• Metrology labs
The OptiSonde chilled mirror hygrometer is a National
Institute of Standards and Technology (NIST) traceable
humidity transfer standard at an exceptional value. The
compact rugged analyzer is connected to either a single-or
two-stage chilled mirror sensor and PRTD. Chilled mirrors are
the humidity sensors of choice when laboratory and process
measurements require high precision without long-term
drift. An LCD indicates two simultaneous user-configured
parameters. OptiSonde provides two user-configured analog
(4 to 20 mA) outputs. The display and front panel keys enable
quick and easy configuration.
The OptiSonde easily records humidity and temperature
data from a wide variety of applications. The analyzer is
equipped with a data logger capable of recording for 100
days at a sample rate of 1 second and is equipped with an
internal real-time clock. The saved data is uploaded to a PC
using terminal software as ASCII delimited text, enabling it
to be opened by Excel® and other spreadsheet programs for
data reduction, graphing and statistical analysis.
Theory of operation
Chilled mirrors fundamentally measure the dew or frost
point temperature by controlling a reflective surface to an
equilibrium temperature between dew/frost formation and
evaporation and precisely measuring the temperature of the
mirror at this point.
The chilled mirror sensors consist of a small polished
hexagonal rhodium, or platinum mirror attached to a
thermoelectric cooling module (TEC). OptiSonde’s servo
controller applies current to the TEC, which causes the mirror
to cool. The mirror is illuminated with a regulated Gallium
Arsenide (GaAs) emitter that transmits light in the infrared
spectrum. The light reflected by the mirror is received by
a photo detector. When water vapor condenses on the
mirror as water or frost (ice crystals), the light received
by the photodetector is reduced due to scattering. This
results in the servo controller reducing the power, causing
the mirror to slightly warm. OptiSonde’s control system will
modulate the amount of current flowing though the TEC to
maintain a temperature where the rate of condensation
and evaporation of water molecules and the mass of water
on the mirror are constant. The resulting temperature of the
mirror is then, by definition, equal to the dew or frost point
temperature. A precision four-wire platinum RTD embedded
in the mirror measures the temperature. The accuracy of the
dew point measurement has been validated to an accuracy
of ±0.2°C dew/frost point.
Dry bulb temperature is measured with a precise four-
wire 100W platinum RTD. The dew/frost point and dry bulb
RTD resistance signals are conditioned and amplified by
OptiSonde’s monitor to display and transmit dew/frost point
and temperature.
The cardinal measurements of dew/frost point and dry bulb
temperature, along with pressure and molecular weight
constants, are used to calculate other humidity parameters,
such as relative humidity, wet bulb, ppmv, ppmw,
absolute humidity, and water vapor pressure values using
psychometric equations.
The RTD sensor, which is embedded in the chilled mirror,
never comes in contact with the process or test environment.
The wetted parts consist of the platinum or rhodium mirror,
Mylar® or stainless steel vapor barrier and epoxy sealant.
The net result is drift free humidity measurement designed to
maintain accuracy specifications for many years.
Chilled mirrors require a nominal flow rate across the mirror
to achieve the optimal dew/frost formation and response
time. The sensor should either be installed in a duct with
moving air or be equipped with a sampling pump. The
optimum flow rate is 0.5 to 2.5 SCFH (0.25 to 1.2 L/min).
Panametrics provides sampling systems to condition the
temperature, regulate the pressure and filter process air
before reaching the chilled mirror. Our applications engineers
would be pleased to discuss your application in detail and
provide a recommendation for the system best suited to
your needs.
Analog control
Digiloop control
GE developed Digiloop™ control to overcome the
limitations of traditional analog PID (Proportional
Integral and Derivative) control. Analog temperature
control produces oscillations particularly at high or
trace humidity levels. It is difficult to apply self-tuning
or PID constants to analog control loops, which are
over damped or under damped. Digiloop utilizes digital
sampling and feed-forward control by taking time-based
samples when the dew point is within a predetermined
proportional band. By recording the oscillations, the
digital control effectively predicts the magnitude of
change and adjusts the current to the thermoelectric
cooling module, which steps the mirror temperature in
0.09°F (0.05°C) increments. This results in a significantly
improved control and dew point precision.

Contamination control and self-cleaning mirrors
For environments where physical contaminants such as
dust, oil mist and pollen are present, the use of a sampling
system with a filter media is recommended. The filter media
must be hydrophobic so as to not absorb or release water
vapor into the test stream. Over time the mirror can be
etched or pitted by particulates that lead to altering the light
scattering characteristics. The mirrors are field replaceable.
The standard rhodium mirror may be upgraded to platinum
for industrial applications. The two stage sensors also utilize
stainless steel wetted surfaces.
PACER® (Program Automatic Error Reduction) is a patented
contamination compensation scheme. The PACER cycle may
be initiated manually or by programming a timed cycle. The
cycle starts by capturing the data (during the PACER cycle a
constant reading can be transmitted via the analog outputs)
and cooling the mirror well below the dew point such that a
thick dew layer forms on the mirror.
The mirror is then rapidly heated. During the heating a
significant amount of soluble and some non-soluble
contamination is flash evaporated. The contamination left
on the mirror tends to aggregate in “dry islands” or “spots”\
(much like a glass that comes out of a dishwasher). This
process leaves approximately 85% of the mirror clean. The
light signal received by the photodetector is compared
against a reference LED/photodetector and the two signals
are “balanced,” effectively negating the effect of the residual
contamination left on the mirror.

The PACER cycle works very well, but eventually manual
cleaning may be required. All the chilled mirror sensor
surfaces are accessible for manual cleaning. Cleaning is a
simple process consisting of wiping the mirror with a cotton
swab wetted with cleaning solution or distilled water.

Question(s) liée(s) :
Sur l'hygromètre à miroir refroidi de PANAMETRICS, la sonde humide le capuchon a un petit trou et nous nous demandons si ce trou doit être aligné au trou inférieur sur la sonde ou décalé pour que ce soit fermé en fait?
Je cherche le schéma de connexion du câble qui relie le capteur à l' afficheur ( correspondance des numéros) pour cet hydromètre à miroir refroidi svp?
Après avoir remplacé l'alimentation 12V dans un boitier mural Optisonde GE, il n'y a plus d'affichage sur le LCD. Où puis-je envoyer cet appareil pour le reprogrammer ?
Qu'est-ce que la température de rosée? Quelle différence avec le point de rosée ?
