Differential Pressure Indicator Transmitter DE38 | Fischer

Key Features: Differential Pressure Indicator Transmitter Fischer DE38

The Fischer DE38 is a differential pressure transmitter and indicator with integrated digital display, engineered for accurate and rugged measurements in neutral gaseous and liquid media. It covers measuring ranges from 0…60 mbar to 0…25 bar (uni- or bidirectional), configurable analog output (4-20 mA / 0-10 V), and up to 2 potential-free switching contacts. Features an LCD display with backlighting and color change (green/yellow/red) for instant status visualization, plus intuitive on-device or software programming. Aluminum or stainless steel housing with IP65/IP67 protection, ideal for demanding industrial environments. As distributor at Garmasl, we emphasize its precision, multifunctionality, and seamless integration into control systems, positioning it as one of the best solutions in the market for differential pressure monitoring and transmission with local indication.
