摘要： A liquid-level detection device detects a level of a surface of liquid stored in a container. The liquid-level detection device includes: a float that floats on the surface of liquid; a rotatable body that rotates due to a upward or downward displacement of the float and includes a rotation contact part; a supporting body that rotatably supports the rotatable body and includes a supporting contact part which is located on a rotational track of the rotation contact part to restrict the rotation of the rotatable body in a specified direction by contact between the supporting contact part and the rotation contact part; and an attachment member that is attached to the supporting body and includes an attachment contact part which makes contact with the rotatable body rotating in the specified direction to prevent the contact of the rotation contact part with the supporting contact part.

摘要： A liquid level transducer includes a mounting head for connection to the wall of a tank and a housing extending into the tank from the mounting head. A float rod is pivotally connected to the housing and a float is connected to the float rod for pivotal movement upon a change of liquid level in the tank. A proximal end of the float rod is connected to an actuator portion and constrained for pivotal movement about two parallel axes so that the actuator portion moves in a linear direction with respect to the housing. The interior of the housing includes a sensor assembly responsive to the linear movement of the actuator portion to thereby determine the level of liquid within the tank.

摘要： Provided is a liquid level detection device which is configured so that an arm can be easily mounted to a holder after the holder is pivotably mounted using a cover and a main body portion. An end of a float arm is bent at a substantially right angle, and the end side of the float arm is defined as a first end portion. The portion of the float arm which is located closer to the center of the float arm than the first end portion is defined as a second end portion. A first arm mounting portion to which the first end portion is affixed and second arm mounting portions to which the second end portion is affixed are provided to a holder. A stopper for restricting the pivot range of the holder is provided to a main body portion. A first stopper which comes into contact with the stopper is provided to the holder. The first arm mounting portion and the first stopper are provided on a line passing through the pivot axis of the holder and perpendicular to the pivot axis.

摘要： In the case of a filling level sensor (1) for detecting a fuel filling level in a fuel tank (2), a lever arm (7) which secures a float (6) has a guide part (14). The guide part (14) interacts with an installation opening (3) in the fuel tank (2) and deflects the lever arm (7) in a designated direction. This avoids the filling level sensor (1) being damaged during installation in the fuel tank (2).
