  1. Helium pressure sensor

    Yes, this is for a safety feature. I'll try looking into pressure switches in the market. SKR.
  2. I have helium cylinder. I want to have a control application where the process should stop when the pressure in the cylinder decreases to certain level. Can any one help me to find the right sensor? or application to do this. Thank you, SKR.
  3. Buy what PLC?

    I recently started using Micro 800 series Allen Bradley PLC's for small control applications. They are easy to work with also they are cheaper....around 100-150$. Some of them have limited I/O's. Good Luck!
  4. I'm planing to use a limit switch, I don't know if that can be helpful. I think inductive sensor has limited range in millimeters. Thanks for the suggestion..
  5. Thanks for the reply, I'm looking for a low cost system. This looks a bit expensive, but I'll go through it. Regards, SKR.
  6. Sorry, the file was missing. I've attached it now. There is no existing control system. The tubes are placed in tub as shown. Its not important to check the temperature or number of tubes, I just need the fan to be on for 10 minutes. Thanks, SKR
  7. I've a control application. I've attached an image of it for reference. The application is as follows... When tubes are not present on the conveyor the fan is not on. When tubes are present the fan runs for 10 min. When the 10 min is up, fan shuts down, and alarm is enabled. When the tubes are removed at the end of cooling cycle the alarm disabled. The cycle then resets. The Fan is on 120V AC, I want to do it with minimum cost. What type of sensors are more suitable for such application.? Regards, SKR
  8. Micro 810 application.

    I'll talk to my distributor, right now I'm looking into some you-tube videos. Its always self learning when it comes to PLC's :)
  9. Micro 810 application.

    How different is Ladder programming for 810 controller when compared to RSlogix 500?
  10. Micro 810 application.

    May be I should use an Alarm/light instead of e-stop. Thanks for the reply. I'll update a ladder logic here soon. Thanks, _SKR.
  11. Micro 810 application.

    Hello all, I'm quiet new to control and logic systems, I'm still learning. I have to develop a circuit/logic for an application. I was wondering if Micro 810 can be used for this & the objectives of the application are: 1. whenever Signal A(0-24V) is high for the first time in the cycle and Signal B(0-24V) goes high then the solenoid X(24V) should be ON. 2.when signal B is low then the solenoid X should be OFF. 3. If in an instance signals A and B are opposite to each other for more than 2 seconds then a signal should be sent to E-stop. If not Micro 810, what are the other products that are suitable for such application? I know this can be done by normal relay board and some timers; I want to use a controller for this if its cheaper in price. Regards, _SKR
  12. Did you change your Laptop's IP address ?? It should match 192.168.124.XXX (XXX-- can be any number except 200) Are you using good Ethernet cable? On Kinetix 300 You should be able to see communication activity light ON.
  13. Hello every one, I'm quiet new to PLC programming and controllers. I've started a project on designing a CNC tube bending using ML 1400 and Kinetix 300. Until now all I could do is run a 3 axis sample program that makes all the three motors rotate with the help of HMI panel. I got this program from AB website. I was wondering if any of you have experience in programming bender machines? I'm looking for some support and guidance; else let me know if I need to look somewhere else. Any knowledge in tube bending with 3-axis rotation will help. Thanks in Advance, SKR.
  14. Liquid level control

    Not a problem. If you come across any other sensors please post the link here. I'm looking for a simple and easy to use sensor. Best Regards, _SKR.
  15. Liquid level control

    Thanks a lot for all your suggestions. I meant opaque--> not transparent its a solid steel material. The cylinder tanks are 5-10 liters in volume.
