3 Description and construction
of the Cong Prima 2M
The Cong Prima 2M dew point analyzer comprises the sensor cell (1), the housing (2), lids A
(3) and B (4), the gas supply line (5) and an electronics unit, which is located within the
housing (2) (see Appendix B).
The analyzer is equipped with four magnetically activated buttons, which are arranged above,
below, and to either side of the display screen. These buttons are operated using a specially
designed magnetic key.
The CP 2M’s display screen shows the current dew point measurement values, dpW or
dpHC, and other information about the status of the device.
The terminal block of the analyzer’s transformer is covered by lid B. The RS485 or
4 –20 mA data ports are located in the terminal block, which is also the pint of connection for
the four-conductor power cable. The power cable passes through the housing into the
electronics unit by way of the cable inlet (8).
The numbers and uses of the terminals are given in appendix A.
The CP 2M is attached to the gas supply line with eight stainless steel M8 screws (6). The
construction of the analyzer permits easy access to the thermostatically controlled mirror for
cleaning and maintenance purposes. Gas delivery to the CP 2M’s measurement chamber
must be interrupted for the duration of these procedures.
3.1 Cong Prima 2M configuration options
The Cong Prima 2M dew point analyzer is available in three versions with different
configurations.
3.1.1 KRAY 2.848.015-01 version
(Appendix B)
The KRAY 2.848.015-01 version consists of a measurement module with no pre-installed
system for gas delivery, filtration or outflow.
This module is particularly suited for applications in laboratories and industrial areas where
gases are characterized by a high degree of purity.
The KRAY 2.848.015-01 version can also be installed as a dew point analyzer in
measurement systems that are already installed.
