Abstract

L'invenzione concerne un dispositivo potenziometrico, in particolare per rilevare la posizione di un pistone in un attuatore azionabile da fluido sotto pressione, costituito da una disposizione di resistenza e da una disposizione a contatto strisciante, guidata scorrevolmente su quest'ultima, quali elementi funzionali, rispettivamente uno di entrambi gli elementi funzionali trovandosi in collegamento efficace con rispettivamente uno degli elementi di apparecchio spostabili fra loro relativamente.Secondo l'invenzione viene proposto che è prevista una base di supporto (2, 30, 61), la quale dispone di una parte superiore (28) e di una parte inferiore (26) e la disposizione di resistenza e/o quella a cursore sono fissate sul lato frontale (29) della parte inferiore (26), che il pistone (10, 34) o lo stelo di pistone (8) è dotato di una molla di richiamo (9) e la molla di richiamo è dotata di un elemento di azionamento (3), il quale, riferito alla corsa di pistone, effettua movimenti riduce The invention relates to a potentiometric device, in particular for detecting the position of a piston in an actuator that can be operated by fluid under pressure, consisting of a resistance arrangement and a sliding contact arrangement, slidingly guided on the latter, as functional elements , respectively one of both functional elements being in effective connection with respectively one of the apparatus elements which can be moved relative to each other. According to the invention it is proposed that a support base (2, 30, 61) is provided, which has a upper part (28) and a lower part (26) and the resistance and / or slider arrangement are fixed on the front side (29) of the lower part (26), that the piston (10, 34) or the rod piston (8) is equipped with a return spring (9) and the return spring is equipped with an actuation element (3), which, referred to the piston stroke, performs movements and reduces nti la corsa, che la parte inferiore (26) della parte di supporto (2, 30, 61) è conformata in modo che essa è inseribile in una apertura (5) dell'attuatore in direzione verso l'elemento di azionamento in modo che il lato frontale (29) sia contrapposto all'elemento di azionamento (3). nti the stroke, that the lower part (26) of the support part (2, 30, 61) is shaped so that it can be inserted into an opening (5) of the actuator in the direction towards the actuating element so that the front side (29) is opposite the actuating element (3).
