GSC 200 Gas Detector electrochemical for Oxygen
3Pages

Gas Detector electrochemical for Oxygen Gas Detector Unit with an electrochemical sensor is suitable for indoor and outdoor use, and specifically designed for monitoring oxygen levels. Versatile and reliable with innovative modular design makes it suitable for all industrial sectors. Waterproof housing makes GSC 200 ideal for the food industry. Features • Continuous monitoring for oxygen depletion and enrichment concentrations • Low cross-sensitivity to other gases • Protected against dusty and dirty environments • High accuracy • IP54 (B) and IP65 (T) variants available Sensor Technology Our GSC 200 Gas Sensor is designed for the monitoring of oxygen depletion and enrichment to comply with occupational exposure limits (OELs). The electrochemical sensor offers long-term stability and has a low transverse sensitivity. It is suitable for use in harsh industrial environments - and with our especially developed waterproof housing, is ideal for use in food processing or wet environments. Sensor Connection We recommend a stable 24 V DC power supply to operate the gas sensors GSC 200. 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 2 x 2 x 0.8 mm, using the wires: Red: +24 V DC, Terminal 1 White: Sensor output 4 - 20 mA, Terminal 2 Black: 0 V, Terminal 3 Yellow: PE/Shield, Terminal 4 We recommend twisting the supplementary earth wire and the yellow wire at the control unit and connecting those two to sensor terminal 4 (PE). At the sensor end the supplementary wire is to be connected to the enclosure, making sure that the bare wire does not touch any of the electronic parts. If the sensor box is mounted on a steel structure connected to PE, the supplementary wire and terminal 5 should not be connected to the enclosure. Adjustment Instructions Electrochemical sensors require a 1 hour warm up period prior to adjustment. Please refer to the Operating Instructions regarding this. The test gas must be at ambient temperature i.e. the same temperature as the sensor. The adjustment of the gas sensor may only be carried out by suitably qualified persons. In order to adjust and calibrate any SCENTY® Gas Warning System and Gas Sensors, the corresponding Software modules are required. Rev.II_102019_GSC 200_engL • Subject to alterations Safety Instructions Careful handling of the gas sensors and their use in areas where monitoring is required needs specialist knowledge and procedures, which can be found in the relevant Instruction Manual. It is theretofore imperative that the section in the manual titled “Safety Instructions for Installers and Operators“ is read and strictly observed! We control GASES - since 1978 HAMBURG
