Liquid Level Transducer with Isolated Sensor

A transducer for determining the level of liquid within a container, the transducer comprising:

• a mounting head section adapted for connection to the container;
• a housing section extending from the mounting head section and having vertically oriented side walls adapted for extending into the container, and a hollow interior formed between the side walls, the hollow interior being isolated from liquid within the container;
• a sensor assembly adapted for location in the container, the sensor assembly comprising:
• a vertically oriented sensor board located within the hollow interior of the housing section between the side walls;
• at least one sensor element located on the vertically oriented sensor board within the hollow interior of the housing section;
• a float rod pivotally connected to the housing section;
• a float connected to a distal end of the float rod to thereby cause pivoting movement of the float rod in response to a change in liquid level within the container;
• and
• an actuator located outside of the housing section and operatively associated with the float rod for pivotal movement therewith, the actuator being operative to change an electrical state of the at least one sensor element to thereby indicate a level condition of the liquid within the container.
