Silicon pressure transducer DMU 04

4-20 mA2-wireG 1/2

DMU 04 CP/MR for hygienic processes Small temperature error Options: Ex, field housing or high temperature version (up to 300 °C) and SIL 2 Application For applications requiring hygienic process connections, materials or processing, especially food technology, pharmaceutical and biotechnology applications. Description Pressure transducers convert physical pressure into an electrical signal proportional to the pressure. DMU 4 is equipped with an oil-filled piezo-resistive silicon measuring cell. DMU 04 has safety integrity level SIL 2 (IEC 61508/61511).
