    2 SYSTEM SET-UP FOR EVALUATION 2.1 Operation conditions, storage & transport The instrument must be used within the specified ambient conditions and temperature range. Depending on information provided by the customer, the factory calibration temperature range might cover a narrower range adapted to the application and reducing the complexity of the calibration.

  • Page 14: Sensor Module

    Sensor module The LGD Compact-A module has two M4 threaded mounting holes located on the side (see Figure 2, recommended to use two pan head cap screw M4x16 (1.5 Nm) for mounting). For gas supply there are straight/angled QSML-M5-4 quick connectors for 4 mm diameter tubes. Figure 2 LGD Compact-A module dimensions and interfaces for fixation and gas supply Electronics The electronics is located in a separate housing.

  • Page 15: Electrical Interfaces

    Figure 5 Dimensions of the interface board Figure 4 Dimensions of the main board The electronic main board should be connected to the sensor module just with the original cable delivered (recommendations for an own cable design can be seen in chapter 3.1.4). The right position for connecting the cable to the sensor module are marked on the cable connector as well as on the sensor module.

  • Page 16: D-Sub Power Supply And Communication J1 (15Pol, 2 Rows)

    Position the LGD Compact module at the location where the measurement will be carried out and where computer, power supplies and gas delivery systems can be installed. For customer support and system service it is ideal if the computer also can be connected to the internet. To allow simplified connectivity for evaluation a cable integrating both, system power supply and RS232, are provided (straight RS232 version, not crossed).

  • Page 21: Gas Conditioning And Filtering Information

    2.4 Gas conditioning and filtering information The LGD Compact Gas Sensor Modules are based on an optical measurement technique where performance is directly linked to optical transmission through the measurement cell. Sample gas containing particles and aerosols are likely to contaminate the optical windows of the measurement cell and degrade the optical transmission more or less quickly.

  • Page 22: Zeroing And Purging

    Adjustment of the sensor calibration "Concentration_Offset" [ppm] and "Concentration_Span" [ppm] allows correcting the measured values with the linear function:         Offset Span meas In practice, the correction values are entered: e.g. if the measured offset is -1 ppm, 1 has to be entered under Customer offset, and if the slope for the span (or “gain”) is too steep by 5%, enter 0.95 under Customer Span to correct the slope.
