What is Sensor Selection?Â
Today’s sensors vary in function and structure. Selecting the appropriate sensor according to specific measurement purposes or measured objects plays an important role on the success or failure of the measurement results. The selection of an appropriate sensor is based on matching the operating characteristics of sensors to the requirements of an application. The final selection is aided by additional considerations such as cost, and impedance matching [1].
Sensor Selection Methods
Sensor Selection by Product ClassificationÂ
Selecting sensors based on characteristics such as [2] ;
Product Classification
- Photoelectric sensorsÂ
- Inductive proximity
- Pressure sensor
Sensing Method - Photoelectric
- Thru-beam
- RetroreflectiveÂ
- Diffuse reflectiveÂ
Configuration
- Mutual amplifier separated
- Power supply built-in type
Performance
- Sensing rangeÂ
Functions
- Mutual interference prevention functionÂ
Installation
Output Method
Supply Voltage
Sensor Selection by ApplicationÂ
Object-oriented method. In this case you select the best product for the objected that will be detected by the sensor. A correct understanding of the intended application is necessary for this method.
Here are some examples of the topics you should have a thorough understanding of for the intended application [3];Â
Sensing object, ex ;Â
- Size
- Material
- ShapeÂ
- Surface conditionsÂ
- Moving speedÂ
Detection purpose, ex ;Â
- Presence/ absence detection
- Color detectionÂ
- Shape detectionÂ
- Liquid levelÂ
