1. A transducer for determining the level of liquid within a container, the transducer comprising:
a mounting head adapted for connection to the container; a housing extending from the mounting head and having a hollow interior isolated from liquid within the container; an actuator portion having:
an actuator body connected to the housing, the actuator body being restrained to travel in a linear direction with respect to the housing; andan actuator connected to the actuator body for movement therewith; a first pivot axis operably associated with one of the housing and the actuator portion; at least one sensor located in the hollow interior, the at least one sensor changing an electrical state in response to external input from the actuator; a float rod having a proximal end operably associated with the actuator portion for movement therewith along the linear direction, the float rod being constrained to pivot about the first pivot axis; and a float connected to the float rod to thereby cause pivoting movement of the float rod about the first axis and linear movement of the actuator portion in response to a change in liquid level within the container to thereby change the electrical state of the at least one sensor proportional to the level of liquid within the container. |
