Abstract

The invention relates to a sensing head of an omni-directional wind speed sensor. The sensing head is characterized by comprising a sensing head shell (1), a heating element support (2), a heating element (3), a heat conductor (4), a temperature sensor (5), a base and a cable (7); the heating element support (2) and the heating element (3) are arranged in the sensing head shell (1); the heating element (3) is arranged on the heating element support (2); the temperature sensor (5) is arranged on the heat conductor (4); a slot is arranged on the sensing head shell (1); an installation groove is arranged on the end surface of the sensing head shell (1) in the slot; the heat conductor (4) is arranged in the installation groove; the sensing head shell (1) is installed on the base (6); and the axial direction of the sensing head shell (1) and the bottom of the base (6) are provided with installation holes of the cable (7). The sensing head can be used for measuring omni-directional wind speed, improving environment tolerability of the sensor and prolonging the service life of the sensor.

Description

technical field [0001] The device can be widely used in measuring wind speed and wind direction in nature. Background technique [0002] At present, there are two types of crosswind sensor sensitive heads for measuring wind speed and direction, one is the impeller type and the other is the hot wire type. The impeller type sensor has the disadvantages of large moment of inertia and sensitivity to the use environment; Sputtering platinum resistors on the substrate, self-heating method, due to the limitation of structure and process, it is easy to cause the coating film to peel off from the ceramic carrier, thus affecting the measurement accuracy and poor environmental adaptability; at the same time, the above two sensors are both horizontal wind sensors, which cannot Measure wind speed in all directions. Contents of the invention [0003] The purpose of the present invention is to solve the problems of measuring the wind speed in all wind directions while improving the envi...
