S43.55A

The S43.55A is an industrial pressure switch designed to measure and control the pressure of a system for a variety of applications. It is a high-end, all-purpose pressure switch capable of providing accurate readings to help ensure consistent operation of industrial processes.

The S43.55A is suitable for use in processes that require the greatest accuracy such as pressure control in flight or process systems. It is constructed from stainless-steel, brass, and bronze components with an operating range of -500 to 5500kPa. The S43.55A can be used in applications such as hydraulic systems, compressors, air suspension, and air/gas conditioning systems.

Working Principle

The S43.55A pressure switch utilizes an electrical pull switch and a mechanically operated set point spring. When the pressure rises in the system, the potential difference across the bellows of the pull switch causes it to actuate and opens the internal contact. This triggers the connected electrical switch to open, thus inhibiting the system pressure from rising any higher. When the pressure drops, the bellows switch returns to its original position and the contact closes again.

A set point spring is also incorporated into the working mechanism of the pressure switch. This spring is adjustable via a setting screw on the top of the switch and can be used to customize the action point of the switch\'s electrical contact. Adjusting the screw allows the user to set up the switch to activate or deactivate the system pressure at a desired level.

Conclusion

The S43.55A is a high-end and highly accurate industrial pressure switch suitable for a range of applications. Its simple and robust design makes it easy to use and adjust while its wide operating range allows for greater flexibility in use. Its ability to measure or control pressure in extremely sensitive processes makes it a popular choice for many applications.
