INTRODUCTION

M&C SP2500-H.. series probes are used for continuous gas sampling in dust-loaded processes at high
temperatures and high gas moisture.
The probe offers the possibility to remove the preliminary filter or sample tube in the process without
having to remove the probe head for cleaning purposes.
H/C/I/BB and ..-H/C/I/BB/F series probes are used in highly dust-loaded processes. The additionally
installed backpurging valve and pneumatic isolating valve in the sampled gas outlet ensure highly
efficient backpurging of the filter space in the in the probe head and used preliminary filter.

DESCRIPTION

The probe has been designed for easy installation, safe operation, easy maintenance and diversity in
application.
Depending on the particular problem, various sample tubes or preliminary filters (see data sheets 2.14
and 2.17), which are not included in the scope of supply of the probe, are screwed into the G3/4"i thread
in the filter holder.
The large, ceramic deep-bed filter element (optional glass fibre elements or glass wadding fillings
available) is arranged in a housing with minimal dead space outside the process area.
The probes are designed for replacement of the filter element without the need for tools; as the sample
line does not need to be removed, contamination of the clean gas side is avoided.
Cleaning of the sample tube or preliminary filter takes place by withdrawing the filter part from the probe
without having to remove the probe head.
Owing to the special design of the heating element of SP2500... series probes, the entire probe head
including mounting flange can be heated adjustable to 180°C, thus ensuring reliable operation without
cooling below the dew point externally. Temperature control with the standard version takes place by
means of an integrated capillary sensor thermostat with excess temperature limiter and alarm function
in a compact arrangement directly on the probe.
With the SP2500-H, backpurging or calibration gas supply takes place via an optional check valve
(option C).
Additional functions of the SP2500-H/C/I/BB(/F):
• The calibration gas can be supplied directly at the check valve/C to the probe outlet. Calibration
gas supply at the probe is possible without any expensive gas loss via the otherwise open probe
inlet.
• The isolating valve /I isolates the gas outlet of the heated filter chamber.
The filter space, sample tube or preliminary filter can be backflushed via the check valve /BB
•
projecting into the heated filter chamber.
