Abstract
The utility model relates to an anti-corrosion humiture sensor comprising a metal protective screening, a fiber cloth, an insulating spacer, a barrel-shaped cutting sleeve, a metal casing barrel, a magnet, a clapboard, a rubber seal ring, a micro tension spring, a solenoid, a humiture sensing element, a fixed substrate, a microbattery, a wire, a micro resistance and a quadded cable. The utility model leads to the balance relationship of the acting force between the micro tension spring, the magnet and the electromagnetic field so as to achieve the aim for drawing the internal sealing device for opening or plugging the transmission channel. During the test, the inner circuit is switched on to form a current loop, and the solenoid produces the interaction between the electromagnetic field and the magnet so as to draw the internal sealing device to open the transmission channel so that the internal and the external materials (water vapour) can be moved for exchanging. When the test is completed, the electromagnetic field disappears due to the disconnection of the circuit, and the micro tension spring draws the sealing device for plugging the transmission channel, thus being able to avoid that the humiture sensor element is damaged and the accuracy is reduced due to the contact with the corrosive materials for a long time.
