We all know the roles of mechanical pressure gauges and switches. They either give us a visual indication of hydraulic pressure, or open or close a switch when reaching a certain threshold pressure. Electronic pressure transducers do the same, but more effectively and with a single component instead of two or three. Furthermore, an electronic pressure transducer provides more output variations, longer life, and greater accuracy.
Mechanical pressure gauges and switches still have their place in fluid power, but with more features and greater accuracy and life, transducers are being specified in a wide variety of applications. In an article recently published in Hydraulics and Pneumatics these applications and their conditions are discussed in greater detail. You can read the entire article on the Hydraulics and Pneumatics website.
