What is a pressure switch, and how does it work with a pump?
A pressure switch is a device that monitors the pressure within a system and automatically controls the operation of a pump based on that pressure. It consists of a pressure sensor, an actuator, and electrical contacts that open or close to start or stop the pump. By setting a specific pressure threshold, the switch can ensure that the pump operates only when necessary, helping to maintain optimal pressure in the system.
When the pressure drops below a specified point, the switch sends a signal to activate the pump, allowing it to increase the pressure accordingly. Conversely, when the desired pressure is reached, the switch will turn the pump off. This action not only conserves energy but also protects the pump from running dry, thus extending its lifespan.
What types of pressure switches are available for pumps?
There are several types of pressure switches used with pumps, including mechanical, electronic, and smart pressure switches.
