    Abstract: A bolometer comprising an outer surface for the thermal absorption of incident radiation in thermal contact with a radiation measurement element having a variable resistance (R) depending on the temperature, the element being in a heat feedback loop comprising a corrector for applying a heating power to a resistive heating means in order to maintain the temperature of the resistor equal to a setpoint temperature (Tref). According to the invention, the resistive heating means comprises the element, the corrector is designed to generate a frequency component (S1) of the heating power, which is applied to a coupling means provided between the element and the corrector in order to apply a DC-free signal to the element, a coupling means, separate from the means, is provided between the element and a DC bias means in order to maintain the resistor at a prescribed continuous operation point.

    Abstract: In a thermal radiation measuring arrangement, a thermal radiation detector is located at the focal point of a collecting mirror, upon which incident thermal radiation from a surface, such as a building wall, is directed. The thermal radiation detector may be, for example, a thermopile, and provides an output signal having a magnitude proportional to the amount of thermal radiation which it receives. The temperature detection means detects the temperature of the thermal radiation detector and, for example, may detect the cold junction of the thermopile. In a first operating condition, a signal summing means receives the output signal from the thermal radiation detector and the temperature detection means and provides a third output signal proportional to the sum of these first and second output signals. In a second operating condition, a signal biasing means is connected into the signal summing means. The signal biasing means provides a signal to the signal summing means to cause the third output signal to become zero when radiation is received from a reference surface. When the arrangement is in the second operating condition and directed to receive thermal radiation from a second surface different from the reference surface, the signal biasing means maintains the same level of bias to the signal summing means as it did when detecting the radiation from the reference surface.

    Abstract: A process variable transmitter for measuring a temperature in an industrial process includes an infrared detector arranged to receive infrared radiation from a component in the industrial process. A memory contains temperature characterization information which relates the infrared radiation received from the component with an internal temperature of the component. Measurement circuitry is configured to determine the internal temperature of the component based upon the received infrared radiation from the component and the temperature characterization information.
