1, the basic principle of measuring the wind speed is the use of this instrument calorimetric principle wind. Measuring wind speed sensitive parts of an electronic anemometer hot bulb diameter of about 0.8mm, it is also known as hot bulb anemometer 2, the basic principle of temperature measurement: The instrument used precision thermistor temperature measurement as the sensing element. Use the thermistor resistance changes with temperature characteristics of measuring temperature 3, the measurement of relative humidity Rationale: The instrument used by the US company Honeywell as a measurement of relative humidity sensor, using its output varies with the relative humidity of the characteristics to measuring the relative humidity CN60M / ZRQF-F30 is a smart anemometer to measure wind speed anemometer for basic functions, increasing the calculation amount of wind handheld anemometer to measure a variety of functions such as temperature and relative humidity, a combination of a series of instruments. It is a portable, with intelligent, versatile, low wind speed measuring anemometer basic instrument manufacturers in the heating, ventilation, air conditioning, environmental protection, energy monitoring, meteorology, agriculture, refrigerating, drying, labor health survey, clean workshop, textile, and other aspects of the various wind speed laboratory wide range of uses. Thermal velocity probe built-in temperature and humidity sensors, simultaneous measurement of temperature and humidity, ventilation ducts and other applicable measurements. Thus, wind speed, air flow, air temperature and air humidity are measured in the same process. 1, measurement of the average flow velocity and direction. 2, measuring the speed of its spectrum to pulsating flow. 3, measuring turbulent Reynolds stresses and two speed correlation, time correlation. 4, the measurement of wall shear stress (usually placed flush with the wall using the hot-film probes conducted similar principles and hotline speed). 5, measuring fluid temperature (measured in advance probe resistance curve with fluid temperature, and then you can determine the temperature of the measured resistance probe electronic anemometer, Jinke instrumentation (certified), anemometer by Qingdao Branch Instrumentation Limited.
