The California Analytical Models 601-2-3 NDIR/O2
digital analyzer
product line is designed around a state of the art 16 bit
microprocessor, with 16 digital inputs, 16 digital outputs, 16 analog
inputs and 4 analog outputs. The analyzer can be manually operated from
the keypad or remotely via TCP/IP, RS-232C communications and discrete
inputs. The analyzer display includes screen presentation of all
analyzer alarms. Four levels of password protection are provided. For
precision measurements, the analyzer’s accuracy is increased
by
entering calibration curve fit polynomials. Automatic calibration may
be activated locally or remotely and includes auto cal via preset
times.
METHOD OF OPERATION
The California Analytical Instruments’ NDIR
analyzer is based on the
infrared absorption characteristics of gases. Using a single infrared
beam to measure gas concentrations, this analyzer produces highly
stable and reliable results. A single infrared light beam is modulated
by a chopper system and passed through a sample cell of predetermined
length containing the gas sample to be analyzed. As the beam passes
through the cell, the sample gas absorbs some of its energy. The
attenuated beam (transmittance) emerges from the cell and is introduced
to the front chamber of a two-chamber infrared microflow detector. The
detector is filled with the gas component of interest and consequently
the beam experiences further energy absorption. This absorption process
increases the pressure in both of the chambers. The differential
pressure between the front and rear chambers of the detector causes a
slight gas flow between the two chambers. This flow is detected by a
mass-flow sensor and is converted into an output signal.
METHOD OF OPERATION - OXYGEN
The
California Analytical oxygen analyzer section utilizes the paramagnetic
method to determine the percent level of oxygen contained in the sample
gas. The oxygen level is displayed on the LCD panel in engineering
units.
