Embracing Challenge Gas Sample Probe Series SP® Version SP3100V and SP3100 for sampling from zones with explosive gas Special Features Approval according to ATEX for sam- pling from Ex-zone 0, 1 and 2 Approval according to ATEX for mount- Optimum operational reliability Universal applicability Adaption to nearly all process condi- tions due to its compact and modular design Easy mounting and maintanance Small volume, fast response time Application The M&C sample probes version SP3100V and SP3100 are used for continuous ­ xtraction of e explosive gases (Ex-zone 0, 1 and 2) from dust loaden, high temperature and/or humid processes. The probes can be mounted in Ex-zone 1, 2, 21 and 22. Both versions differentiate only in the sealing material of the filter housing. Version SP3100V has got a sealing out of FPM for types which are heated up to max.185°C and version SP3100 has got a sealing out of graphite for all versions heated up to more than 185 °C. Description The sample probes are designed for easy installation, reliable operation and troublefree 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 (see page 4 and data sheet 2-1.1.0.8), 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 ­ntegrity of the system. i The temperature control of the M&C-probes version SP3100(V) can be done by three different heater types. The first possibility is a self-regulating heater version HEX4-135 or HEX4-180 (see data sheet 2-3.2) for Ex-zone 1 and 21, for gas sampling from zone 0, 1 or 2. In dependence on the ambient temperature and the heater type, the min. temperature in the probe is 90°C resp. 120°C, the max. temperature is 120°C resp. 160°C. The second possibility is a controlled heating version HEX1-3 for Ex-zone 1, adjustable up to 180 °C and for sampling from Ex-zone 1 or 2. The controller has to be mounted outside the Ex-zone. The third possibility is a controlled heating version HEX1-1 for Ex-zone 1, adjustable up to 180 °C and for sampling from Ex-zone 1 or 2. The controller can be mounted inside the Ex-zone. 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 1 and 2. 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. The special design of the optional heating of the M&C-probes version SP3100(V) permits controlled heating of the complete filter housing, including the mounting flange. This ensures reliable operation e ­ xternal to the process preventing the temperature ­ alling below the dew-point. f Technical specifications and illustrations are without obligation, subject to modifications. 10.04/11.12 M&C TechGroup Germany GmbH • Rehhecke 79 • 40885 Ratingen • Germany info@mc-techgroup.com • www.mc-techgroup.com • Fon +49 2102 935-0 • Fax +49 2102 935-111
