When should you 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. Considered of Noted 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 used in safety-critical applications where they have an additional or redundant safety function. While they remain idle for years, 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, 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 important. They are ideal 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, an area indication by display or flexible adjustment and programming are essential, electronic pressure switches are the primary choice.
