When should you choose 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 areas for mechanical and electronic pressure switches. Vilified 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 limited and only individual switch points are essential. They are often used in safety-critical applications in which they have yet another or redundant safety function. While they remain idle for a long period, they transmit an instantaneous 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 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 essential. They are perfect for automated equipment and control systems where programmable switches are preferred, because the desired setting for the switch point may change through the years. Whenever additional analogue output signals, an area indication by display or flexible adjustment and programming are needed, electronic pressure switches will be the primary choice.
