Description
The analyzer consists of an explosion-proof dew point transducer (1Ex d IIA T5 Gb) and a secondary unit. There are two designs for the secondary unit: a central control unit (CCU) for installation in a 19-inch instrument rack and an interface unit (IU) for attachment to a vertical panel. The IU/CCU provides registration and storage of measurement data, conversion of measured dew point values to moisture content (g/m³), and converts natural gas water dew point values from the measured pressure to the contract pressure. By connecting the IU/CCU to an external computer it is possible to monitor on-line dew point measurements in order to evaluate measurement reliability.
The transducer can be mounted directly onto a gas pipeline (submersible configuration) or connected to the pipeline through a gas preparation system with a filtration option for the removal of mechanical and aerosol contaminants.

Signature features
- Automatic diagnostics of the cooling mirror
The analyzer’s operational algorithm includes automatic diagnostics of the cooling mirror surface and automatic cleaning of the mirror before each measurement cycle. - Increased difference between body temperature and the minimum mirror surface temperature.
The next-generation sensors integrated into the instrument’s innovative design make it possible to achieve temperature depression of 70 °C between the analyzer’s body temperature and the minimum temperature of the mirror’s surface at an operating pressure of 10 MPa. This is the best result among all known automatic chilled-mirror on-line hygrometers.
