Embracing Challenge Special Features ■ Approval according to ATEX, CSA and FM for sampling from Ex-zone 2 or 22 resp. Class I Division 2 ■ Approval according to ATEX, CSA and FM for mounting in Ex-zone 2 or 22 resp. Class I Division 2 ■ Different options for test gas feeding, back purging and shut-off ■ Optimum operational reliability ■ Universal applicability ■ Adaption to nearly all process conditions due to its compact and modular design ■ Easy mounting and maintanance ■ Small volume, fast response time 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 processes. 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 (365 °F). Description The sample probes are designed for easy installation, reliable operation and trouble-free maintenance. They are versatile in application and depending on the task to be performed, 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 element 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 without the use of tools. In this operation, neither the sample probe tube nor the sample line need to be removed, thus avoiding contamination of the clean gas path and maintaining the integrity of the system. The special design of the optional heating of the M&C-probes version SP3200(V) permits controlled heating of the complete filter housing, including the mounting 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 2.13). Version HEX5-1.08 has got a temperature controller integrated in the connection box of the probe and is suitable for ambient temperatures up to 50 °C (122 °F). 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 (158 °F) and the controller up to 50 °C (122 °F). The probe can be operated with both heating 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. When sampling from Ex-zones, back purging is only allowed with a gas suitable for the sampling point.
