Today you will find that pressure sensing devices are used in many industries where high pressure is imposed for production purposes. One of the most popular of these devices is the pressure switch. The main role of these switches is to switch off an application when the pressure level surpasses a setpoint limit. With the help of these devices, you can monitor pressure levels and hence prevent accidents.
Due to different requirements, different types of pressures are now available. Out of these options, differential pressure switches are commonly used.
How do differential pressure switches work?
Compared to other types of pressure gauging switches, differential pressure switches can easily check the pressure between two different pressure setpoints at the same time. These switches are used in applications such as fuel cells and refrigeration devices.
What to consider before buying pressure switches
If you are purchasing pressure switches then you have to consider some factors. Firstly, you have to check the setpoint of the pressure system. You also have to keep the price, response time and durability of the switches in mind. It is a good idea to get a switch which allows you to change its setpoint value according to your specific needs.
