The new generation of PS858 sensors was developed in close coordination with the users. Its modern and userfriendly design stands out. High overload protection and best accuracy. PS858 is a pressure sensor with a pressure switch to safely and absolutely measure and monitor gauge pressure. It is highly stable and has a function check and onsite information due to its OLED and digital display. It can be rotated up to 350° if placed on the upper part of the house, also the display contents can be rotated up and down.With flush diaphragm design, it can also be used for flush installation provided with an adapter and hygienic processes as well.
