Description

The HYDAC EDS-3446-3-0250-000 is an electronic pressure switch designed for reliable pressure monitoring in hydraulic and pneumatic systems.

The device uses a thin-film strain gauge measurement cell on a stainless-steel membrane and incorporates a digital display for convenient pressure indication. According to HYDAC, the EDS 3400 series can provide programmable switching functions together with an optional analog output, making it suitable for machine control, pressure monitoring and system protection.

For the 908165 version, HYDAC specifies a 0–250 bar measuring range, one adjustable PNP switching output and an analog output selectable between 4–20 mA and 0–10 V.

The pressure switch can be configured for normally open or normally closed switching operation, with adjustable switch-on and switch-off delays. The display can also be configured to show actual pressure, peak value or switching-point information.
