be made available in the PLC.
