  1. [SOLVED]Closed: Re: How to use NTC temperature sensor in production

    Why do you think I will not answer that..can you please clarify..why one should not take advantage of this forum ?? I have been using this forum for the last 8 years and everyone helps as per his/her...
  2. [SOLVED]Closed: Re: How to use NTC temperature sensor in production

    yes it meets my requirement but we have to invest effort in making sensor housing (enclosure)..
  3. [SOLVED]Closed: Re: How to use NTC temperature sensor in production

    Can you please suggest any band gap device for the same purpose..I just want avoid calibrating all the sensor in production.

  7. [SOLVED]Closed: Re: Using LED driver IC to Drive Proportional Solenoid Valve

    Yes I understand your point ..But this is proportional control valve and it is normally closed. If I can get the normally open valve then I have to close it till the flow reaches its set point.
  8. [SOLVED]Closed: Re: Using LED driver IC to Drive Proportional Solenoid Valve

    If you see the data sheet of the solenoid the coil assembly is on the top of the flow opening and also the flow rate is below 15 LPM . so it is not dissipating the heat properly unless I provide a...
  9. [SOLVED]Closed: Re: Using LED driver IC to Drive Proportional Solenoid Valve

    Yes jiripolivka data sheet of the solenoid says ..opening of the valve is proportional to current flowing through it. I will test the circuit tomorrow and let you know how it goes.. thank you for...
  10. [SOLVED]Closed: Using LED driver IC to Drive Proportional Solenoid Valve

    Hello everyone,

    I am using PWM to control a proportional solenoid valve(12 V,340mA) to control air flow rate. The control system is working but the coil of the solenoid is getting very hot. I want...
