Environmental measurement sensors

//Environmental measurement sensors

Atmospheric pressures

Compared to other meteorological parameters, the atmospheric pressure sensors are not installed in the outdoor but in the same environmental system as the indoor and outdoor pressure is the same. The basic model DQA240 is installed in the same datalogger offering a low level output and a low electric consumption. The models DQA250 and DQA223 for wall mounting incorporate additional characteristics like thermal compensation or height correction (the atmospheric pressure decreases with the height).

Pluviometry

The rain is measured by pluviómetros de balancín. The collected area of 324 cm2(203 mm of diameter) is compliance with the guidelines of WMO. El balancín interior (recipiente basculante) fills and empties generating a pulse every 0.1 or 0.2 mm of precipitation (lit / m2) that will be used to measure the intensity and accumulated rainfall. The pluviometers can be installed at the end of the mast, on the side or based in the ground. he sensors may be heated for measuring the solid precipitation (snow or hail). For those cases we offer DQL011 model that measures the level on [...]

Evaporation

They are a fundamental element in agriculture research and in en las mediciones de cuencas hídricas. Automatic evaporímetros are a complete system that includes the following elements. Evaporation container DYI010 of 1143 m2 surface built in stainless steel with A class according to WMO. Isolation base DYI011/ DYI013 for the isolation of the container from the ground. Level sensor DQC102, 200 mm with high accuracy and resolution. Auxiliary elements. Like connection cables, valves for automatic filling from the tank or the control that performs the measurement, calculation, data acquisition and filling control.

Radiación

Global radiation or piranómetro Measurement of the solar radiation in all of its spectrum of 305nm 2800 nm. Measurement capacity from0 to 2000 W/m2. We offer different accuracies depending on the WMO (ISO 9060) class 1 (DPA153) or class 2 (DPA053). The output signal may be low level (mVdc) for direct connection with meteorological datalogger, or amplified with universal 4-20 mA and 0 to5 Vdc. Net radiation It measures the net radiation base din the difference of measurements of radiation temperatures received from the sun and reflected or emitted by the ground. The DPA 240 model measures a radiation up [...]

Gas concentration

The information can be extended in the GASES where gas types and measures are explained.

Visibility

The visibility sensor DPA 305 with measuring range of 2km is designed to detect fog in roads and tunnels. It has both digital and analogic outputs, and relays for external device. The sensor can be integrated in smart transport systems and is used to automate warning signals when changing visibility conditions. Water particle analysis DPA311 with different shapes in air and fog, rain, and snow. Can measure the visibility, and type of rainfall including intensity and accumulation.
