INFRARED RADIATOR ARRANGEMENT |
摘要 |
An infrared radiator for use in infrared analyzers includes a ceramic platelet having a front surface and a rear surface. A thin heating resistance layer is deposited on the front surface. A thin temperature measuring layer deposited on the rear surface provides a signal proportional to the platelet temperature. The signal is amplified and supplied to a sensing and control device which regulates the electrical power supplied to the resistance layer from a variable power supply whereby the platelet is maintained at a constant temperature. The platelet may be enclosed in a housing having a radiant energy transmitting window opposite the resistance layer. Electrical leads connected to the resistance layer and temperature measuring act to support the platelet in the housing.
