概要

The HC2S3-QD is a rugged, accurate temperature and humidity probe that is ideal for long-term, unattended applications. The probe uses an advanced capacitive sensor to measure relative humidity. The probe includes a filter to protect the sensor from dust and particles, for superior performance and reliability.

詳細

The HC2S3-QD comes with a polyethylene filter that protects its sensor from fine dust and particles and minimizes water absorption and retention. Alternatively, a Teflon filter is available for marine environments. The response time is slower when using the Teflon filter.

すべて展開すべて折りたたむ

  1. 特定のセンサで利用可能なケーブル終端オプションはどこに記載されていますか?

    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。

  2. What are the different cable length choices available for Campbell Scientific sensors?

    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.
  3. What are the different cable termination options available for Campbell Scientific sensors?

    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.
