1. General Description

 

The HYDAC HDA 4445-A-250-000 is a robust, electronic pressure transmitter designed for high-pressure hydraulic applications. It features a stainless steel measuring cell with a thin-film strain gauge on a stainless steel membrane, ensuring excellent long-term stability and accuracy.

This model provides an analog output (4-20 mA) proportional to the system pressure. Its compact design, high shock and vibration resistance, and IP65 protection make it ideal for use in demanding mobile and industrial hydraulic systems, such as presses, plastic injection molding machines, and mobile hydraulics.

Key Features 🎯

 

• High-Pressure Capability: Measuring range up to 250 bar.

• Robust Construction: Stainless steel sensor cell for high durability.

• Analog Output: Standard 4-20 mA (2-wire) signal for reliable transmission over long distances.

• High Accuracy: Typically $\le$ ± 0.5 % BFSL accuracy.

• Standard Connection: DIN 43650 (Valve Plug) style electrical connection (Code -A-).

• EMC Protection: Excellent electromagnetic compatibility for industrial environments.
