Improvements in devices for determining the intensity of radiation sources

... 936,757. Temperature determination. PHILIPS ELECTRICAL INDUSTRIES Ltd. May 8, 1961 [May 11, 1960], No. 16629/61. Class 40 (3). A device for measuring the intensity of a radiation source moving across its field of view, and more particularly a hot axlebox detector, comprises two radiation sources 2, 3, connected in opposition and associated with a single optical system in such a way that two successive output pulses are obtained when a source passes the device. The optical system may be a concave reflector 4 and radiation from a hot axle box 1 moving in a direction 6 results in a first output pulse from one detector followed by a second pulse of opposite polarity from the other. The peak-to-peak amplitude is a measure of axlebox temperature and a device 5 indicates when the temperature exceeds a permissible value. A numerical count of signals may also be made. Variations in background radiation affect both detectors similarly and are substantially cancelled out.

Temperature sensor for a high speed rotating machine

Infra-red sensors are often used in turbo molecular pumps to detect the temperature of the rotor or other mechanical parts and therefore indicate imminent, or potential, running failures. As deposits build up on either the infra-red sensor, or on the surface being monitored, the reading given by the sensor may not be a true representation of the actual surface temperature which can cause the pump controller to fail to stop the pump in time. The present invention provides a method and device for calibrating the sensor by creating a determined temperature rise in the sensor whilst keeping the rotor at ambient temperature. In particular the present invention uses the motor stator as the heater for causing the temperature increase.
