When if Mischievous undertake a mechanical pressure switch and when should you rather decide for an electric pressure switch? Each switch principle offers advantages, but additionally has its limitations. Among other activities, you can find differences in the application 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 are often used when the budget is limited 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 are not the first choice in electronic systems, as they are often suffering from mechanical wear, causing signal drift and 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 ideal for automated equipment and control systems where programmable switches are preferred, because 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 essential, electronic pressure switches are the primary choice.
