Special Features

Gas Sample Probe Series SP®

Version SP3100V and SP3100 for sampling from

zones with explosive gas

SP3100V/RS/HEX4-135 resp. 180

Application

The M&C sample probes version SP3100V and

SP3100 are used for continuous extraction of

explosive gases (Ex-zone 0, 1 and 2) from dust

loaden, high temperature and/or humid proc-

esses. The probes can be mounted in Ex-zone

1, 2, 21 and 22. Both versions differentiate only

in the sealing material of the filter housing.

Version SP3100V has got a sealing out of FPM

for types which are heated up to max.185°C

and version SP3100 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 (see page 4 and data

sheet 2-1.1.0.8), 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 SP3100(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.

The temperature control of the M&C-probes

version SP3100(V) can be done by three dif-

ferent heater types.

The first possibility is a self-regulating heater

version HEX4-135 or HEX4-180 (see data sheet

2-3.2) for Ex-zone 1 and 21, for gas sampling

from zone 0, 1 or 2. In dependence on the

ambient temperature and the heater type,

the min. temperature in the probe is 90°C

resp. 120°C, the max. temperature is 120°C

resp. 160°C.

The second possibility is a controlled heating

version HEX1-3 for Ex-zone 1, adjustable up

to 180 °C and for sampling from Ex-zone 1 or

2. The controller has to be mounted outside

the Ex-zone.

The third possibility is a controlled heating

version HEX1-1 for Ex-zone 1, adjustable up

to 180 °C and for sampling from Ex-zone 1 or

2. The controller can be mounted inside the

Ex-zone.

For back-purging the M&C pre-filter, the

option RS is available with mounted buffer

vessel triggered by an explosion-proof sole-

noid valve. With the mounted option for

back-purging type RS, gas can be sampled

from zone 1 and 2. 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.

When sampling from Ex-zones, back

purging is only allowed with a gas suit-

able for the sampling point.
