概要
The CS215 is a temperature and relative humidity probe that uses a Swiss-made digital humidity and temperature element that makes accurate and stable measurements. The element is based on Sensirion's CMOSens technology, which has been tested for more than two years in alpine conditions. The CS215 outputs an SDI-12 signal that is measurable by most Campbell Scientific data loggers.
続きを読む利点と特徴
- Accurate and stable measurements
- Field changeable element allows on-site recalibration
- Each sensor element is individually calibrated so no further adjustment of the probe is required
- Low power consumption
- Digital SDI-12 output
- Wide operating range

詳細
The CS215 uses the Sensirion SHT75, a combined relative humidity and temperature element, to provide accurate, stable measurements. The Sensirion SHT75 element is field-replaceable, eliminating the downtime typically required for the recalibration process. The CS215 outputs an SDI-12 signal that's measurable by many Campbell Scientific data loggers.
The CS215 should be housed in a solar radiation shield—typically the 41303-5A. The 41303-5A 6-plate naturally aspirated shield attaches to a mast, crossarm, or tower leg.

Sensor Mounts
When exposed to sunlight, the CS215 must be housed in a 41303-5A radiation shield. To attach the 41303-5A to a CM202, CM204, or CM206 crossarm, place the 41303-5A’s U-bolt in the bottom holes. To attach the radiation shield directly to a tripod mast, tower mast, or tower leg, place the U-bolt in the side holes.
The CS215-L Temperature and RH sensor can also be housed in the 43502 if a special adapter from R. M. Young (R. M. Young pn 43537) is used.

-
Relative humidity (RH) from the probe is capped at 100%. If readings of 100% occur during drier conditions, it is possible that the chip, the entire sensor, or both have associated issues. Repair, maintenance, or replacement is likely needed. Contact Campbell Scientific for assistance.
-
Yes. This is pn 18142.
-
If the values are not within the published range of the sensor, there are several things to check:
- If the yellow cap has not already been removed, remove it.
- Verify that the program is correct without additional multipliers or offsets.
- Ensure that the filter and radiation shield are clean so that air can freely flow into and past the sensor.
- If the first value returned in the array is NAN, this is usually an indication that the data logger is unable to communicate with the sensor. This could be caused by a power issue, an incorrect SDI-12 address, one or more disconnected wires, or a broken sensor.
-
Yes, using pn 18144, Replacement RH and Temperature Element and Filter Cap for CS215. However, Campbell Scientific recommends taking the necessary precautions associated with changing electronics in the field. As this is a relatively small chip, it is not recommended to replace the chip during stormy weather or without having some type of collection container placed underneath in case the chip is accidentally dropped.
For assistance replacing the chip, refer to the “Maintenance and Calibration” section of the instruction manual.
-
Yes. This can be purchased from Campbell Scientific (pn 18144, Replacement RH and Temperature Element and Filter Cap for CS215). This chip replaces both the temperature and RH humidity sensing element.
-
No. The sensor cannot be calibrated, but Campbell Scientific can perform a calibration verification that includes multiple points (temperature and relative humidity). Campbell Scientific recommends using three points for RH (10%, 50%, and 90%) at one temperature (25 degrees Celsius), as well as an additional temperature point. This verification process has an initial setup charge and an additional per-point charge. Campbell Scientific sends a document indicating the values tested to with the accompanying measurement from the associated sensor.
-
Refer to the “Maintenance and Calibration” section of the instruction manual.
-
The most significant difference is that the CS215-L has an SDI-12 output and that the HMP60-L has a voltage output. Additional differences are outlined in the “Air Temperature & Relative Humidity” brochure, which compares all of the Campbell Scientific temperature and relative humidity sensors.

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.
