Optica™

The next generation humidity
reference standard
Optica Series chilled mirror hygrometers offer National
Institute of Standards and Technologies (NIST)—traceable
humidity, temperature and pressure measurements forthe connected generation. Now data is accessible fromanywhere, any time, from within a browser over the Internet
or from your Intranet.

Optica measures• Temperature• Relative humidity (% RH)• Dew/frost point (Td)
• Absolute humidity (m/v)• Mass mixing ratio (m/m)• Volume mixing ratio (v/v)• Wet bulb (Tw)• Enthalpy (h)• Water vapor pressure (e)• Pressure• Alarm relays• Analog outputs

Fundamental dew point measurement is a primarymeasurement used as a transfer standard for calibratingother humidity instruments and sensors. Chilled
mirrors are also the sensors of choice when process
and laboratory measurements call for high precision
without long term drift. Optica may be used with four,
fully interchangeable chilled mirror sensors to provide ameasurement range from -103°F to 185°F (-75°C to 85°C)
dew point with 0.36°F (0.2°C) or better accuracy. Inputs
for a 100 W RTD and silicon-based piezoresistive pressuretransducer ensure precision measurements, which are used
to convert the dew point to any metric, English or userdefined unit of humidity measurement.

Software
The Optica software is easy to navigate. Users selectreadout display, strip chart, analog output scale, digitalcommunications, self-diagnostics, cleaning and data
logging with intuitive pull-down menus. Setup values can besaved in memory and loaded anytime, either locally or fromanywhere via the Ethernet port.

The Optica simultaneously measures dew point, temperatureand pressure. The analyzer is equipped with programmable
math functions to produce custom units. In, exp +, -, x and /functions enable derived engineering units to be displayed,recorded and transmitted to data acquisition systems. The
analyzer input channel is a standard 4 to 20 mA/0 to 5 VDC
input, so the Optica can be connected to any type of processtransmitter and be configured to display engineering units.

“Plug and play” setup is easily accomplished with standard connectors for
power, sensor and analog outputs.

Chilled mirror sensors theory of operation
These chilled mirror hygrometers are used in standards andmetrology labs as well as in industrial applications where
precise and repeatable humidity measurement and control
is required. The inherent accuracy and long term stability
provides many advantages over other types of humidity
measurement technologies. Chilled mirrors fundamentallymeasure the dew or frost point temperature directly bycontrolling 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 polishedhexagonal rhodium, or platinum mirror attached tothermoelectric cooling module (TEC). The Optica analyzer’s
servo controller applies current to the TEC, which causes themirror to cool. The mirror is illuminated with a regulated Gas
emitter, which transmits light in the infrared spectrum. The
light reflected by the mirror is received by a photodetector.
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. The
Optica’s control system will modulate the amount of current
flowing though the TEC to maintain a temperature where therate of condensation and evaporation of water molecules
and the mass of water on the mirror is constant. The
resulting temperature of the mirror is then, fundamentallyby definition, equal to the dew or frost point temperature.
A precision four-wire platinum RTD imbedded in the mirror
measures the temperature. The accuracy of the dew point
measurement has been validated to an accuracy of ±0.36°F(±0.2°C) dew/frost point. The precision can also be enhanced
to ±0.27°F (±0.15°C) dew/frost point.
Dry bulb temperature is measured with a precise fourwire 100 W platinum RTD and pressure is measured with apiezoresistive silicon pressure transducer. The dew/frost
point and dry bulb RTD resistance signals are conditioned
and amplified by the Optica monitor to display and transmit
dew/frost point and temperature. The pressure sensor
transmits an amplified 4 to 20 mA signal that is powered by
the Optica. The cardinal measurements of dew/frost point,
dry bulb temperature and pressure are used to calculate
other humidity parameters such as relative humidity, wetbulb, mass mixing ratio, volumetric mixing ratio, absolute
humidity, enthalpy and water vapor pressure values using
psychometric equations.
The RTD sensor is embedded in the chilled mirror and nevercomes in contact with the process or test environment. The
wetted parts consist of the platinum or rhodium mirror, astainless steel or mylar vapor barrier and epoxy sealant. The
net result is drift-free humidity measurement designed tomaintain 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 withmoving air or be equipped with a sampling pump. The
optimum flow rate is 0.5 to 5 SCFH (0.25 to 2.5 L/min).

Our application engineers will discuss your applicationin detail and provide a recommendation for a complete
measurement system best suited to your needs.

Self cleaning and digital control
For environments where physical contaminants suchas dust, oil mist and pollen are present, the use of a samplingsystem 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 beetched or pitted by particulate, altering the light scatteringcharacteristics. Panametrics mirrors are field replaceable.
The standard rhodium mirror may be upgraded to platinumfor industrial applications.
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 value is transmitted) 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 heatinga 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 comparedagainst 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. (Distilled water is recommended as the
final cleaning agent.)
