Ni-1000 Bridge driver

00:37:23

Circuit for driving Nickle-1000 temperature sensors and translating them to 0-10 V. The 350Ohm resistor on the bottom left represents the Ni-1000 and can be adjusted to 1850Ohm to test the 0-10V Signal. The Ni-1000 has a (more or less linear) spectrum from those 350-1850Ohm at -60 to 150°C.

Maybe the ~0.6mA would actually heat the sensor too much sou you could adjust the 20K resistors up and adjust the amplification divider at the opamp to reach the 10v again. The higher the amplification the more critical this gets.

There are most certainly better ways of doing this but i wanted to do it on my own.
