Special Features
Gas Sample Probe Series SP®
Version SP2500-H, SP2500-H/C/I/BB, SP2500-H/C/I/BB/F
SP2500-H/C/I/BB/F/1K190
Application
The gas sample probes M&C type SP2500...,
based on version SP2000-H (see data sheet
2.2.2), are used for continuous gas sampling
in processes with gases of high dust con-
tent, high temperatures and/or high humid-
ity. They make it possible to remove e.g. for
cleaning purposes the preliminary filter or
the sample tube out of the process without
dismounting the complete gas sample probe.
The probes type SP2500-H/C/I/BB and
SP2500-H/C/I/BB/F with special back purge
possibility are used in case of very high dust
content. For this purpose, they are equipped
with an additional back purge valve and a
pneumatic check valve in the sample gas
outlet.
Description
The M&C gas sample probes are designed for
easy installation, reliable operation, trouble-
free maintenance and universal applicabil-
ity. Depending on the application, different
sample tubes or prefilters (see data sheets
2-1.1.0.6 and 2-1.1.0.8), not included in the
scope of delivery of the probe, are screwed
into the thread (G3/4”i) of the filter housing.
The large surface ceramic filter element (also
glass fiber elements or spun glass fillings
are available) is placed in a housing with low
stagnant space outside the process.
The M&C gas sample probes are designed
so that changing a filter element does not
involve the use of tools. In this operation the
sample line does not need to be removed,
thus avoiding contamination of the clean gas
path and also maintaining the integrity of the
system.
The cleaning of the sample tube or the pre-
liminary filter can be effected by extracting
the filter from the probe.
The special design of the heating element of
the SP2500... (with protective hood) permits
controlled heating of the complete filter
housing, including the mounting flange up
tp 180 °C. This ensures reliable operation
external to the process preventing the tem-
perature falling
below the dew-point.
The temperature of the standard probe is
controlled by an integral compact design
capillary sensor thermostat with an excess
temperature limit switch and an alarm
function for temperature failure. The probe
SP2500-H provides the possibility to feed the
test gas /C optionally via a check valve.
Additional functions of the probe SP2500-
H/C/I/BB(/F):
•
Calibration gas will be injected into
the probe through a check valve /C
directly to the sample outlet. No cali-
bration gas is lost into the stack.
• An isolation valve with pneumatic con-
trol /I shuts off the sample outlet from the
internal filter area.
• Through a high flow rate check valve /
BB, which is fixed to the internal probe
area, blow back of the filter housing
area and the insitu probe tube will be
done.
• Through a high flow rate check valve
/BB/F, which is fixed to the filter hous-
ing wall, blow back of the incorporat-
ed ceramic filter will be done incl. the
filter area and the insitu probe tube.
