When should you choose a mechanical pressure switch and when should you rather decide for an electronic 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 support you in your selection.
Application areas for mechanical pressure switches
Mechanical pressure switches are often used once the budget is bound and only individual switch points are needed. They are often found in safety-critical applications in which they have an additional or redundant safety function. While they remain idle for a long time, they transmit an immediate switching signal when the pressure exceeds the preset critical switch point pressure. For process control, however, mechanical pressure switches are not the first choice in electronic systems, because 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 employed where several switch points and the stability and flexibility of the control are essential. They are perfect for automated equipment and control systems where programmable switches are preferred, as the desired setting for the switch point may change over time. Whenever additional analogue output signals, a local indication by display or flexible adjustment and programming are essential, electronic pressure switches are the primary choice.
