DESCRIPTION

Pressure transducers and pressure switches are often confused as similar devices, however, they are functionally different. While both are used in pressure measurement applications, pressure transducers provide a continuous output, typically connected to a controller, which monitors and performs actions based upon the pressure within the system. A pressure switch is a simpler device that does not provide a continuous output. Instead, it’s an on/off device functionally similar to a light switch. A pressure switch is set up to open or close a circuit based upon the pressure in a system rising or falling to a preset threshold.
