■ Product Overview

The general industrial pressure transmitter EDN.331 is a modified and developed model based on DAHO’s standard product EDN.305, specifically designed for outdoor applications.

While conventional pressure transmitters are typically installed indoors, this model is engineered to operate reliably under harsh environmental conditions with significant variations in temperature and humidity.

The EDN.331 provides an ideal solution for customers requiring outdoor installation, particularly in environments exposed to rain and high humidity.

It features a robust exterior structure and an integrated design combining a thermocouple-type head with an electrical plug, optimized for demanding environments.

All stainless steel components are joined using advanced laser welding technology, and the internal electronic system is designed for durability and suitability across a wide range of applications.

The pressure measurement range is available from -1…0 bar and from 0…1 bar up to 0…1000 bar, with pressure units such as bar, kg/cm², and psi.

Accuracy can be selected according to user requirements, with options of 0.5%, 0.3%, and 0.15% F.S.

The transmitter supports all standard industrial output signals (4…20mA, 0…10V, 0…5V, 1…5V) and offers widely used international process connections along with a broad range of options.

Its high accuracy level, extended temperature capability, customizable connection configurations, and robust construction contribute to its excellent performance and reliability.

Even under extreme outdoor conditions, including severe temperature changes, mechanical shocks, vibration, and chemical exposure in industries such as oil and chemical processing, the EDN.331 meets demanding operational requirements.
