(2) Temperature Sensor for Isothermal Oven
A single oven unit has two temperature sensors:
For control: controlling the temperature of the isothermal oven
For protection: detecting abnormally high temperature
The temperature sensor for the isothermal oven is a platinum resistance temperature detector
(Pt100 ohm).
