Embracing Challenge [ M&C®| Gas Sample Probe Series SP® ^5^ Version SP3000 for sampling from zones with explosive dust SP3000V/RS/HEX4-135 resp. 180 Special Features ■ Approval according to ATEX for sampling from Ex-zone 20, 21 and 22 ■ Approval according to ATEX for mounting in Ex-zone 1, 2 or 21, 22 ■ 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 SP3000 are used for continuous extraction of explosive gases (Ex-zone 20, 21 and 22) from dust loaden, high temperature and/or humid processes. The probes can be mounted in Ex-zone 1, 2 or 21,22. 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/ V20 with integrated volume displacer and optional with extension tubes, not included in the scale of delivery, can be simply screwed into the mounting flange of the basic probe. These process-internal M&C pre-filters are necessary for a valid Ex-approval of the M&C-probes type SP3000. For error control of the pre-filter the sample gas flow rate has to be monitored externally. The probe-internal M&C stainless steel 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 SP3000 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. The temperature of the M&C-probes version SP3000 is controlled by a self-regulated heater version HEX4-135 or HEX4-180 for Ex-zone 1 and 21, temperature class T4 resp. T3 and for gas sampling from zone 0, 1 or 2. In dependence of the ambient temperature and the heater version, the min. temperature in the probe is 90 °C (194 °F) resp. 120 °C (248 °F), the max. temperature is 120 °C (248 °F) resp. 160 °C (320 °F). For back-purging the M&C pre-filter, the option RS is available with mounted buffer vessel triggered by an explosion-proof solenoid valve. With the mounted option for back-purging type RS, gas can be sampled from zone 20, 21 and 22. 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.
