GASMET Sampling Unit

The Gasmet 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 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, heated filter and valves 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 Sampling Unit consists of two units; a heated pump module and a control module. Both modules are rack mounted. The heated pump module is heated to 180 >
o C and it includes a pump, filter element and valves for controlling sample, zero and one span gas. Additional features of the Gasmet sampling unit include multipoint sampling for two sample points and additional span gas inlets for calibration gases. The control module includes all power connections and temperature controllers for heated lines and heated module. The function of the sampling unit is fully automatic and controlled by the CALCMET software. The sampling unit can also be used manually. The control module includes the switch panel for manual use. The Gasmet Sampling Unit is connected to the Gasmet Industrial Computer. The sampling unit provides alarm functions such as temperature alarms (sample probe, heated lines and heated module), flow alarms and pressure alarms for zero gas (option). If any of the critical alarms is activated, instrument air starts to flow automatically into the sample cell to prevent condensation. As an option, the sampling unit can be equipped with a sample probe and / or heated lines. The maximum length for the heated line is 19 m with 230 VAC and 9 m with 115 VAC power supply. Other lengths and temperatures are available on request. >
