Non-traditional housings styles are exemplified on the Bi20R-Q14-LU ring style and the Wi70-M18-LIU5 probe style sensors. These analog sensors are specified with a repeatability of less than 0.5 percent and linearity of 3 percent. The Bi20R-Q14-LU is a three-wire, 15 to 30V dc sensor with a 0 to 10V output in a ring style housing with a 20-mm diameter hole. This sensor is fit for the identification and sorting of small parts (such as screws) as the sensor generates a different output signal for each size part. Position control applications can be resolved with the Bi20R-Q14-LU by means of a cone-shaped target as well as the detection or measurement of tools (such as drill bits). The Wi70-M18-LIU5 is a four-wire, 15 to 30V dc analog sensor with either a 0 to 10V or 4 to 20 mA output. Housed in a standard 18-mm barrel, the 75-mm probe has a linear operating distance of 70 mm. This probe style sensor can detect all metals and can be used in a variety of areas, such as the positioning of metal parts as they move over the length of the probe. TURCK http://rbi.ims.ca/4912-550
For industrial control applications, or even a simple assembly line, that machine can go almost 24/7 without a break. But what happens when the task is a little more complex? That’s where the “smart” machine would come in. The smart machine is one that has some simple (or complex in some cases) processing capability to be able to adapt to changing conditions. Such machines are suited for a host of applications, including automotive, aerospace, defense, medical, computers and electronics, telecommunications, consumer goods, and so on. This discussion will examine what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
