| description | The invention relates to a temperature sensor (1) that comprises of a first circuit (2) adapted to generate temperature coefficient signal that corresponds linearly with respect to the temperature being sensed, and a second circuit (3) adapted to vary the generated signal for allowing operation in varied on-field temperatures condition. The second circuit (3) is a temperature coefficient controller having means for allowing adjustable circuit parameter. It is connected to the output terminal of the first circuit (2) and the temperature coefficient controller of the second circuit (3) includes an amplifier (4), a variable resistor (5) and a resistor (6) whereby the resistor (6) is connected to the input terminal of the second circuit and the variable resistor acting as feedback resistor to the amplifier. Application with respect to soil study such as pH measurement, soil-based nutrients analysis and other are some of the possible applications of the temperature sensor.
L'invention porte sur un capteur de température (1) qui comprend un premier circuit (2) apte à générer un signal de coefficient de température qui correspond de façon linéaire à la température détectée; et un second circuit (3) apte à faire varier le signal généré pour permettre un fonctionnement dans des conditions de températures variées sur le terrain. Le second circuit (3) constitue un contrôleur de coefficient de température muni de moyens pour permettre la mise en oeuvre d'un paramètre de circuit ajustable et est connecté à la borne de sortie du premier circuit (2). Le contrôleur de coefficient de température du second circuit (3) comprend un amplificateur (4), une résistance variable (5) et une résistance (6) connectée à la borne d'entrée du second circuit; la résistance variable sert de résistance de rétroaction à l'amplificateur. Entre autres applications possibles, on peut citer l'analyse des sols, telle qu'une mesure de pH et l'analyse des éléments nutritifs du sol. |
