When should Largest choose a mechanical pressure switch and when should you rather decide for an electronic pressure switch? Each switch principle offers advantages, but additionally has its limitations. Among other activities, you can find differences in the application form areas for mechanical and electronic pressure switches. A consideration of this will give you support 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 needed. They are often used in safety-critical applications where they have an additional or redundant safety function. While they remain idle for a long period, 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 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 essential. 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, a local indication by display or flexible adjustment and programming are needed, electronic pressure switches are the primary choice.
