概览

The ClimaVUE™50 is an affordable all-in-one meteorological sensor that fulfills your common weather monitoring needs with simplicity, when paired with any of Campbell Scientific's highly flexible and scalable data collection platforms. This sensor uses SDI-12 to report air temperature, relative humidity, vapor pressure, baro­metric pressure, wind (speed, gust, and direction), solar radiation, precipitation, and lightning strike (count and distance). It does this with no moving parts, while consuming little power. A built-in tilt sensor assures long-term data integrity. This diverse product is great for quick deployment, for remote locations, for large networks, as part of a more complex system, or if you just need something simple.

优势与特点

技术说明

Sensors

All sensors are integrated into a single, small form-factor unit, requiring minimal installation effort. With a robust, no-moving-parts design that prevents errors because of wear or fouling, the ClimaVUE™50 is ideal for long-term, remote installations.

Pyranometer

Solar radiation is measured by a pyranometer that is integrated into the lip of the rain gage funnel at the top of the ClimaVUE™50. The miniature pyranometer uses a silicon-cell sensor to measure the total incoming (direct and diffuse) solar radiation. Silicon-cell sensors have excellent response time to changing radiation conditions and acceptable sensitivity across the solar spectrum, which make them well-suited for use on the ClimaVUE™50.

A carefully developed cosine-correcting head ensures accurate readings regardless of sun angle, while the painstakingly researched optical filter material balances cost and performance to ensure the silicon-cell provides the ClimaVUE™50 with good accuracy regardless of temperature or sensor age. 

Anemometer

The space underneath the rain gage is where the ClimaVUE™50 measures wind speed. Ultrasonic signals emitted from transducers at right angles to each other bounce off the porous sintered glass plate and back up to the opposite sensor. The speed of sound is affected by the wind, and the wind speed is calculated by measuring differences in the time it takes for sound to travel from the transmitters to the receivers.

Temperature Sensor

The ClimaVUE™50 temperature measurement is made in the center of the anemometer area where a small stainless-steel needle containing a tiny temperature sensor (thermistor) extends from the middle of the four sonic transducers in the center of the anemometer.

Unlike most air temperature measurements, the temperature sensor is not covered with louvered plates to protect it from solar heating. Instead, it sits in open air, susceptible to solar heating of the instrument body. However, the ClimaVUE™50 accurately corrects the measured air temperature because solar radiation and the wind speed are known. These two are the main variables that determine the error between measured air temperature and the actual air temperature. An energy balance equation is then used to calculate what the actual temperature should be to an accuracy of ±0.6°C. 

For more information, see the "ClimaVUE™50—Correction of air temperature measurements from a radiation-exposed sensor" technical paper.

Relative Humidity Sensor

The relative humidity sensor on the ClimaVUE™50 is located behind the circular Teflon™ screen close to the sonic transducers. The Teflon screen protects the sensor from liquid water and dust while allowing water vapor to freely pass to the sensor. The ClimaVUE™50 measures relative humidity and temperature and computes vapor pressure.

Drip Counter Rain Gage

The ClimaVUE™50 contains a 9.31 cm (3.67 in.) diameter rain-collection funnel. A spring in the funnel acts as a filter to keep out large particles while allowing enough flow so water does not back up. Rain collected by the funnel exits the funnel through a precision flared hole that forms the rain into drops of a known size. The falling drops hit and momentarily bridge the gap between two gold pins, creating an electrical pulse.  

The ClimaVUE™50 counts the pulses (drops) and calculates the water volume. As the rain intensity increases, the drops become smaller, but the ClimaVUE™50 firmware contains an algorithm to automatically compensate for drop size as the rain increases.

Note: This non-heated sensor is not suitable for solid precipitation measurements or riming environments.

Tilt Sensor

The ClimaVUE™50 is also equipped with a tilt sensor. The primary use of the tilt sensor data is to ensure the ClimaVUE™50 remains level at all times. Regularly check X and Y tilt data to ensure the ClimaVUE™50 is level; if it has tilted, return to the site and level again. Three degrees off level can cause errors in the rain and solar radiation measurements. Although this sensor's readings may be used to level the instrument during installation, it is much easier to use the small bubble level on the bottom of the anemometer plate.

Mounting

The ClimaVUE™50 includes a V-bolt for mounting to a pipe with a nominal outer diameter of 31.8 to 50.8 mm (1.25 to 2.0 in.). This allows the sensor to mount directly to a tripod mast or CM300-series mounting pole, or to a crossarm using the 17387 mounting pipe kit.

常见问题解答

ClimaVUE50: 9

展开全部收起全部

  1. The average current drain for the ClimaVue™50 during the quiescent state and routine 10 s wind measurement is on the order of 300 microAmps.

  2. The ClimaVue™50 is a microclimate sensor, so you should position it to be representative of the climate relevant to the research questions you are asking. FAO56 gives specific guidelines to the positioning and field size of sensors. If you intend to use the sensor for reference ET, follow those guidelines.Refer to the following: http://www.fao.org/docrep/X0490E/X0490E00.htm.

  3. The SDI-12 bus is capable of having at least 10 sensors connected to it, each with 200 feet of cable. With fewer sensors, longer cable lengths are possible.

  4. The ClimaVue™50 mounting type can be a meteorological stand, pole in cement, or tripod: 31.8 to 50.8 mm, 1.25 to 2.0 in. diameter. The ClimaVue™50 is fitted with a V-bolt, allowing it to be mounted on top of most posts, poles, tripods, etc. Use a wrench to tighten the bolts, securing the ClimaVue™50 flat and tight against the top of the stand.

  5. The ClimaVue™50 collects all the information necessary to correct for absorbed radiation using an energy balance approach.

  6. We do not have a heated version of the ClimaVue™50 at this time. The model to correct the air temperature is based on the energy balance and should be good in all situations in which the radiation and wind sensors can collect reliable data; however, unintentional burial in snow and ice may impede the function of both. The ClimaVue™50 will not be a universally great fit for all climates. If the winter precipitation is critical for your study, other instruments will be necessary.

  7. The ClimaVue™50 does need to be powered continuously to make the routine wind measurements (every 10 seconds) that are combined to give the wind speed and direction. If you only power up and quickly grab a measurement, those wind speed and direction measurements will be of little value, given the inherently variable nature of wind. Campbell Scientific highly recommends that you power the ClimaVue™50 instruments continuously for reliable wind measurement. The average current drain for the ClimaVue™50 during the quiescent state and routine 10 s wind measurement is on the order of 300 microAmps, so battery drain from continuous power should be minimal.

  8. See the maintenance section of the manual for recommendations.

  9. 不是每一种传感器都有不同的线缆尾端选项。通过查找传感器产品页面的订购栏 (Ordering tab) 中的两个位置,可以检查某种特定传感器的可用的线缆尾端选项:

    • 产品型号
    • 线缆尾端选项列表

    如果传感器以 –ET, –ETM, –LC, –LQ, 或 –QD 等版本的型号供应,那么线缆尾端选项已经反映在该传感器的产品型号中。例如,034B 以 034B-ET, 034B-ETM, 034B-LC, 034B-LQ, 和 034B-QD 等型号供应。

    所有其它的线缆尾端选项,如果可用,会列在该传感器产品页面的订购栏 (Ordering tab) 中的线缆尾端选项 (“Cable Termination Options) 区域。例如,034B-L 风速风向传感器具有 –CWS, –PT, 和 –PW 等线缆尾端选项,显示在 034B-L 产品页面的 订购栏 (Ordering tab) 位置。

    注: 当更新的产品添加到我们的库存中时,一般来说,我们会在单个传感器的产品型号下面列出多种线缆尾端选项,而不是创建多个产品型号。例如,HC2S3-L 具有 –C 线缆尾端选项用于连接到 CS110,而我们并没有使用 HC2S3-LC 产品型号。
