Abstract
A heater with an optical sensor for over-temperature protection. The heater includes a heating element and a sensor assembly including a coupler and an optical sensor. Wavelengths emanating from the heating element passes directly through the coupler to the optical sensor. The optical sensor provides an over-temperature feedback signal for limiting power to the heating element to avoid an over-temperature condition for the heating element.
