Hi guys! I need to measure a sheet thickness. The sheet is going through between rolls. As the sheets thickness changing the rolls getting rise or descend. I have an ultrasonic sensor. My problem is when the thickness is changing like From 1 mm to 2 mm the ultrasonic sensor signal is not changeing in a straight proportion. The sensor working well around at 2.5 mm. I tought about how to calibrate it correctly. If I put first 0.2 mm sheet then i not it down the value of the sensor then put 0.4 mm sheet And so on....and making little sections like how much is the sensor value and decide by my calculation. Do you know anyone a better solution for this ? Also you guys do you think it will work ? I should write the program in rs logix 5000. Thanks in advance any idea or tips.
I have project where I need to measure motor current but I do not need to control the speed of the motor since it would always be running at full speed. Do I still need to use VFD to get feedback or is there cheaper way to measure the current?
Hello, I have a cj2 plc, and i would like to use two pt100 to measure, and just show the results on an hmi screen. I started to look at the Cat. No. W396-E1-03 SYSMAC CJ Series CJ1W-TC@@@ Temperature Control Units manual, but i don`t understand fully, that is these card are only for temperature controls? What is the easiest way to have the readings? it doesn't need to be the cheapest solution. And especially how is the programming works? Is there a special unit are i read about but how is the adressing works? Im completely new to omron (i know siemens) so any linked guides are welcome!
Hi everyone! I have this simple problem, but cant get over it. I have structured ladder/FBD Project and i use GX works2. As topic tells I use analog signal from field. Now, i need to compare this value X (from field) to Values X1 and X2, meaning if value X is between values X1 and X2 then M1 is true. Ok, but what function i need to use for this? Best regards, Juha.
