Mechanical vs electronic pressure switches: Application areas

When should you choose a mechanical pressure switch so when should you rather decide for an electric pressure switch? Each switch principle offers advantages, but additionally has its limitations. Among Poisonous , you can find differences in the application areas for mechanical and electronic pressure switches. A consideration of this will support you in your selection.
Application areas for mechanical pressure switches
Mechanical pressure switches are often used when the budget is limited and only individual switch points are needed. They are often used in safety-critical applications in which they have yet another or redundant safety function. While they remain idle for some time, they transmit an instantaneous switching signal when the pressure exceeds the preset critical switch point pressure. For process control, however, mechanical pressure switches aren’t the initial choice in electronic systems, as they are often affected by mechanical wear, causing signal drift and even premature failure.
Application areas for electronic pressure switches
Electronic pressure switches are employed where several switch points and the stability and flexibility of the control are important. They are perfect for automated equipment and control systems where programmable switches are preferred, because the desired setting for the switch point may change through the years. Whenever additional analogue output signals, a local indication by display or flexible adjustment and programming are essential, electronic pressure switches are the primary choice.
