Hi Gurkan and Mike,
The LM35 has a typical accuracy ±0.25°C at room temperature and ±0.75°C from -55°C to 150°C. Most of our temperature sensor products are sensed the temperature through the sensor’s package and its metal lead. The LM35 metal can package might be suitable for your project since it will have a dominant thermal path through the package. You might need to seal the package on your aluminum plate or pan with the epoxy high temperature. You also need to seal the pins too.
I hope this helps. Please let me know if you have further question.
