Suction System AS-1 Biogas Article-No.: 410103 Features Transmitter Control Unit Sampling of Gas Distance for Suction Conditioning of Measured Gas Operation Temperature Mechanical Features Dimensions Housing Material Storage Temperature Electrical Features Power Supplies Cable Gland Terminal Assignment Suction System for one measuring point: sampling of measured gas and transmitter combined in one wall mounted housing. Continuous sampling and measurement. Including flame arrestor and automatic condensate trap incl. peristaltic pump. (Particularly suitable for biogas application, e. g. CH4-, CO2- and O2-measurement; not for H2S) ■ Number: 1 (not included in scope of delivery) ■ Freely selectable Externally, e. g. by ExTox Control Unit ■ Gas suction pump ■ Electrical flow monitoring by means of pressure difference measurement: in case of under-scale of the minimum flow fault message is issued by disrupting the transmitter output signal (4...20 mA) ■ 2 screw-in connections (4/6 mm) for inlet and outlet of meas ured gas at the bottom of the housing ■ 1 screw-in connections (4/6 mm) for outlet of condensate at the bottom of the housing > 50 m when using hose 4/6 mm(inner/outer 0: 4/6 mm) ■ Hosing: PE/PP ■ Condensate trap incl. peristaltic pump 300 ml/h ■ Flame Arrestor © IIG IIB3 in the gas inlet -10 °C to +40 °C (Limitations due to used transmitters have to be considered) 500 mm x 500 mm x 300 mm (Height x Width x Depth) Wall mounted housing with door, mounting plate, foamed-in door sealing, 1 cam lock Steel, powder-coated in textured RAL 7035 -25 °C to +60 °C (Limitations due to used transmitters have to be considered) ■ External: 230 V AC (Pump) ■ From control unit: 24 V DC (Transmitter) At the bottom of the housing ■ 1 x M20 x 1.5 (diameter of cable 7-13 mm) Double stock clamps for ■ Power Supply (230 VAC fused with 6 A) ■ Transmitter (+ 24 VDC, GND, 4.20 mA) ExTox Gasmess-Systeme GmbH • Max-Planck-StraGe 15 a • 59423 Unna (Germany) • Tel. +49 2303 33 247-0 • Fax +49 2303 33 247-10 Internet: www.extox.de • mail to: [email protected] 410103_AS-1-Biogas_e_2014-06-04.docx,05/06

Suction System AS-1 Biogas Article-No.: 410103 Connection Scheme Options ■ ExTox-Transmitter: Depending on type of measured component a suitable transmitter can be chosen out of the ExTox programme. As far as incompatibilities of some gases with hosing materials are concerned ExTox will be at your disposal in case you require any advice. ■ ExTox-Control Unit: The measuring signal supplied by the Suction System AS-1 can be evaluated by every ExTox-Control Unit. ■ Flame Arrestor <© IIG IIB3 (Art.-No. 940250) or © IIG IIC, e. g. for hydrogen (Art.-No. 940251): When sampling in hazardous areas the...
