Abstract
The invention relates to a differential pressure type wind speed transmitter. Two wind pressure adapting pipes are arranged inside a vacuum pumping pipe in parallel, an electric pressure sensing component is mounted in the vacuum pumping pipe, acrylonitrile butadiene styrene (ABS) plastic plugs capable of sliding vertically up and down are arranged in the wind pressure adapting pipes located inside the vacuum pumping pipe, T-shaped connecting bodies facing the central axis of the vacuum pumping pipe are arranged on side walls of the ABS plastic plugs, and the wind pressure adapting pipes located at the lower part of the ABS plastic plugs are filled with oxygen. The influence of wind pressure on the ABS plastic plugs is fed back to a traditional air pressure difference detection device and is further fed back to the distance between capacitor plates, so that the voltage change between the capacitor plates is influenced; another data acquisition way is provided and has the higher reference value, meanwhile, the sealed vacuum pumping pipe can reduce the influence of the temperature as much as possible, the stability of measurement results is improved, the density of the oxygen used for filling is relatively low, and the displacement range can be larger after the wind pressure is fed back to the ABS plastic plugs.
