Understanding Pressure Switch on separator Pressure switch Separator is a safety device that serves to prevent abnormal pressure from occurring in the Separator. Both excessive pressure (too high) and less pressure (too low) by closing the flow leading to Separator if Pressure Control fails to control pressure.

This Pressure Switch has two sensors, namely:

  1. Pressure Switch High,
  2. Pressure Switch Low.

If the set point in both Pressure Switches is reached, it will cause the shutdown system to work so that the Separator avoids danger, especially the danger of too high a pressure.

How High Pressure Switch works

The way the High Pressure Switch works is if the pressure reaches a set point that has been determined, then the pressure will push up the “switch” from the pressure so that the electric current is connected (closed) and will activate the alarm in the Control Room Panel. Shutdown System.

How Low Pressure Switch works

The way the Low Pressure Switch works is that when the pressure is too low and reaches the Low Pressure set point, the Pressure Switch “low” will work (become closed when the pressure drops). With reduced pressure causing a spring (spring) nothing will hold so that the switch moves down and an electric current is connected enabling an alarm and shutdown to occur.
