3.1.2 KRAY 2.848.015 version equipped with
insertable sampling probe
(Appendix C)
Some configurations of the Cong Prima 2M dew point analyzer are equipped with an
insertable gas-sampling probe.
The insertable sampling probe makes it possible to mount the analyzer directly onto the gas
line (min. ø 200mm) and ensures that the gas sample is clean.
This version of the analyzer is suitable for use in gas transport facilities and other
installations where the composition of the gas does not include liquid contaminants
(aerosols).
The gas delivery unit is outfitted with a cut-off valve. Thank to this valve, it is not necessary to
interrupt pipeline gas flow when the analyzer is temporarily uninstalled, for example for
maintenance procedures.
In addition, the KRAY 2.848.015 version has a fine-tuning valve used to adjust the volume
flow of sample gas to the CP 2M’s measurement chamber.

CP 2M protective equipment for outdoor installations
For outdoor installations, it is recommended that the CP 2M KRAY 2.848.015 be outfitted
with the insulated hood or weather shade included with delivery, in order to protect it from the
effects of inclement weather. The insulated hood prevents excessive cooling of the CP 2M’s
measurement chamber and sample delivery pipe by retaining the heat generated by the
measurement process as well as ambient heat within the gas pipeline (illus. 14). The
insulated hood and weather shade are included with delivery in the KRAY 2.848.015 version
of the Cong Prima 2M.
