When should you choose a mechanical pressure switch and when should you rather decide for an electronic pressure switch? Valor 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. A consideration 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 bound 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 a long time, 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, because they are often affected by mechanical wear, causing signal drift or even premature failure.
Application areas for electronic pressure switches
Electronic pressure switches are employed where several switch points and the stability and flexibility of the control are important. 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 time. Whenever additional analogue output signals, an area indication by display or flexible adjustment and programming are needed, electronic pressure switches will be the primary choice.
