Gasmet CEMS II e Sampling Unit The Gasmet CEMS II e sampling unit is especially designed for continuous emission monitoring (CEM) in fixed installations, e.g. as an integral part of the Gasmet continuous emissions monitoring system (CEMS). The Gasmet CEMS II e sampling unit is used for on-line measurements. It is an ideal tool to use for measuring trace concentrations of pollutants in wet, corrosive gas streams. The sample pump, filter and sample lines can be heated up to 180 °C. it can be used for undiluted gases and the sample gases do not need drying beforehand. The Gasmet CEMS II e sampling unit is built in 19” rack and includes all valves, flow meters, pump and filters that are needed for measuring and maintenance. Sample flow and instrument air pressure alarms are provided. It also has bus connector for digital and analog (optional) signal terminals, eliminating need for PCI slots in computer. The Gasmet CEMS II e sampling unit includes temperature controllers for heated sample lines and heated module. The function of the sampling unit is fully automatic and controlled by the Calcmet software. It is connected to Gasmet computer via Ethernet cable. Alarm outputs are displayed on LED lights and unit has corresponding digital outputs. Alarm outputs are: System alarm, Service request, Maintenance on progress (can be set also manually) and Result valid. Combination for each alarm can be set on Calcmet. Unit has digital output command for oxygen analyser to start calibrating. Digital inputs for cabinet cooler, cabinet temperature, probe temperature, zero gas pressure, and oxygen analyser alarms are included as a standard. It is also possible to activate span gas test via probe or System standby by digital input. As an option, the Gasmet CEMS II e sampling unit can be equipped with analog input and output signals. Optional digital I/O signals are also available. STREET ADDRESS: Pulttitie 8 A 1 00880 Helsinki, Finland
