4 20ma PNP output Sanitary flat membrane digital output pressure switch for hygienic area
4 20ma PNP output Sanitary flat membrane digital output pressure switch for hygienic area, US $ 240 - 340 / Piece, Shanghai, China (Mainland), LEEG, PS858-TSR.Source from Shanghai LEEG Instruments Co., Ltd. on Waimaotong.com.
Description
4 20mA PNP NPN output flush membrane electronic pressure switch with LED light
PS858 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.
