Your transmitter needs power to work. Your SOR Measurement and Control mechanical pressure switch does not.

When a facility loses power, most instrumentation goes offline. A mechanical pressure switch keeps monitoring. It triggers hardwired alarms and shutdowns using process pressure alone.

🔴 No external power required.
🔴 No communication link required.
🔴 No electrical system dependency.

Engineers specify mechanical pressure switches alongside transmitters in critical applications for exactly this reason.

⚙️ One switch. Zero dependency on your power grid.
