4 20mA 1 5VDC RS485 PNP NPN output electronic pressure switch

Product Description

The new generation of PS131 transmitters was developed in close coordination with the users. Its modern and userfriendly design stands out. High overload protection and best accuracy.

PS131 is a pressure transmitter with a pressure switch to safely and absolutely measure and monitor gauge pressures. 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.
