Sensor

Using the linear relationship between the internal pressure thrust of the metal bellows and the stiffness force generated when the bellows is deformed, the conversion between different dimensions of pressure/force/displacement can be realized, so as to realize a certain measurement function, a certain pressure automatic control and other functions.

Using the linear relationship between the internal pressure thrust of the metal bellows and the stiffness force generated when the bellows is deformed, the conversion between different dimensions of pressure/force/displacement can be realized, so as to realize a certain measurement function, a certain pressure automatic control and other functions.

In order to make good use of the above-mentioned special functions of the metal bellows, we can actively cooperate with the customer's design plan to provide high-precision sensitive bellows.

Typical case of bellows as a sensor application:

◎ An actuator in the space capsule uses bellows to achieve pressure self-balancing.

◎ safety valve through the bellows formed by the medium pressure thrust, back pressure thrust, bellows stiffness force vector synthesis to achieve control safety valve open/close.

◎ By adjusting the pressure in the bellows to achieve the end face sealing force adjustable.
