A counterbalance system for an upward acting door including a first casing and a second casing. Each casing includes a spring element disposed therein operable to store and release potential energy in response to movement of the upward acting door between open and closed positions. The first casing is interlockable with the second casing to accommodate and counterbalance upward acting doors of differing weights.

Counterbalance system for vertical acting doors

A transducer for determining the level of liquid within a container includes a mounting head adapted for connection to the container and a sensor assembly adapted to extend into the container. A housing of the sensor assembly has a hollow interior that is isolated from liquid within the container. A plurality of sensor elements are located within the interior. A float rod is pivotally connected to the housing and a float is connected to a distal end of the float rod. An actuator located outside the housing is operatively associated with the float rod for pivotal movement therewith. The actuator is operative to change an electrical state of at least one of the sensor elements to thereby indicate a level condition of the liquid within the container. A snap-fit assembly of the mounting head and sensor assembly is also disclosed.

Liquid level transducer with isolated sensors

A transducer for determining the level of liquid within a container includes a mounting head adapted for connection to the container and a sensor assembly adapted to extend into the container from the mounting head. The sensor assembly includes a housing having an upper portion connected to the mounting head and a lower portion that extends from the upper portion. The lower portion has a hollow interior that is isolated from liquid within the container. A plurality of sensor elements are located within the hollow interior. A float rod is pivotally connected to the housing and a float is 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. An actuator is located outside of the housing and is operatively associated with the float rod for pivotal movement therewith. The actuator is operative to change an electrical state of at least one of the sensor elements to thereby indicate a level condition of the liquid within the container.
