When if you undertake a mechanical pressure switch so when should you rather decide for an electric pressure switch? Peril offers advantages, but additionally has its limitations. Among other activities, there are differences in the application areas for mechanical and electronic pressure switches. Considered of this will support you in your selection.
Application areas for mechanical pressure switches
Mechanical pressure switches tend to be used when 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 years, they transmit an instantaneous switching signal once 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 important. 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 time. Whenever additional analogue output signals, a local indication by display or flexible adjustment and programming are essential, electronic pressure switches will be the primary choice.
