[Product Introduction – EDN.850 Differential Pressure Transmitter]

The EDN.850 Differential Pressure Transmitter is equipped with an LCD window featuring a white backlight for enhanced visibility. The housing is made of aluminum, and all wetted parts (the components in contact with the measured media) are constructed from stainless steel, ensuring excellent chemical resistance under most operating conditions except for certain special fluids.

Depending on specific industrial requirements, the pressure connection can be provided with an optional male adapter in addition to the standard female ports.

The welded joints are fabricated using a combination of laser welding and argon welding, ensuring high durability and reliability. The sensor utilizes a piezoresistive silicon pressure element. The pressure measurement range covers from 70 mbar up to 40 bar, with a static pressure (line pressure) rating of up to 200 bar.
