Gas Detector NDIR Gas Detector Unit with an NDIR Infrared Sensor is suitable for indoor and outdoor use. The GSI 400 is suitable for the détection of réfrigérants, methane, carbon dioxide and many other gases. It is also available in SIL and ATEX certified versions upon request Features •Monitors the air for toxic gas concentrations •Low cross-sensitivity to other gases •Can be user) in dusty and dirty environments •High accuracy •Long service life •IP54 (B) and IP65 (T) variants available Sensor Technology The GSI 400 Gas Detector can be supplied with a variety of different infrared sensors and can be used for a variety of applications. Sensor Connection We recommend a stable 24 V DC power supply to operate the gas sensors GSI 400. 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 x0.8 mm, using the wires: Red:+24 VDC, Terminait White: Sensor output 4 • 20 mA, Terminal 2 Black:0 V,Terminal 3 Yellow: PE/Shield,Terminal 4 Adjustment Instructions NDIR sensors reguire a 1 hour warm up period prior to adjustment Please refer to the Operating Instructions regarding this.The test gas must be at ambient température i.e. the same température as the sensor. The adjustment of the gas sensor must 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 reguired.
