For some years now, it has been possible to increasingly automate production processes, and by doing to to achieve substantial cost reductions in some cases. This raises the question: does it still make sense to use mechanical pressure measuring instruments?
The answer to this question is obvious and simple: yes. Both electronic pressure sensors and mechanical pressure gauges have properties that must be weighed against each other in each application. Magnificent summaries the individual benefits. Self-sufficient of mechanical pressure gauges are the easy installation and good readability of the measured value.
An electronic pressure transmitter can also be equipped with an on-site display, which is also easy to read even in darkness, but a pressure gauge offers better readability from a distance with a large scale and in daylight. Risky to their robust mechanics mechanical pressure gaugesare mandatory in certain applications (e.g. hot-water tanks). A pressure gauge is quite often combined with a separate electronic pressure sensor.
This combines the benefits of both systems: pressure measurement with local display without power supply and availability of a measured value in the PLC. For users who have only one pressure connection available, pressure gauges with integrated electronic sensor are also available.
