摘要： An exterior gauge component is used to indicate a tank liquid level based on a rotational orientation of a tank magnet at a gauge head. The exterior gauge component includes a multi-track rotary encoder wheel and an optical sensor configured for reading an output of the multi-track rotary encoder wheel. The multi-track rotary encoder wheel is configured to rotate with rotation of the tank magnet such that specific ranges of rotational orientation of the tank magnet each corresponds to a specific output of the multi-track rotary encoder wheel. Each track represents a binary bit of the output read by the optical sensor. An adapter plate mounts a housing of the exterior gauge component to the gauge head and has an opening therethrough. A proximal end portion of the housing including magnets extends through the opening, and is detachable from the housing and attachable to a threaded adapter for mounting to a threaded opening of a tank.

摘要： An optical linear encoder for measuring distance includes a housing with a glass bar having precision gratings; a reading head body which moves along the housing in a measuring direction; and a carriage which is coupled to the reading head body rigidly in the measuring direction while allowing for minor movements in lateral directions. The carriage includes a scanning reticle guided along the glass bar by the carriage at a constant gap from the glass bar; a photo electronic sensor array which reads variations in intensity of the collimated light passing through both scanning reticle and glass bar, and a light source and a beam forming optics, with the beam forming being performed by an off-axis reflector.

摘要： An inspection device comprises movable equipment driven relative to a frame and provided with external and internal inspection gauges. Detection systems are provided for detecting contacts occurring between the internal and external gauges and a container. Each detection system further comprises an emitter and receiver system for emitting and receiving a light beam in a direction parallel to the travel direction of the movable equipment. A movement transformation mechanism carried by the movable equipment is also provided for transforming the travel movement of the gauge relative to the movable equipment into a movement that obstructs or ceases to obstruct the light beam.

摘要： The invention is a rotational sensor to sense an object's angle and methods to analyze the sensor output. The sensor has a first emitting source, to either emit onto, or from the object, a first receiving sensor, to receive emissions from the first emitting source, either directly or indirectly, the emissions received dependent on said angle, first receiving sensor outputting a first signal a course measurement of the angle. Also present is a second emitting source, to emit onto, or from the object and a second receiving sensor, to receive emissions from the second emitting source, either directly or indirectly the emissions received again dependent on said angle, second receiving sensor outputting a second signal, as a fine measurement of the angle. A method of use of the sensor is disclosed together with a method of combining the fine and course measurements to output a signal with zero error.
