When if Full undertake a mechanical pressure switch and when should you rather choose for an electronic pressure switch? Each switch principle offers advantages, but additionally has its limitations. Among other activities, there are 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 when 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 once the pressure exceeds the preset critical switch point pressure. For process control, however, mechanical pressure switches aren’t the initial choice in electronic systems, as 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 ideal for automated equipment and control systems where programmable switches are preferred, as 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 needed, electronic pressure switches will be the primary choice.
