Gas sampling and gas conditioning technology 2-1.0-ME
Probe Structure:
The filter housing with its all-round heating element forms a unit with the standard mounting flange
DN65 PN6 and the laterally mounted electrical connection socket.
Mounting jaws are located at the aperture on the underside of the outer protective casing. These have
an integrated silicon cap for the connection of heated M&C sampling tubes with external diameters
of
40 mm to a max. 55 mm.
The probe sample gas outlet connection has a ¼" NPT internal thread to which the customer must
connect a suitable size of temperature resistant and threaded connector to connect the sample line in
a gas tight manner. These connectors can be supplied by M&C.
After assembly of the bolted pipe joint and of the sampling tube the sample gas outlet connection is
enclosed with the red silicon insulation provided. The mounting jaws and the integrated silicon cap
close off the connection to the exterior.
In order to sample gases, a one-meter long, stainless steel sampling tube is mounted in the mounting
flange. The maximum operating temperature for the sampling tube is 600° C.
Depending on the process gas temperature and composition or critical set up situations, heated probe
elements made of stainless steel with flange connection DN65 PN are used:
Type Process
temperature Length
Standard/max. Tube, outer diameter
SP30H1, heating max. 320°C up to max. 550 °C 1,0m / 2,0m 40mm
SP30H2, heating max. 200°C up to max. 200 °C 1,0m / 2,0m 40mm
SP35H, heating max. 320°C up to max. 550 °C 0,175m 40mm
10 RECEPTION
The gas sample probe is normally delivered in two packaging units:
1. The gas sample probe with the screws, nuts and flange seal required for mounting.
2. Sample tube with gasket.
The gas sample probe should be removed carefully from the packaging and checked immediately for
completeness against the delivery note.
Check the goods for any damage incurred during transport and if necessary inform your transport
insurer of any damage.
11 PREPARATION AND 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.
