Multi-Instrument Weather

Structure shown in Figure 3. F = Department of the sensor has a heating wire around the p - N junction, outside covered with resin, made of spherical, to feel the wind. Here a p - N junction with the above a the same characteristics, but there is no heating coil,[link widoczny dla zalogowanych], temperature changes as a tadpole {'s compensation. Through the heating coil in the constant current, probe temperature changes as wind speed changes in Korea. Sulfone is specified speed rotating rod in our laboratory and special within the air duct, the calibration in the 01 ~ l5m / s between the accuracy within ± 3% or less, the direction of less than 5%. * Third, the shape of the instrument instrument shown in Figure 4 The right side of the shelf from left to right with the wind speed, air temperature, temperature, radiant heat four sensors; the left side of the instrument host, the front fitted with LED light tube display, keyboard, and switch on the back with mini-printer. The instrument has taken a 51-type single-chip computer MCS real time control. The sensor output signal by the preamplifier and the V / F conversion, by the 8031CPu at line processing and computing, and finally by the LED display,[link widoczny dla zalogowanych], and mini-printer to print the results of the work of the state apparatus with the keyboard settings can also be called with the press. To select a parameter measured. In the absence of radiant heat, the baby's temperature is a real show temperature II. However, where radiant heat when the temperature is slightly higher than the air show the real temperature. * '38 * Temperature display in two ways, namely, temperature, dew point temperature and relative. More drama because of the wind speed, the degree of change is a problem worthy of attention, so the instrument can display the instantaneous wind speed and average wind speed at different times. Six surface radiation heat sensors, the instrument can be displayed in addition to the orientation direction of the average of six radiation temperature, but also shows the average radiation temperature of the six directional mean, that is, the average radiation temperature ring lay. Demand in the environment with black bulb thermometer, F are radiant temperature, air temperature and wind speed measured at the same time still need. Then we calculate the average radiation temperature environment, more complex procedures, the reaction is very slow. The instrument can be replaced by juice black globe temperature, m and responsive. Symmetric directional radiation temperature when the comfort of the human body a great impact, ISO7730 also provides asymmetric temperature limits. This instrument displays, the left and right,[link widoczny dla zalogowanych], and after three asymmetric radiant temperature. Figure 4 Multi-meter contour map the role of weather temperature is also an important indicator. When the ambient radiation temperature and air temperature is not far off, the effect of temperature is the average of them, the instrument can also be displayed. Fourth, the conclusion of the developed multi-instrument can display and print weather temperature,[link widoczny dla zalogowanych], humidity, wind speed, radiation,[link widoczny dla zalogowanych], temperature, temperature of an argument etc., well enough accuracy for the analysis of indoor weather conditions are very convenient. The field with the Danish Indoor Climate Brual & aer1213 analyzer comparison test between the two very basic performance. However, some of the features in the range and different. We developed the instrument can replace 1213 model equipment, and more appropriate sets of conditions, to facilitate application.
