1.1
Main instructions for operation
WARNING: Danger resulting from escaping gas when the SR-unit is swiveled
out
Excess pressure in the gas duct can cause hot and/or noxious gases to escape
when the SR-unit is swiveled out.
b
Swivel the SR-unit out only when you have taken suitable safety measures.
CAUTION: If the hinge pin has not been correctly inserted (→p. 35, Figure 15),
the SR-unit can drop when swiveled out.
b
Check whether the hinge pin is completely pressed down before the SR-unit
is swiveled out.
CAUTION: Danger of contamination caused by purge air failure (for GM32
with GMP probe)
b
If a failure of the purge air supply occurs, take immediate measures to protect the measuring system (
1.2 Intended use
1.2.1 Purpose of the device
The GM32 serves exclusively for emission and process monitoring of gases in industrial
plants.
GM32 measures continuously directly in the gas duct (in-situ).

SOPAS ET (PC program)
SOPAS ET can be used to set the GM32 parameters and provides access to the GM32 logbook.
SOPAS ET runs on an external PC connected via the Ethernet interface (
GM32.
More information on SOPAS ET:
→ Technical Information GM32
→ SOPAS ET Help menu
2.4 Reference cycle
Correction of internal drifts in an adjustable interval (standard: 1 hour, setting: SOPAS ET),
via a command (with SOPAS ET) or via an external signal (option).
Measured value output during the reference cycle: Last valid measured value.
2.5 Check cycle
The check cycle is made up of the reference cycle, followed by the check and output of the
zero and check point (70% of upper measuring range value).
It is performed in an adjustable interval (with SOPAS ET), via a command (with SOPAS ET)
or via an external signal (option).
With the check cycle, the device is capable of performing the check of the zero point and a
reference point for each component without feeding test gases. The check cycle meets the
requirements of EN14181 and makes drift monitoring with test gases according to QAL3
unnecessary.
● Zero point
An internal zero point reflector is swiveled in time-controlled in adjustable intervals. The
emitted light is reflected back in the sender/receiver unit to the detector, the zero spectrum is evaluated with the calibration function and thus the zero points of all ducts
measured and output.
If the deviation from zero is > ±2% of the FS, Maintenance request is signaled.
● Check point
An internal swivel element with two reference filters and an NO-filled cell is swiveled in
during the check cycle in addition to the zero point reflector and the reference value or
concentration value measured. These check values are scaled to 70% of the selected
measuring range.
Maintenance request is signaled if the deviation from the setpoint value is > ±2% of the
FS.

● Signal during the check cycle: Not_measuring. (Optionally digital output or OPC inter-
face).
● The determined zero and reference values can be output on analog outputs depending
on the parameter settings:
– Directly after the check cycle.
– On request (via a digital input, option).
– Signal during the output: Output_control_values. (Optionally digital output or OPC

Design of GM32
The GM32 Probe version comprises
● Sender/receiver unit (SR-unit)
The SR-unit contains optical and electronic subassemblies.
The concentration calculation of the sample gas according to the absorption spectro-
scope principle is performed in the SR-unit.
● Measuring probe with flange resp. purge air fixture (

2.6.1
Measuring probe
Probe types:
● Measuring probe with open measuring gap (GMP probe)
GMP probes require a purge air supply to protect the window against contamination.
● Gas diffusion probe (GPP probe) with gas permeable ceramic filter.
GPP probes are fitted with an automatically controlled heater to prevent condensate on
the windows.
Both probe versions have an integrated temperature and pressure sensor.
2.7 Purge air unit (for GMP measuring probe)
The purge air unit supplies filtered ambient air to the purge air fixtures and protects the
windows of the SR-unit from contamination and high gas temperatures.
The purge air is blown into the gas duct through the “flange with tube”.

unit.

Preparation of sampling point
● The basis for the determination of the sampling point is the preceding proj-
ect planning (e.g. based on the SICK application questionnaire), the information in the final inspection record of the GM32 and the regulations of
the local authorities.
● The equipment operator is responsible for the determination of the sam-
pling point (e.g. the determination of a representative sampling point).
● The equipment operator is responsible for the preparation of the sampling
point (e.g. load carrying capacity of the welded flange).

3.2.2 Installing the “flange with tube” on the gas duct
WARNING: Danger resulting from gases in the gas duct
Hot and/or noxious gases can escape during work on the gas duct, depending
on the equipment conditions.
b
Work on the gas duct may only be performed by skilled persons who, based
on their technical training and knowledge as well as knowledge of the relevant regulations, can assess the tasks given and recognize the hazards
involved.
1 Make a cut-out in the gas duct for the “flange with tube”.
2 Insert the “flange with tube” so that the mark (TOP)
spective of the gas duct angle) and attach the “flange with tube”.
– The tube must project at least 30 mm into the gas duct.
– Make sure the probe does not collide with other devices or fittings.
– Tilt the tube slightly downwards (approx. 1°).
This allows any condensate to drain off.
3 Now fix the “flange with tube” properly to the gas duct.
Make sure that the alignment of the flange does not change.
4 If necessary, attach duct insulation (protect GM32 from heat).

When the gas duct is hot, insulate the duct and flanges so that the
GM32 is protected from excess temperatures (

b
Provide threaded bolts (4) to screw on the connection unit (→ p. 72, §31) and screw on
the connection unit.
