I have an ultrasonic sensor that I can test it with, I'm not sure what freq and sound level range it works with but I can try it. The machine uses some air because it has multiple solenoids, I'm sure the air pressure fluctuates enough that a discrete pressure switch would'nt see the leak...
Does anyone know of a sensor that detects sound and has an analog output. It will be in a noisy environment but would need to be able to detect the sound of an air leak. To the human ear it's easily heard but there's not always someone there to hear it. The analog output would be input to the...

This is an analog scaling math function I have used many times with different processors. I'm not familar with the DL205, but the logic should be the same. Let's take your digital mic, let's say it has a +/- 10 volt output that is equal to 0 to 25 mm. If the analog input card on the plc is...
I'm starting a new multi chemical pump project. We have a dozen or so pumps on PID loops and will be ratio the streams. We plan to use an AB control logix processor and wonderware intouch as an interface. Most of my expericence has been with SLC 500's ML1500's. The control logix PID loop looks...
I'v always been told that you can't write directly to an output on slicks. Have you tried to mov the value of this output to an integer or binary, and tried to read or write to that address.
