CMP10 Pyranomètre

CMP10 Pyranomètre

Le CMP10 est le pyranomètre étalon secondaire avec le meilleur rapport qualité-prix-performance du marché. Basé sur la technologie éprouvée du CMP 11, le CMP10 étend cette qualité pour les applications où l'entretien est difficile et / ou constitue une part importante du coût total de possession.

Le CMP10 possède une cartouche de séchage interne d’une durée d’au moins 10 ans, si le logement n'est pas ouvert. Cela réduit l’entretien de manière significative.

L'intervalle de nettoyage du dôme peut être étendue, et la qualité des mesures maximisée, en rajoutant au CMP10 l’unité de ventilation CVF4 récemment lancée.

Kipp & Zonen fournit pour chaque CMP10 une garantie de 5 ans en standard. Cette garantie s'applique à condition que le CMP10 soit utilisé uniquement dans des conditions atmosphériques, que le logement ne soit pas ouvert et que le câble Kipp & Zonen et son connecteur soient correctement mis en place.

FAQ

• What parameters or errors should we take into account if the source of light comes from a certain angle?

  • If the Pyranometer remains horizontal the error involved is the directional error listed in the Pyranometer brochure.

    For CMP 3 < 20 W/m²  and for CMP 22 < 5 W/m²

• Can I use a pyranometer under water?

  • The CMP series can also be used under water, the depth is limited to 1 meter and can only be used for short measurements.

    It is advisable not to keep the Pyranometer of the CMP series under water for longer than 30 minutes.

    The SP Lite2 pyranometer and the PQS 1 PAR Quantum Sensor can be used for a longer period under water, the depth is limited to 2 meters. Please also take  “breaking of light on the water surface” in consideration.

• If I use a pyranometer under water, can I connect a data logger to it ?

  • Yes, however the data logger needs to be placed on the surface (it is weather resistant, but cannot be lowered into the water).

• What is the calibration frequency of a pyranometer?

  • We advise to re-calibrate the Pyranometer every two years. 

    Is your question still unanswered? Contact Support
• What does spectral range of 310 – 2800 nm (50% points) mean?

  • The 50 % points are the wavelengths where the output of the instrument is 50 % reduced with 100 % input.

• What is the WMO standard for the pyranometers?

  •  

    	CMP 3	CMP 6	CMP 11	CMP 21	CMP 22
    WMO	Moderate quality	Good quality	High quality	High quality	High quality
    ISO	Spectrally Flat Class C	Spectrally Flat Class B	Spectrally Flat Class A	Secondary Standard	Secondary Standard

• What is the resolution of a pyranometer?

  • The instrument has an analog output, therefore the resolution is infinite. Every change is noticed, no matter how small it is.

    Is your question still unanswered? Contact Support
• What is the bandwidth of a pyranometer?

  • The bandwidth of most pyranometers is 285 to 2800 nm. This covers the full solar spectrum as shown below.

    There are some exceptions:

    • CMP22 has a bandwidth of 200-3600nm (Quartz glass )
    • SP Lite  has a bandwidth of 400-1100nm (silicon photo diode)
    • CMP3 has a bandwidth of 300-2800nm

• In our PV application the cable from the CMP 11 (50 meters) will go along other cables that come from the PV panels in which there is a DC voltage and around 100 Amps. Will these cables affect the measurement?

  • The disturbance on the cables on the CMP 11 is difficult to judge from a distance. A test would give the best criteria in this case.

    Simply cover the CMP 11 so it is fully dark (in box with cloth etc.) Log the data over a period that disturbance is expected, at least one day.

    If the data is zero no problem is to be expected.

• Do you have filters that can be used to verify spectral distribution over the following wave lengths? Ultraviolet - B 280-320 Ultraviolet - A 320-360 and 360-400 Visible 400-520, 520-640 and 640-800 Infrared 800-3000nm.

  • No, we do not have filters for any of our pyranometers. The only way to do this in a correct way is to use a filter dome. Otherwise the directional response would be affected.

• Is there a standard product that converts the pyranometer output signal to 0-5V or 0-2V?

  • The AMPBOX is the best solution.

    You will need a suitable PSU and a shunt resistor of 500 Ω to convert the current output (4..20mA) to a voltage output of 2-10V , or you will need a shunt resistor of 50 Ω to convert the current to a voltage output of 0.2-1V.

• What kind of pyranometer do you suggest for usage inside a greenhouse?

  • CMP 6 in combination with PQS1 PAR Quantum Sensor is advised.  CMP 6 for outside usage to measure Global solar radiation. PQS1 to measure  PAR radiation inside which is most sensitive for plants and crops.

• What type of pyranometer can I use for my fixed PV panels farm?

  • For this application the CMP10 and SMP10 are advised as they have an internal drying cartridge that will last for at least 10 years.

    Please note that the pyranometer needs to be mounted in the same angle (POA) as the PV panel. 

     

    

    For users that prefer the desiccant visible Kipp & Zonen offers the CMP11 and SMP11 with visible and user changeable desiccant.

• What type of pyranometer can I use for my solar concentrators farm?

  • None, solar concentrators are reflecting the direct solar radiation  to a concentrator and are tracking the sun. You will need a pyrheliometer on a sun tracker to measure direct solar radiation.

    Is your question still unanswered? Contact Support
• I would like to know what kind of output the CMP 6 Pyranometer has (analog or digital)? What voltage range do you have?

  • The CMP 6, as with all our solar radiometers based on thermopiles has a continuous small analoge voltage output. For CMP 6 an irradiance of 1 W/^m2 generates an output signal in the region of 5 to 15 micro-volts. We have additional solutions to increase this voltage.
