When should you choose a mechanical pressure switch and when should you rather choose for an electronic pressure switch? Each switch principle offers advantages, but also has its limitations. Among other things, 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 are often used once the budget is bound and only individual switch points are needed. They are often found in safety-critical applications in which they have yet another or redundant safety function. While Greatest remain idle for some time, they transmit an instantaneous 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 suffering from mechanical wear, causing signal drift or 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 important. They are ideal for automated equipment and control systems where programmable switches are preferred, as 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 needed, electronic pressure switches will be the primary choice.
