LW110 Lightning Warning System
利用できるサービス

概要

The LW110 provides continuous monitoring of the local electric field and triggers warnings when there is the potential for lightning. Because warnings are based on measurements of electric field, instead of prior strikes, the system can detect lightning danger, even when no other strikes have occurred.

By measuring the electric field at your location, the LW110 can be relied upon to remove the guesswork from critical decisions: when to seek shelter as a storm approaches, and when it’s safe to resume activities as a storm passes.

The LW110 is customizable, allowing you to add a lightning strike detector, meteorological sensors, and various communication, power, and mounting options.

利点と特徴

  • First strike warning--senses potential for lightning
  • "All clear" notices when lightning threat has passed
  • Up to 7 mile detection radius
  • Visual and audible alarms
  • PC, web, and email alarms when communication is added
  • Optional SG000 detects strikes up to 20 mile radius and can be added to create a complete lightning-threat measurement and analysis system
  • Optional meteorological sensors for expanded weather monitoring and logging
  • Rugged construction
  • Low power consumption
  • Low maintenance—extensive diagnostics let you know when maintenance is needed

IMPORTANT!
The CS110 and an embedded CR1000M datalogger module (ordered as pn 18292) are required for every LW110 purchased; see Common Accessories in ordering information.

Generally, the CS110 should be run with the latest released CR1000 operating system (OS) available via "Support" on this website. However, CR1000 OS version 27.05 should NOT be downloaded to standard CS110s. OS version 27.05 was built to accommodate the ~40,000 v/m efields measured on ocean buoys. The special OS also requires a capacitor change on the CS110 panel board.

The CS110 should not be run with OS 28 (CR1000.Std.28.obj). A bug in OS 28 prevents changing the setup "Constants" via the keyboard or the terminal emulator.

よくある質問

LW110に関するよくある質問の数: 6

すべて展開すべて折りたたむ

  1. The CS110 and the tower should be positioned away from each other a distance of three times the tower’s height.

    If the radio signal is strong enough, the SG000 may pick it up as one of the two components the SG000 measures to detect lightning. If this signal coincides with a light flash from a windshield or headlight, it could generate a false strike signal. Also, constant bombardment of the SG000 by sufficiently strong RF signals will pull the sensor out of its quiescent state, affecting its current drain. This will eventually degrade the battery and shorten its expected four-year lifespan.

  2. To simulate a lightning strike to the SG000, use a camera flash to flash the glass bulb from a distance of 5.08 to 7.62 cm (2 to 3 in.). Note: A flash from a cell phone usually isn't large enough to simulate a lightning strike. 

    To simulate high electric fields on the CS110, run a comb through your hair and hold it a distance of 2.54 to 5.98 cm (1 to 2 in.) from the shutter of the CS110. Other items such as plastic bags or balloons, or fur on glass, can be used as well.

  3. The FC100 is required to communicate with the SG000 Strike Guard Lightning Sensor. The SG000 is an option for the CS110 Electric Field Sensor and the LW110 Lightning Warning System.
  4. 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。

  5. 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.
  6. 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.
