When if you undertake a mechanical pressure switch so when should you rather choose for an electric pressure switch? Each switch principle offers advantages, but also has its limitations. Among other activities, there are differences in the application 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 are often used once the budget is bound and only individual switch points are needed. They are often found 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 aren’t the first choice in electronic systems, as they are often affected by mechanical wear, causing signal drift and even premature failure.
Most Important 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 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, an area indication by display or flexible adjustment and programming are essential, electronic pressure switches will be the primary choice.
