Gas detector GSZ 300

oxygenoutdoorfor indoor use

Gas Detector zirconium oxide Gas detector with zirconium oxide sensor, for indoor and outdoor use, designed for monitoring oxygen levels. Fast response time, long service life and minimal calibration requirments make the GSZ 500 an idéal reliable gas sensor in ail industrial sectors. Features •Continuous monitoring for oxygen déplétion and enrichment concentrations •Lowcross-sensitivityto other gases •Protected against dusty and dirty environments Sensor Technology Gas Sensor GSZ 300 is designed for the monitoring of oxygen déplétion and enrichment comply with occupational exposure limits (AGW). The zirconium oxide sensor has a long service life of at least 5 years, long-term stability and has a low cross sensitivity to other gases. It is suitable for use in harsh industrial environments - and with our especially developed waterproof housing, is idéal for use in food Processing or wet areas. Sensor Connection We recommend a stable 24 V DC power supply to operate the gas sensors GSZ 300. The allowed voltage range is 18 to 36 V DC.The sensor may be connected using a shielded cable with two twisted pairs, i.e.JY(St)Y 2x2 x 0.8 mm, using the wires: Red:+24 VDC, Terminal 1 White: Sensor output 4 • 20 mA, Terminal 2 Black: 0 V, Terminal 3 Yellow: PE/Shield, Terminal 4 •High accuracy •Long service Life •IP54 (B) and IP65 (T) variants available Further fields of application: •Air Ouality Monitorîng •Food Industry •Greenhouses •Fruit and Vegetable Storage •Biogas Facilities •Medical Equipment •Laboratory Instruments We recommend twisting the supplementary earth wire and the yellow wire at the control unit and connecting those two to sensor terminal 4 (PE).
