Hi

Thank you for your post.

Unfortunately I do not have an equation that I can supply you with. You may have to try and find this from the manufacturers of the sensor.

Best Regards

Hello,

There are various equations that can do this for you. There are also various lookup tables that can also perform this function.

A simple google search will find these for you:

hi
i want help in my project
i want any circuit related to change temperatue into voltage or temperature sensing ic with o/p voltage ranging from 0 -10 volt
temperature ranging from 0-100centigrade

o/p changing linearly with 100mV/C

if anyone can help than do reply.

Use an LM-35 (0-100 mV represents 0-100 C) and an appropriate amplifier with the required gain (100) to get 0-10 Volts.
