概要
The CS300-QD, manufactured by Apogee, measures total sun and sky solar radiation for solar, agricultural, meteorological, and hydrological applications. Its spectral range of 360 to 1120 nanometers encompasses most of the short-wave radiation that reaches the Earth's surface. The CS300-QD supports continuous outdoor use.
続きを読む利点と特徴
- Compatible with most Campbell Scientific data loggers
- Designed for continuous, long-term, unattended operation in adverse conditions
- Measurement waveband of 360 to 1120 nm
- Dome-shaped head prevents water from accumulating on the sensor head

詳細
With this version of the CS300 pyranometer, the cable has a military style connector instead of pigtails for attachment to the RAWS-F Fire Weather Quick Deployment Station.
The CS300-QD uses a silicon photovoltaic detector mounted in a cosine-corrected head to provide solar radiation measurements. Its dome-shaped head prevents water from accumulating on the sensor head. To eliminate internal condensation, the sensor head is potted solid and the cable is shielded with a rugged Santoprene casing. The CS300 is calibrated against a Kipp & Zonen CM21 thermopile pyranometer to accurately measure sun plus sky radiation.

互換性
The military style connector attaches to the RAWS-F Fire Weather Quick Deployment Station, which has an on-board CR1000.
Sensor Mounts
Accurate measurements require the sensor to be leveled using a 18356 leveling fixture. This leveling fixture incorporates a bubble level and three adjusting screws. The 18356 mounts to a crossarm or a tripod or tower mast using the CM225 mounting stand. The CS300 should be mounted away from all obstructions and reflective surfaces that might adversely effect the measurement.
Data Logger Considerations
One differential analog input channel per probe is required.

すべてのセンサに異なるケーブル終端オプションがあるわけではありません。特定のセンサで利用可能なオプションは、センサ製品ページの注文情報エリアの 2 つの場所で確認できます。
モデル番号
ケーブル終端オプション リスト
センサが –ET、–ETM、–LC、–LQ、または –QD バージョンで提供されている場合、そのオプションが利用可能かどうかはセンサモデル番号に反映されます。たとえば、034B は 034B-ET、034B-ETM、034B-LC、034B-LQ、および 034B-QD として提供されています。その他のすべてのケーブル終端オプション (利用可能な場合) は、センサ製品ページの注文情報エリアの「ケーブル終端オプション」の下にリストされています。たとえば、034B-L 風力発電セットは、034B-L 製品ページの注文情報エリアに示されているように、–CWS、–PT、および –PW オプションで提供されています。
注意: 新しい製品が在庫に追加されると、通常は複数のモデル番号を作成するのではなく、1 つのセンサモデルの下に複数のケーブル終端オプションをリストします。たとえば、HC2S3-L には、HC2S3-LC モデルではなく、CS110 に接続するための –C ケーブル終端オプションがあります。

Most Campbell Scientific sensors are available as an –L, which indicates a user-specified cable length. If a sensor is listed as an –LX model (where “X” is some other character), that sensor’s cable has a user-specified length, but it terminates with a specific connector for a unique system:
- An –LC model has a user-specified cable length for connection to an ET107, CS110, or retired Metdata1.
- An –LQ model has a user-specified cable length for connection to a RAWS-P weather station.
If a sensor does not have an –L or other –LX designation after the main model number, the sensor has a set cable length. The cable length is listed at the end of the Description field in the product’s Ordering information. For example, the 034B-ET model has a description of “Met One Wind Set for ET Station, 67 inch Cable.” Products with a set cable length terminate, as a default, with pigtails.
If a cable terminates with a special connector for a unique system, the end of the model number designates which system. For example, the 034B-ET model designates the sensor as a 034B for an ET107 system.
- –ET models terminate with the connector for an ET107 weather station.
- –ETM models terminate with the connector for an ET107 weather station, but they also include a special system mounting, which is often convenient when purchasing a replacement part.
- –QD models terminate with the connector for a RAWS-F Quick Deployment Station.
- –PW models terminate with the connector for a PWENC or pre-wired system.
-
Many Campbell Scientific sensors are available with different cable termination options. These options include the following:
- The –PT (–PT w/Tinned Wires) option is the default option and does not display on the product line as the other options do. The cable terminates in pigtails that connect directly to a data logger.
- In the –C (–C w/ET/CS110 Connector) option, the cable terminates in a connector that attaches to a CS110 Electric Field Meter or an ET-series weather station.
- In the –CWS (–CWS w/CWS900 Connector) option, the cable terminates in a connector that attaches to a CWS900-series interface. Connection to a CWS900-series interface allows the sensor to be used in a wireless sensor network.
- In the –PW (–PW w/Pre-Wire Connector) option, the cable terminates in a connector that attaches to a prewired enclosure.
- In the –RQ (–RQ w/RAWS Connector) option, the cable terminates in a connector that attaches to a RAWS-P Permanent Remote Automated Weather Station.
Note: The availability of cable termination options varies by sensor. For example, sensors may have none, two, or several options to choose from. If a desired option is not listed for a specific sensor, contact Campbell Scientific for assistance.
