Mechanical vs electronic pressure switches: Application areas

When if you undertake a mechanical pressure switch and when should you rather decide for an electric pressure switch? Each switch principle offers advantages, but also has its limitations. Among other things, you can find differences in the application form areas for mechanical and electronic pressure switches. Considered of this will give you support in your selection.
Application areas for mechanical pressure switches
Mechanical pressure switches are often used once the budget is limited and only individual switch points are essential. They are often found in safety-critical applications where they have yet another or redundant safety function. While they remain idle for a long time, they transmit an immediate switching signal once the pressure exceeds the preset critical switch point pressure. For process control, however, mechanical pressure switches aren’t the first choice in electronic systems, as they are often affected by mechanical wear, causing signal drift as well as premature failure.
Application areas for electronic pressure switches
Electronic pressure switches are used 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, as 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 will be the primary choice.
