ABSTRACT:
In a liquid level indicator, a liquid level sensor (e.g. thermistor) is attached to a lower end of a sensor shaft fixed to an indicator frame. In the conventional way, the sensor shaft is directly fixed by screws to the frame, so that the sensor shaft is apt to be loosened, resulting in unreliable and inaccurate liquid level indicator or liquid level alarm indication. To overcome these problems, the sensor shaft is fixed to the frame by a single screw to restrict sensor shaft movement in the Z direction and further supported by at least one first and second sensor shaft restriction members to restrict sensor shaft movement in the X-Y directions. The restriction members are U-shaped support members or a shaft bent end insertion hole molded together with the frame or metal parts welded to the frame.
