Chapter 1 _________________________________________________________________________________________ 1.1 Broad Overview The 1316A-2 Multi Gas Monitor simultaneously measures the concentration of up to 4 Gases. The concentration of each gas is expressed as ppm or a volume percentage referenced to dry gas condition. The measurement principles are based on Non Dispersive Infrared (NDIR) and Electrochemical Sensors. A full discussion of these principles is contained in section 1.4.
Chapter 1 _________________________________________________________________________________________ Fig.1.1 Flow diagram of the 1316A-2 Multi Gas Monitor 1.2.2 NDIR Module and UA1372 Module (Optional) Measuring System This block is the heart of the monitor. It contains the Infrared source the sample cell and the Detector with specialized optical filters and processing electronics necessary to do highly accurate measurement of gas concentrations.
Chapter 1 _________________________________________________________________________________________ 1.2.3 Power Supply The power supply included in the 1316A-2 can be directly connected to a wide range of single phase mains supplies and still be able to produce the stable voltages required to keep the monitor within calibration. 1.3 Software Description The BZ6013 software is menu driven specifically written to control the 1316A-2 monitor.
Chapter 1 _________________________________________________________________________________________ The NDIR Module and the Electrochemical Sensors are to be specified prior to purchase. The Multi Gas Monitor INNOVA 1316A-2 is delivered as specified by the Customer. 1.
Chapter 1 _________________________________________________________________________________________ Fig.1.2 Simple NDIR Gas Monitor 1.4.2 The Infrared Transmission Spectra. The concentration of a subject gas in the sample is computed as a function of the light intensity measured by the detector. The figure below characterizes the band pass filters for Freon and CO2 gases. Filter Centre Wavelength μm Freon Carbon dioxide Band Width μm Centre Wavelength cm-1 Band Width cm-1 8.73 1.24 1145 163 4.
Chapter 1 _________________________________________________________________________________________ IR SOURCE SAMPLE CELL BAND PASS FILTERS ELECTRONICS Fig.1.4 The Optics of the NDIR Module. Sample Cell The sample cell is a gold-coated glass chamber that provides a means for the infrared source to pass through the sample gas. Infrared-transparent sapphire windows are provided at each end of the cell.
Chapter 1 _________________________________________________________________________________________ System Board Assembly The system board assembly is a surface-mount printed circuit board that includes the digital and analogue electronic components and the IR detector assembly. The IR detector assembly includes thermopile IR detectors for the Freon, CO2 and reference channels. Light passed through the band pass filters is directed through the thermopile window to a detector substrate.
Chapter 1 _________________________________________________________________________________________ Sample Cell Temperature: The Module sample cell temperature is monitored by a thermistor in contact with the sample cell. This temperature measurement is used as follows: An “out of range” sample cell temperature condition causes Freon and CO2 data to be declared “data invalid.” Sample Cell Temperature Out Of Range is set when the Sample Cell Temperature is not within its allowed range.
Chapter 1 _________________________________________________________________________________________ 1.4.6 The O2 and NO Measurement O2 and NO gas concentration are measured using electrochemical (fuel cell) sensors. A fuel cell sensor provides an electrical response that is proportional to the concentration of the sample gas. The NDIR Module sample-cell exhaust is directed to UA1372 manifold for O2 or O2/NO measurement. Sample gas is delivered to the O2 and NO sensors through this manifold.

Chapter 4 _________________________________________________________________________________________ 4.1 Introduction 4.1.1 Factory calibration Multi Gas Monitor –INNOVA 1316A-2 component tolerances result in small, but relevant differences in measurement of a given gas concentration. The IR source, pressure transducers, thermistors, band pass filters, and detectors are subject to these variances. During the Type 1316A-2 manufacturing process, each unit is individually characterized.
Chapter 4 _________________________________________________________________________________________ Figure 4.1. Status Window displaying “Zero required”. During a zero point calibration the sample gas is taken through the Zero inlet on the rear panel of the monitor with a flow rate of 700 ml/min. ambient air is used for the zero calibration. Zero Request The Zero Request (see figure 4.1) is set true under the following conditions: At POR (power on / reset).
Chapter 4 _________________________________________________________________________________________ Purpose Zero calibration compensates for conditions that affect gas concentration measurement. Examples of these conditions are as follows: Changes in ambient temperature. Short-term sample cell contamination caused by inadequate particle filtering. Long-term sample cell contamination caused by deposits on the sample cell wall or windows.
