Key Features: Differential Pressure Transmitter Indicator Fischer DE39

The Fischer DE39 is a multifunctional digital differential pressure transmitter with 4-digit LCD display and color change (green/yellow/red), engineered for accurate measurement and transmission of differential pressure, overpressure, and partial vacuum in neutral gaseous and liquid media. Covers ranges from **0…0.6 bar to 0…40 bar** (per model), with configurable analog output 4-20 mA or 0-10 V, 24 V DC/AC supply, and backlit display that changes color for instant visual alarm indication. Process connection via cutting ring fitting for 6-8 mm tubes, rugged housing with IP65/IP67 protection. Selectable operating modes (differential, 2-channel relative pressure, or absolute pressure) and simple programming. As distributor at Garmasl, we highlight its 2.5% accuracy, intuitive visual alarm, and industrial versatility, positioning it as one of the best solutions in the market for differential pressure monitoring and transmission with advanced local indication and zero maintenance.
