1. The sensor has a 2.5 ms refresh rate, it is ultra sonic looking down at a part that travels undernieth the sensor in 20-30 ms.
2. The controller is a Yaskawa MP2300, it is both a PLC and motion controller. A IO block provides analog inputs to the system. The IO scan time is too slow to repeatably detect the peak voltage signal. The scan time is slowed because of control of 13 axes.
3. When I run the same part under the sensor 20 times, I get 20 different peak readings in the PLC. This translates into real world measurements which fluctuate 10 mm, for a part that is approximately 90 mm tall. We've proved the sensor is repeatable and there is no noise by measuring the voltage on a seperate oscilloscope which showed excellent results.
I was looking for an off the shelf solution, maybe DIN rail mountable. This should allow me to feed the sensor's voltage signal as an input and accept control signals such as: Acquire and Reset.
Thanks for any help you can provide.
