Motion Control Proximity Dimension-Level
 

Dimension & Level applications include measuring the level of liquids and solids in a tank, bin or container, or the height of an object or stack of objects involved in a process or machine. In these applications the sensor is mounted from above and looks down on the measured object or material. As the height or level increases the resulting distance measurement between the sensor and object becomes shorter. Sensor outputs can be user-configured to change in direct or inverse proportion to the level or height.

NOTE: Senix® Ultrasonic Sensors should not be used in any application where personal safety or hazardous materials are involved!

Stack Height

In some indexing and stacking operations the height of a stack of flat objects is required for full/empty detection, or to control the level of the stack for proper machine operation. These situations are easily handled using a Senix® Ultrasonic Sensor, with relay and/or proportional outputs available for control.

Object Dimensions

Object dimensions can be obtained. Height can be measured as the difference between the object and floor distances. Width of an object can be determined by measuring the object from 2 sides. If one side of the object is always in the same position (floor, against a wall or guide, etc), then only one sensor is required for that dimension.

Height & Size

Senix® Ultrasonic Sensors can be used to discriminate objects by height or size. This could involve selecting boxes on a conveyor belt, rejecting out-of-dimension objects, or similar applications.

Liquid Level

 

 A common application is the measurement of the liquid level in a closed or open top tank. These applications range from benign open top tanks in clean environments to severe process environments involving high temperature and pressures, caustic or hazardous materials. Senix® Ultrasonic Sensors are useful in benign and mildly challenging environments and a variety of support accessories are available including displays, transducers and splash guards. Senix® Ultrasonic Sensors should not be used in severe environments involving pressure, high temperatures, or hazardous or incompatible materials. Contact the factory if you have any questions about your particular requirement.

Solids Level

Dry material level in bins or hoppers can be measured if the materials provide sufficient ultrasonic echo for reliable detection. Some materials absorb sound, while others are easily detected. The incline of the material must also be such that a proper sound echo is obtained at those times when the level measurement is required. Contact the factory if you have any questions about your particular requirement.
