9 APPLICATION
The M&C gas sample probes type SP2000... , SP2300-H and SP2400-H are used for continuous extraction of gases
from dust laden, high-temperature and/or humid processes.
10 DESCRIPTION
The sample probes are designed for easy installation, reliable and flexible operation and trouble-free maintenance.
Depending on the problem, different sample tubes or prefilters (see data sheet 2.14 and 2.17) are screwed into the
thread (G 3/4” i) in the mounting flange. This equipment is not included in the scope of delivery of the probe.
The large-surface ceramic deep filter element (fibre glass or glass wadding fillings are also available) is placed in a
housing with small dead volume outside the process area. The probes are designed so that no tools are necessary
for changing the filter element, the sample line needs not to be dismounted and no contamination on the clean
gas side will occur. Cleaning or back purging of the sample tube is possible from outside.
Due to the special execution of the heating element of the
SP2000-H, SP2300-H and SP2400-H (with protection
cover), the complete filter housing including mounting flange is heated, adjustable up to 180 °C [356 °F] (version
H320/C up to 320 °C [608 °F]), so that a safe operation without shortfall below the dew point in the out-of-process
area is guaranteed. The temperature adjustment of the standard version is made via an integrated capillary sensor
thermostate with exess temperature limiter and alarm function in compact configuration. Calibration gas feeding
and comparison sampling at the probe are possible.
Depending on the gas composition, it may be possible that the standard material of the probe body (stainless steel
1.4404) is not sufficient with respect to ist corrosion resistance. For this case, the
SP2300-H of PTFE is available or
alternatively for a heating above 180 °C [356 °F] the SP2400-H out of titanium.
