Please help me in solving this problem :


Design a circuit to control the temperature of a water bath at a setpoint temperature of 75 degree celcius. Choose a resistive sensor and draw up a bridge circuit which will provide a control around the setpoint. Suggest values for all components to be used. Heat can be supplied to a heater in the bath using power amplifier which requires 0 to +0.5 V for zero to maximum power output.

 

The Homework Help section asks that you post up the work you have done so we can see it and find where you went wrong, or suggest better approaches. We will not do all your work for you, no matter how little time is left before it must be submitted.

If you are in doubt about how to structure your post and what to include please read this thread.

Thank you.

 

Hello,

So you will need to make a control loop.
Take a look at this page of the EDUCIPEDIA on control systems.
http://www.educypedia.be/electronics/controlpid.htm
With the information over there you will be able to design it probably.
