Hot bulb anemometer principle is the use of calorimetric measuring wind velocity. Sensor for measuring the wind speed with a diameter of about 0.8mm of spherical element. Is a portable, intelligent, multi-functional, low wind speed measuring basic instruments. Electric hot bulb anemometer anemometer principle 1. Construction is a low wind instrument can measure, which measures the range of 0.05-10m / s. Anemometer is composed of hot bulb spindle probe and measuring instruments in two parts. The probe has a diameter of 0.6mm glass beads, glass balls wound down chrome heated wire loop and two series of thermocouples inside the ball. Thermocouple cold end is connected to the phosphor bronze pillar, directly exposed to the gas stream. When the current size of certain low-cost sales through the heating coil anemometer, glass spheres temperature. An elevated level and wind speed anemometer, wind speed h elevated large extent; on the contrary, to a lesser extent increased. Elevated levels of the size of the thermocouple is indicated on the meter. According reading purposes and principles of the anemometer meter, check the calibration curve, you can find out the wind speed (m / s).
