Sensing element for measuring the wind speed with a diameter of about 0.8mm of spherical element. Is a portable, intelligent, versatile, low wind speed measuring basic instruments. Electric hot bulb anemometer anemometer 1. Construction principle is a low wind instruments can be measured, and its measurement range is 0.05-10m / s. Anemometer is composed of hot bulb measuring rod probe and measuring instruments in two parts. The probe has a diameter of 0.6mm glass beads, glass beads wound heating wire with chrome ring and fell two series of thermocouples inside the ball. Thermocouple is connected to the cold end uses copper pillar phosphorus Qingdao anemometer, directly exposed to the gas stream. When the current through the heating coil certain size, glass balls temperature. Elevated degree of versatility and speed related Qingdao wind speed scale, the extent of a large increase in wind speed hours; otherwise supply Taiwan wind speed scale, to a lesser extent elevated. Elevated levels of the size of the thermocouple is indicated on the meter. According to the meter readings, check the calibration curve, you can find out the wind speed (m / s).
