Overview
What is a Pressure Switch?
A pressure switch is an electronic or mechanical device that informs that a certain set pressure is reached. It is installed in systems where monitoring pressures are required. When a preset fluid pressure is reached, the pressure switch activates an electrical contact. A wide range of industrial and residential applications are found for pressure switches. Some typical applications where pressure switches are used are Furnaces, HVAC systems, Well pumps, etc. In this article, we will discuss the working, types, selection, and applications of pressure switches.
Pressure switches are devices that are used to monitor the pressure level of a process. The device informs a pressure rise or fall and thus helps in controlling systems of pressurized fluids. Based on the current pressure situation of the system the device becomes On or OFF. A range of process control systems uses pressure switches. The device usually consists of the below-mentioned components:
A pliable and sensitive diaphragm for detecting pressure.
A spring to adjust preset points or cut-out points.
A lever to activate or deactivate the pressure switch.
Electrical contact from an external power source.
Terminals for connecting the external power source to the contacts.
