Proportional regulators, also known as I to P or E to P valves, provide an easy and reliable way to convert a control signal to a pressure. They are essential in applications where precise pneumatic control is critical. While some proportional regulators are used straight out of the box with no configuration, others require tuning to perform in specific ways. This tuning process can seem daunting, leading to the reputation that these regulators are “more art than science.” However, for customers looking to customize the response of a product, field-tunable regulators are necessary. In this blog post, we’ll explore the benefits of tuning proportional regulators and how DAS software streamlines the tuning process for the Sentronic series of regulators.
