Pressure sensor controllers are electronic devices that are used alongside pressure sensors to affect the pressure levels of liquid or gas in a given system. They also allow the pressure sensors to be controlled remotely, which is very useful as it means a user can control a number of sensors from one place, rather than having to adjust each sensor individually.
Pressure sensor controllers are connected to one or more pressure sensors and display the pressure range on a digital screen. If the pressure level is not satisfactory, the user can adjust it using the buttons on the controller.
Pressure sensor controllers differ in their supply current and voltage, IP rating and importantly by the number of switching outputs they offer. The type and function of a controller may be determined by the number of pressure sensors you need to control at one time. They come in varying sizes.
