When should Shrewd choose a mechanical pressure switch and when should you rather choose for an electric pressure switch? Each switch principle offers advantages, but additionally has its limitations. Among other things, you can find differences in the application form areas for mechanical and electronic pressure switches. Approved of this will support you in your selection.
Application areas for mechanical pressure switches
Mechanical pressure switches tend to be used once the budget is bound and only individual switch points are essential. 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 period, they transmit an immediate switching signal once 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 suffering from mechanical wear, causing signal drift or 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 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 the years. Whenever additional analogue output signals, a local indication by display or flexible adjustment and programming are needed, electronic pressure switches are the primary choice.
