Heatable infrared sensor and infrared thermometer comprising such an infrared sensor |
摘要 |
An infrared sensor with an electrically heatable sensor housing. The housing including a heating device in the form of a strip conductor-like electric heating track, which is controlled by a control device, and applied onto a ceramic substrate. The ceramic substrate comprises an electrically insulated ceramic material providing adequate thermal conductivity and preferably forming the bottom of the sensor housing, and carrying at least one infrared sensor element, e.g., a thermopile sensor. The ceramic substrate having electric strip conductors serving as a contact surface for a corresponding (not-shown) housing cover and through-hole contacts serving as electrical connections between the top side and the bottom side of the ceramic substrate. The electric heating tracks and strip conductors in a preferred embodiment comprise thick-film tracks. The infrared sensor being suitable for a measuring tip of an intra-auricular infrared thermometer. |
