Hello!
I would like to ask someone for help regarding PT1000 temperature sensor simulation. I am interested in the following cases:

1. Dependence of voltage on temperature in the range from 1 to 80 degrees Celsius (per degree);

2.Simulation when the sensor is shorted;

3.Simulation with missing sensor;

I am currently using proteus as a simulation product, but I don't know how I can get this information out of the DC Sweep Analysis. Any help would be in use.

Thanks and sorry in advance!
Best Regards!

 

hi J,
This is your basic circuit in LTS, the sim shows the fixed Temperature of 0 degC.
I will check the points you have posted.

hi J,
This is what LTS shows for to 0C thru 100C.
PT1000 from 1000R thru 1385R, linear sweep.

hi J,
PT1000 shorted and open circuit.

Added: typical PT1000 resistance versus temperature data

 

hi J
I would suggest this small change to make your amp differential, from Vo=0v at 0C thru 1.6V at 80C, ie: 20mV/degree C
