The measurement system Hygrophil HCDT measures the hydrocarbon dew point and the moisture in natural gas, it monitors the quality of the gasand at the same time reliably protects the plant. The system consistsof the display unit Hygrophil F 5673, the moisture sensor L1660 and the HCDT sensor. Both are installed in a specially developed sample system and enable the precise, drift-free and fast detection of the hydrocarbon and water dew point. The chilled mirror method is an approved and precise standard technique to detect the dew point. The precision of the HCDT sensor is +/- 0,5°C. A measured value drift can be excludedas platinum temperature sensors are considered to be drift-free and neither movable nor easily wearing out sensor components have been integrated eliminating cyclical recalibration. The particles carried alongin the gas have no influence on the measurement. The condensation range for hydrocarbons is only 2x1mm, so that heating and cooling processes at the Peltier element can be carried out very quickly.
