2. Once the measuring head and reflector have been installed as shown in Fig. 5.10
or Fig. 5.18 , the 3 nuts on the respective flanges are tightened as described in the
points below.
3. By this means the optical alignment of the measuring head is performed at the
same time.
For this a sighting mechanism (Fig. on the left middle) is available on the measur­
ing head, which is located on the right side behind a sight glass. The image of the
reflector (spot of light) must be aligned so that it is positioned in the centre of the
sighting mechanism (see figure on the left, bottom). If necessary the reflector must
also be aligned (at right angles to the gas duct).
4. Now nut B is tightened first (Fig. on the left, top).
When the nut A is tightened, the measuring head changes its inclination relative to
the axis B - C and the image in the sighting mechanism moves in a horizontal di­
rection. Tightening or releasing the nut C causes a pivoting movement about the
axis A - B and the image in the sighting mechanism moves in the vertical direction.
Only tighten the (self-locking) nuts to such a degree that the disc springs can still
perform their spring action.
Parameterisation and operation of the measuring head
The device is supplied with factory settings. The calibration to the dust-free measuring
path is performed in the factory provided that the operating company has supplied a
completed measuring point questionnaire. After successful initial commissioning, the
parameterisation of the measuring head must be performed by software. The basic
parameters necessary for operation must be saved.
DURAG service technicians will be glad to assist you if required. They have the nec­
essary equipment and software. You can find the addresses and phone numbers of
the service engineers under DURAG GROUP company addresses.
Specific hardware and software are required for inputting or checking parameters. We
recommend the use of the optional D‑ESI 100 SET.
The standard interface for parameterisation is the USB port. To allow the use of this
port, the protective cap must be opened on the USB port of the measuring head (see
Fig. 5.12 ).
