OptiSonde ™ Chilled mirror hygrometer Key benefits Chilled mirror hygrometers are used in standards and metrology labs as well as in industrial applications where precise and repeatable humidity measurement and control are required. The inherent accuracy and long term stability provide many advantages over other types of humidity measurement technologies. • Compact and rugged design for easy installation and durability • Built-in data logger provides ability to record historical data • Sensor conveniently plugs into wall mount chassis for facility monitoring, eliminating the need to run cable • Sensors may be connected up to 91 m away via cable for remote monitoring • Displays and transmits in a variety of parameters, such as dew point, relative humidity, dry bulb, wet bulb, absolute humidity, volume ratio, and mass ratio, offering flexibility during operation • Digital (RS-232) interface for data integrity • Patented PACER® cycle automatically cleans mirror to ensure measurement integrity • PanaView™ software transfers data from the meter to a PC for additional storage and enables data to be viewed graphically • Easy to configure using the front panel for simple operation • Humidity measurements are traceable to National Institute of Standards and Traceability (NIST) Applications • Environmental test chambers • Engine test cells • Clean rooms • Air conditioning and heat exchange coil testing • 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. PACER cycle Before PACER cycle After PACER cycle Optical balance OP AMm Gas flow Power Precision four-wire PRTD Thermoelectric cooling module Rhodium or platinum mirror Light emitting diodes Photo detectors LED regulation Thermoelectric heat pump control 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.

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.
