Abstract: According to an aspect, a UV radiometer is provided. The UV radiometer includes a sensor assembly and a sensor controller. The sensor assembly includes a UV sensor element and a temperature sensing component configured to perform a thermal adjustment of a sensed UV input from the UV sensor element to produce a compensated UV signal. The sensor controller includes a signal conditioning circuit configured to receive the compensated UV signal from the sensor assembly and produce a conditioned and compensated UV signal. The sensor controller also includes a communication interface configured to transmit the conditioned and compensated UV signal to a UV process controller.
