Abstract
A device for controlling one or more physical variables of a body or related to it, characterized in that it has, in combination; an envelope; three current passage terminals arranged in the envelope and electrically isolated from it and each other; a sensor element of the variable to be controlled; a first metallic indicator electrically isolated from the rest of the apparatus, which is driven by said sensor element to modify its angular position as a function of the instantaneous magnitude of said variable, this metallic indicator having two contact pins located one on each side of it and in electrical contact with him; a metallic spiral having one end welded to said metal indicating element and another end welded to a terminal of the three arranged in the envelope; a second hand-adjustable indicator to indicate the value of the variable that must be maintained with a certain approximation; two lateral electric contact systems subordinate to both indicators, each constituted by a metallic spiral intended respectively to make contact in a certain position with the corresponding lateral contact of the first indicator, these lateral contact systems each being constituted by a metallic spiral mounted with some previous tension, so that each spiral tends to offer some resistance when the spiral is taken in the opposite direction to that of its winding by the second indicator and therefore, to follow this indicator when it rotates in the direction of its winding, while the intermediate position of the first indicator does not prevent it, the second indicator, for the dragging of the spirals, having an electrically insulating appendix, located in the suitable position to cooperate with the extensions of contact thereof and each of these being connected two spirals to each of the other two ends electric ones located in the envelope and an electrical circuit destined to receive impulses coming from the three terminals of the envelope and to cause the necessary operations so that the magnitude of the variable to be controlled is maintained in or near the value indicated by the second indicator.
