This handbook provides a description of the construction and functional principle of the
“Cong Prima 2M” dew point analyzer (also referred to as the CP 2M, transducer, analyzer or
DPA).
The CP 2M is a through-flow automatic hygrometer. It takes direct measurements with the
aid of a thermostatically controlled mirror. Dew point (dp) is established by monitoring the
reflectivity of the mirror. As the temperature of the mirror is lowered, the surface becomes
less reflective due to the formation of condensation. The temperature at which condensation
occurs is the dew point.
1 Description of the CP 2M
1.1 Intended use of the CP 2M
!
The CP2M is designed to automatically measure the dew point of water (dpW) and the dew
point of hydrocarbons (dpHC) at gas measuring facilities. It is also suitable for use in various
operations and procedures where gas quality must be monitored.
The analyzer can measure the dew point of hydrocarbons when the gas being examined
is free of water vapor that would condense at a higher temperature than that of hydrocarbons.
The analyzer can measure the dew point of water without regard to hydrocarbon
condensation temperature.
1.2 Measurement principle
!
The CP 2M makes use of the “total refraction” effect to determine the dpW.
Total refraction occurs when polarized light, with a particular orientation, passes through the
interface between a heterogeneous media (gas) and a reflective surface (thermostatically
controlled mirror) at a specific angle of incidence know as Brewster’s Angle.
When total refraction occurs no light is reflected.
The analyzer uses a laser as a source of polarized light.
The reflective surface is a dielectric condensation mirror made of silicone.
When the mirror is clean, that is when no condensation is present, as the beam of light from
the laser encounters the gas/mirror interface it is completely refracted. As a result, no light is
reflected onto the photo detector, which therefore registers a null signal.

emitting diode; F1 and F2 –photo detectors of the registration system; U0– Zero signal from
the photo sensor.
As the mirror is chilled, droplets of water condensation begin to form on the mirror’s surface.
The rays of polarized light emitted from the laser diode are scattered when they strike these
droplets and are registered by the photo detectors (F1).
The signal created by photons hitting the detector (Illus. 2.1) is boosted and registered by the
detection system (Illus. 2.1). The signal intensity is dependent on the amount of water
condensation on the chilled mirror’s surface.

In the absence of water vapor, hydrocarbons in the sample gas condense onto the surface of
the chilled mirror. Instead of droplets, this condensation forms a smooth film. The build up of
a cohesive film on the mirror’s surface alters the angle of incidence at which the polarized
light rays encounter the surface of the mirror.
As the light strikes the gas/condensation film interface it is partially reflected.
At the same time, due to the transparency of the condensate film, some of the light will only
be reflected at the next boundary, the interface of the condensation film with the mirror’s

surface. As a result, the photo detector F2 receives two sets of reflected light rays, which are
slightly out of phase.
The light signal registered by the detection system produces a characteristic interference
pattern.
The intensity of the light received by the photo detector is directly dependent on the amount
of hydrocarbon condensation on the mirror’s surface. As more hydrocarbons precipitate onto
the mirror the film becomes thicker, this in turn means that the distance between the two
upper and lower boundary interfaces becomes greater. This increase in distance correlates
to a greater phase discrepancy between the two reflected rays that increases the signal
strength.
The registration of the hydrocarbon dew point temperature occurs as soon as the
condensation film reaches a thickness of 5 –10nm (default setting).
In this way, these two separate modalities generate two separate signals: the signal from
photo detector F1 is used to establish the dpW and the signal from photo detector F2 to
establish the dpHC (Illus. 3.1 and 3.2).

1.3 CP 2M provision for explosion protection
The CP2M is certified as compliant with the requirements of EN 60079-0:2009, EN 60079-
1:2007. It carries the explosion protection marking II 2G EEx d IIA + Н2T5.
This marking identifies the CP 2M as a “flameproof enclosure” as per the requirements
stated in EN 60079-1:2007.
Explosion protection is provided by encasing the electrical elements of the electronics unit in
an enclosure that is mechanically robust and meets the standards of EN 60079-0:2009. This
enclosure can withstand explosion pressures and prevent combustion from escaping into an
ambient explosive environment.
Integrity of the flameproof enclosure is maintained through the use of threaded and
cylindrical flameproof joints. A drawing of the explosion protection measures (Appendix С)

identifies these connections as “Explosion” and lists the allowable explosion protection
tolerances according to EN 60079-1:2007.
The removable enclosure lids have an inscribed warning:
«ОТКРЫВАТЬ, ОТКЛЮЧИВ ОТ СЕТИ ~ DO NOT OPEN WHEN ENERGIZED ».
1.4 Analogue and digital connection ports
!
In order to connect the Cong Prima 2M to a technical-information measuring system or
facility, the analyzer is equipped with a serial interface.
The interface installed can be for the transmission of either analogue or digital signals
depending on the customer’s requirements.
• digital port !RS 485 Modbus
• analogue port !4 –20 mА.
The selection of either a digital or analogue information transfer port is made when the CP
2M is originally ordered.
If no specification is made with regard to interface preference, the analyzer will be delivered
with an analogue port (4 –20 mA).
Digital port: RS485:
The digital port provides for the transfer of measurement data to an external system using
the Modbus / RTU protocol (see Appendix O).
The interface is galvanically insulated (up to 500 V DC).
Analogue port 4 –20 mA:
Depending on the measurement mode selected, either the dpW or dpHC values are sent to
the interface port. The maximum impedance load on each output should not exceed 400
ohms.
The port is passive, meaning that the power supply for the CP 2M is delivered from an
external source. This connection is galvanic insulated up to 500 V DC.
The digital and analogue signals for measured dew point values (dp) correspond to the
following equation:
dp = 3.75 (I –4) –30
I = 0.267 (ТР + 30) + 4
(for water and hydrocarbons in the temperatures range: –30 °C to +30 °С)
⇒the value 4 mA corresponds to a dew point temperature (dp) of –30°С
⇒the value 20 mA corresponds to a dew point temperature (dp) of +30°С

1.5 Identification and user interface
!
To operate the CP 2M, a magnetic key is used to select, alter, and enter parameter
values. The arrows above, below, and to both sides of the display located on the front of
the analyzer indicate the location of the buttons that are activated by the magnetic key.
The magnetic key is included with delivery of the analyzer.

The CP 2M’s menu consists of seven main headings, corresponding to the analyzer’s most
important functions (illus. 7).
When switching on the CP 2M, be sure to allow the software to fully load before taking dew
point measurements.
The software must also be fully loaded before making any menu selections.
