When if เพรสเชอร์เกจ undertake a mechanical pressure switch so when should you rather decide for an electric pressure switch? Each switch principle offers advantages, but additionally has its limitations. Among other activities, 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 are often used once the budget is limited and only individual switch points are essential. They are often used in safety-critical applications in which they have an additional or redundant safety function. While they remain idle for a long period, they transmit an immediate switching signal when 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 affected by mechanical wear, causing signal drift as well as 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. digital pressure gauge are ideal 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.
