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

(example: If the Pressure switch with output impedance of 1k is connected to the A/D converter to detect the analog output of 5V, the detected voltage by the A/D converter becomes 5(V) x 1(M)/(1(k) + 1(M)) 4.995(V), and there is an error of approximate 0.005 V). Output impedance The operation principle of the switch output. Normal output and reverse output can be selected.
