Abstract
The utility model relates to a radiation-proof high-altitude meteorological detection temperature sensor, which comprises a circuit board with a sensor element and a fixed element, wherein, the sensor element is a thermistor, both ends of which are welded on the printed circuit of the circuit board. An insulating barrier is coated on the circuit board and the thermistor, and a metal membrane is coated outside the insulating barrier and is a metallic aluminium membrane or an alloy aluminium membrane which can reflect the solar radiation and the long wave calorific radiation. The utility model is arranged on a sonde and is used for measuring the high-altitude atmosphere temperature. The insulating barrier and the metal membrane effectively protect the circuit and the thermistor on the circuit board, and avoid the affection of the solar radiation and the long wave calorific radiation to the thermistor, the measurement precision is guaranteed, the service life of the sensor is lengthened, and the favorable detecting work is guaranteed.
Description
Technical field
The utility model relates to a kind of sensor, particularly a kind of aerological sounding temperature sensor.
Background technology
Existing aerological sounding temperature sensor comprises the wiring board of sensing element and retaining element, after sensing element that exposes in detection process and wiring board are subjected to solar radiation and the thermal-radiating influence of long wave, measuring error strengthens, and the life-span of sensor also can shorten.
The utility model content
The purpose of this utility model provides a kind of radiation proof aerological sounding temperature sensor, solves to be subjected to solar radiation and long wave is thermal-radiating influences the technical matters that measuring error strengthens in detection process; Solve the problem that prolongs sensor life-time.
The technical solution of the utility model: radiation proof aerological sounding temperature sensor comprises the wiring board of sensing element and retaining element, it is characterized in that: its sensing element is a thermistor, its two ends are welded on the wiring board P.e.c., scribble insulation course on wiring board and the thermistor, insulation course is coated with reflected solar radiation and the thermal-radiating metal film of long wave outward.
Above-mentioned metal film is aluminium film or alloy aluminum film.
Above-mentioned thermistor is mixed oxide thermistor or semiconductor temperature sensor.
Beneficial effect: the utility model adopts the thermosensitive resistance measurement atmospheric temperature.Scribble insulation course and metal film on thermistor and the wiring board, metal film can reflected solar radiation and long wave heat radiation.The aerological sounding temperature sensor is installed on the sonde, is used to measure the upper atmosphere temperature.Sonde is to carry lift-off by balloon, can survey temperature, humidity, air pressure, wind direction, the wind speed in high-altitude.Insulation course and metal film have effectively been protected circuit and the components and parts on the wiring board, have prevented to be subjected to that solar radiation and long wave are thermal-radiating influences, and reduce measuring error, have prolonged the life-span of sensor greatly, guarantee that detection operations carries out smoothly.
