The MS-802 highest class ISO Sec-ondary Standard is used for the most demanding applications in PV, Meteorology, field research and solar radiation monitoring of global, tilted and diffuse irradiance.Those are all thermopile type pyranometers which have a 180 degree field-of-view for measuring the hemispheric solar radiation with a cosine-weighting function. Depending on the model either one or two transparent glass domes protect the sensor efficiently from thermal effects.Measurement PrincipleMS-802 - ISO 9060 “Secondary Standard”Thermopile, which has a flat spectral response at all wavelengths, is integrated as a sensor. Thermopiles generate electricity by thermo-electric effect, which is caused by the tempera-ture difference between hot and cold junctions. Solar irradiance is obtained by measuring voltage from the thermopile sensor.Glass dome to reject infrared radiation of wavelength above 3?m is necessary for thermopile-type sensors. Otherwise, these sensors would detect all infrared radiation as well as solar radiation. Double-dome construction is designed to eliminate secondary thermal radiation effects caused by cooling of the outer dome.MS-410 - ISO 9060 “First Class”The MS-410 is perfectly suited for sampling 10-minute averages of the solar radiative flux in horizontal or tilted configurations. The flat sensor surface, coated with a special, highly ab-sorbing black paint, is protected by two transparent hemispheric glass domes.MS-410 has a 180° field-of-view for measuring the hemispheric solar radiation with a cosine-weighting function. The two transparent glass domes protect the sensor efficiently from nega-tive thermal effects. MS-410 has a practical light-weight anodized aluminium housing and a highly efficient sensor coating.MS-602 - ISO 9060 “Second Class”MS-602 detector consists of a special polymer film with the advantage of having very small temperature response and long-term durability. Thermopile detects temperature difference between the center- and the peripherally mounted hot and cold junctions, respectively. Hot and cold junctions are positioned radially. Detector is coated by special black paint, which has independent wavelength.Calculation of IrradianceE = U / SE [W/m²] = IrradianceU [µV] = Output VoltageS [µV/W/m²] = SensitivityAmmonit Measurement GmbHWrangelstrasse 100, D-10997 Berlin, GermanyT: +49 30 6003188-0, E: info@ammonit.commeasuring wind powerwww.ammonit.comEKO Pyranometers (MS-802 / -410 / -602) S64120 / S64130 / S64110SchematicMS-802 MS-410MS-610*Length of fixed leg is indicated*Length of fixed leg is indicatedpage 2/380mm80mm60mm66mm66mm45mm*16mm*16mm>0mm160mm160mm78mm66mm110mm107mmAmmonit Measurement GmbHWrangelstrasse 100, D-10997 Berlin, GermanyT: +49 30 6003188-0, E: info@ammonit.commeasuring wind powerwww.ammonit.comEKO Pyranometers (MS-802 / -410 / -602) S64120 / S64130 / S64110SpecificationsPyranometer MS-802 Pyranometer MS-410 Pyranometer MS-602Order No. S64120 S64130 S64110Classification ISO 9060 Secondary StandardISO 9060 First ClassISO 9060 Second ClassSensitivity ~ 7 µV/W/m2(see calibration protocol)~ 7 µV/W/m2(see calibration protocol)~ 7 µV/W/m2(see calibration protocol)Spectral range (50% points) 285 ... 2800 nm 285 ... 2800 nm 285 ... 2800 nmMax. irradiance 2000 W/m2 2000 W/m² 2000 W/m²Typical signal output for atmospheric applications 0 ... 10 mV 0 ... 10 mV 0 ... 10 mVResponse time (95%) <5s <18s <17sZero offset(a) thermal radiation (200 W/m²)(b) temperature change (5k/hr)+6W/m²<2 W/m²+6 W/m²<2 W/m²+10 W/m²<6 W/m²Non-linearity (0 ... 1000 W/m²) <0.2% <1% <1.5%Temperature dependence of sensitivity (-10 ... +40°C) ±1% ±2% ±2%Operating temperature -40 ... +80 °C -40 ... +80 °C -40 ... +80 °CCable length 10m 10m 10mDelivery includes calibration certificate.Sensor ConnectionMS-802Sensor Plug PIN No.Wire Colour(EKO)Meteo-40 Analog VoltageSolar irradiance Output voltage1 white (+) Ax2 black (-) Bxshield Main Ground (GND)MS-410 / MS-602Sensor Plug M12PIN No.Wire Colour(EKO)Meteo-40 Analog VoltageSolar irradiance Output voltage1 white (+) Ax2 black (-) Bx3 not connected not connected4 not connected not connectedshield Main Ground (GND)Last Modification: 28 March 2013 page 3/3
