12 PREPARATION FOR INSTALLATION
 Select the optimal sampling point in accordance with the generally applicable guidelines or
consult the competent persons.
 Locate the sampling point in such a way that there is adequate space for inserting and
removing the probe and pay attention to the insertion length of the probe tube.
 Make certain that the probe is easily accessible so that you can carry out any subsequent
maintenance work without trouble.
 Locate the probe connections in such a way that the connections' temperature is always above
the acid dew point in order to avoid corrosion and blockage problems. If this is not possible, a
heated SP35/SP30 probe tube is recommended for cold connections.
 If the ambient temperature in the area of the connections is >80°C as a result of radiated heat,
a radiated-heat deflector must be mounted to protect the probe.
 The connection's mounting flange connection should comply with DN65 PN6. If other
connection sizes are required, a special adapter flange /S010 can be supplied as an option.
 Before mounting, the probe must be adapted to the existing operating conditions.
The existing operational parameters are to be checked accordingly prior to commencing mounting

13 MOUNTING
M&C
SP180-H probes are designed for stationary use and if properly selected and mounted a long
service life and minimum maintenance are guaranteed. It is advisable to mount the probe in an
operational position which is at a 10% inclination to the process. See also Figure 2 for the following
description.
 Screw either the probe tube directly into the ¾" inner thread  in the flange of the probe with
the ¾" flat gasket  and tighten.
 For mounting of the SP180-H at the sampling flange loosen the metal clamp  around the heat
insulating protection cover and remove the cover .
 If the probe connection does not correspond to the standard flange connection DN65 PN6, an
optionally supplied adapter flange  should be mounted to the probe (see Figure 2).
 If the heated probe tube type SP30/35 is used then the probe is to be screwed to its flange
(with welded threaded bolt). First insert the flange seal  between the two flanges.
 Attach the flange seal  to the probe connection.
 Insert mounted probe tube into the connection piece and fasten the probe using the screws
and nuts supplied.
