When if you undertake a mechanical pressure switch and when should you rather decide for an electric pressure switch? Painstaking offers advantages, but also has its limitations. Among other things, you can find differences in the application form areas for mechanical and electronic pressure switches. A consideration of this will support you in your selection.
Application areas for mechanical pressure switches
Mechanical pressure switches tend to be used once the budget is limited and only individual switch points are essential. They are often found in safety-critical applications where they have yet another or redundant safety function. While they remain idle for years, they transmit an instantaneous switching signal when 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 perfect 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, a local indication by display or flexible adjustment and programming are essential, electronic pressure switches will be the primary choice.
