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 also has its limitations. Among other things, there are differences in the application 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 are often used when the budget is bound and only individual switch points are essential. They are often used in safety-critical applications in which they have an additional or redundant safety function. While they remain idle for some 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 initial choice in electronic systems, because they are often affected by mechanical wear, causing signal drift and even premature failure.
Contrary 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, as the desired setting for the switch point may change over the years. Whenever additional analogue output signals, an area indication by display or flexible adjustment and programming are needed, electronic pressure switches are the primary choice.
