The ZSE20B(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 ZSE20B(F) adds a 2nd switch output, as well as an analog output, either voltage or current. The ZSE20B(F) also has an IP65 protection rating, compared to the ZSE20A's IP40. ZSE20B is vacuum rated, while the ZSE20BF is rated for both vacuum and a low positive pressure range. Each model in the ZSE20 family offers a 3-screen, 3-color display. The main screen shows the curent measured value in red or green, while two sub-screens can display the setting label and its numeric value in orange. Delay time for the switch output can be as brief as 1.5 ms, while current consumption is held to 35 mA or less. ZSE20B(F) is UL/CSA, CE and RoHS compliant, with an IP65 enclosure rating.
