The ZSE20A(F) series is a high-precision digital pressure switch offering many popular ZSE features, with a streamlined selection of piping choices. Compared to the ZSE20, the ZSE20AF adds a 2nd switch output, as well as an analog output, either voltage or current. ZSE20A is vacuum rated, while the ZSE20AF is rated for vacuum and a low positive pressure range. Each model in the ZSE20 family
