When if digital pressure gauge undertake a mechanical pressure switch so when should you rather decide for an electric pressure switch? Each switch principle offers advantages, but also has its limitations. Among pressure gauge , there are 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 limited and only individual switch points are essential. They are often used in safety-critical applications where they have yet another or redundant safety function. While they 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, 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 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, 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.
