Special Features

Gas Sample Probe Series SP®

Version SP3200V and SP3200 for sampling
from Ex-zone 2 or 22

SP3200V/HEX5.1

Application

The M&C sample probes version SP3200V and

SP3200 are used for continuous extraction of

explosive gases (Ex-zone 2 or 22) from dust

loaden, high temperature and/or humid proc-

esses. The probes can be mounted in Ex-zone

2 or 22. Both versions differentiate only in the

sealing material of the filter housing. Version

SP3200V has got a sealing out of FPM for

types which are heated up to max.185°C

and version SP3200 has got a sealing out of

graphite for all versions heated up to more

than 185 °C.

Description

The sample probes are designed for easy

installation, reliable operation and trouble-

free maintenance. They are versatile in appli-

cation and depending on the task to be per-

formed, various pre-filters series V12 or V20

with integrated volume displacer, optional

with extension tubes, not included in the

scale of delivery, can be simply screwed into

the mounting flange of the basic probe. For

error control the sample gas flow rate has to

be monitored externally.
This M&C stainless steel or ceramic filter ele-

ment with a large surface and high capacity

is located in the external housing. The design

offers little or no stagnant space outside

the process. The probe housing is covered

with a protection shield which is part of the

Ex-approval.
The probes are designed in such a way that

changing the filter element is possible with-

out the use of tools. In this operation, neither

the sample probe tube nor the sample line

need to be removed, thus avoiding contami-

nation of the clean gas path and maintaining

the integrity of the system.
The special design of the optional heat-

ing of the M&C-probes version SP3200(V)

permits controlled heating of the com-

plete filter housing, including the mount-

ing flange. This ensures reliable operation

external to the process preventing the

temperature falling below the dew-point.

For M&C probe version SP3200(V), the heaters

version HEX5-1.08 or HEX5-2.08 are available

as option (see Data sheet 2-3.1).
Version HEX5-1.08 has got a temperature

controller integrated in the connection box

of the probe and is suitable for ambient tem-

peratures up to 50°C. Version HEX 5-2.08 is

equipped with a temperature controller in a

wall mounting case to be mounted externally.

When using this combination, the probe can

be used at ambient temperatures up to 70°C

and the controller up to 50°C.
The probe can be operated with both heat-

ing versions in Ex-zone 2 and 22 resp. Class I

Division 2, Groups A/B/C/D.
For calibration gas feeding or back-purging

different options are possible. For example

the option RS with mounted buffer vessel

triggered by an explosion-proof solenoid

valve is available . The back-purge pressure

has to be monitored externally and has to be

min. 1 bar higher than the process pressure.

For the pressure control while back-purging,

a corresponding special valve is mounted

in the sample gas outlet. Thus, an additional

solenoid valve to shut off the sample gas

outlet is not necessary.
The back purge inlet is shut off by a check

valve.
