7-2 Chapter 7: Configuration SHB_U14
Hardware configuration
Module hardware
structure
The Uras 14 analyzer module is equipped according to the measurement task
involved.
The REKONUR message establishes the correct equipment configuration.
• The analyzer module can be configured for thermostat and non-thermostat
versions.
The module is generally equipped with hardware for the thermostat version.
• The modulator contains one or two emitter inserts.
Design versions • The hardware configuration is established using the REKONUR configuration
program.
For the measurement components the following information is entered:
• Sample cell length
• IR detector placement
• If applicable, the type and placement of optical filters
• If applicable, information on calibration cell fill concentration
• Chapter 2 contains a general overview of the possible module versions.
Emitter
Possible emitter power levels:
Emitter 1: 2.2 W, 3.7 W, 5.2 W
Emitter 2: 2.2 W, 3.7 W, 5.2 W
Emitter power is set using the test and calibration software.
Sample Cell
RECONUR prompts guide the sample cell selection process.
Lengths: 0.3 mm, 0.6 mm, 2 mm, 6 mm, 20 mm, 60 mm, 200 mm
Material: Aluminum, gold-plated aluminum
Aluminum cells from 200 to 60 mm in length are used to measure CO, SO
2
and NO
in flue gases.
To measure NO in ranges <650 mg/m
3
, the filter cell (part number 0768 483) and a
200-mm aluminum cell are used.
See Chapter 2 for the appropriate stainless steel or plastic tubing connections.
Calibration unit
Depending on the measurement task contemplated, install the calibration unit with
or without optical filter.
Optical filter
Install per REKONUR prompts.
Use the clamp ring with part number 0801 935 when installing between 2 IR
detectors or between the sample cell and IR detector.
