GSE 400 GSE 400 Gas Detector electrochemical Gas Detector Unit with an electrochemical sensor is suitable for indoor and outdoor use. The GSE 400 is suitable for the detection of toxic or combustible gases as well as oxygen. GSE 400 offers the highest reliability and maximum performance in a compact housing. Factory calibration to industry standard measuring ranges. Suitable for all industrial areas. Sensor technology • Monitoring the air for toxic gas concentrations • Low cross-sensitivity to other gases • Can be used in dusty and dirty environments • High accuracy • IP54 (B) and IP65 (T) variants available The GSE 400 gas sensor can be equipped with many different electrochemical sensors, used for a variety of applications. A selection of standard gas types is listed below. Measuring ranges and Specification of the gas sensor should always be adapted to the application and ambient conditions. Sensor Connection We recommend a stable 24 V DC power supply to operate the gas sensors GSE 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 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 Safety 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. 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. 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 required. It is theretofore imperative that the section in the manual titled “Safety Instructions for Installers and Operators“ is read and strictly observed!

Technical Rules for Hazardous Substances - Occupational Exposure Limit Values TRGS 900 The current occupational exposure limit values (OELs) can be found in the Table contained within the Data Sheet. The limit values were defined by TRGS900 and may change. Please check the valid workplace limit values before defining the limit values. Gas sensors for all your requirements! The innovative design of the housing, makes installation simple and quick, as well as enabling their use indoors and outdoors. SCENTY® Gas Sensors are the first choice for safe monitoring technology.
