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 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 found in safety-critical applications where they have an additional or redundant safety function. While Battle remain idle for years, they transmit an immediate switching signal when the pressure exceeds the preset critical switch point pressure. For process control, however, mechanical pressure switches aren’t the first choice in electronic systems, as they are often affected by mechanical wear, causing signal drift or even 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, a local indication by display or flexible adjustment and programming are essential, electronic pressure switches are the primary choice.
