■ Product Overview

The EDN.850 differential pressure transmitter is equipped with an LCD window featuring a white backlight. The housing is made of aluminum, and all wetted parts are constructed from stainless steel.

Except for special fluids, chemical corrosion does not occur, and depending on industrial requirements, a male adapter can be added to the female pressure connection.

The welded joints are fabricated using both laser welding and argon welding, ensuring high reliability and durability.

The pressure sensor utilizes a piezoresistive silicon element, with a measurement range from 70 mbar up to 40 bar, and a maximum static (line) pressure of 200 bar.
