This document is the technical data sheet of the COMBI MASS® series, which introduces the characteristics of the products in this series, including application range, working temperature, sensor technology, etc.
The COMBIMASS eco series consists of field transmitters suitable for gas flow measurement using thermal dispersion technology. These instruments are designed for process temperatures up to 220°C and are available in explosion-proof versions. The electronics feature high-performance digital signal processing with temperature compensation and selectable measuring modes.
The system offers various signal outputs, including isolated 4-20 mA analog and pulse outputs, with optional field displays and graphic displays. It is compatible with a wide range of sensors and can be used for applications involving compressed air, technical gases, combustion gases, and process gases.
