{"id":345,"count":24,"description":"Linear transducer: the ideal solution for measuring linear displacements in industry <\/strong>\n <\/strong>\n\nA linear transducer<\/strong> is a device whose function<\/strong> is to detect<\/strong> the position<\/strong> and velocity<\/strong> of mechanical movements<\/strong> in a straight line.\n\nAlso discover pressure transducers<\/a>. <\/strong>\n\n <\/strong>\nLinear transducer: what is meant by it <\/strong>\nAs previously mentioned, a linear transducer is a device whose function is to measure linear displacements<\/strong>. Its operating principle is similar to that of incremental rotary encoders. However, while encoders read a circular reference scale, linear transducers operate on a straight graduated scale<\/strong>. \n\nThere are several types of linear transducers<\/strong>, which differ<\/strong> according to the displacement detection technique<\/strong> used. Among the main ones we find: \n\n \tincremental linear transducer<\/strong>: the operating principle<\/strong> of these transducers is similar<\/strong> to that of the incremental rotary encoder<\/strong>. In the incremental linear transducer, the disk is replaced by a graduated scale, in which bright zones alternate with opaque zones; \n\n\n \tpotentiometric linear transducer:<\/strong> is a device that converts the position<\/strong> of an object into a change in electrical resistance<\/strong>. These linear transducers consist of a resistive element, usually a wire or a metal layer, wound on an insulating support. A mobile contact is able to move along the conductor, depending on the position of the object to be measured; \n\n\n \tmagnetostrictive linear transducer: <\/strong>uses the principle of magnetostriction<\/strong>,<\/a> according to which certain materials expand or contract when placed in an alternating magnetic field.\n\nLinear transducer: operation<\/strong>\nThe linear transducers described above<\/strong> are all incremental types<\/strong>: they measure a series of displacements rather than an absolute position.\n\nTheir operation varies<\/strong> depending on the type used. Let's see how they work: \n\n \tmagnetic linear transducer<\/strong>: operates based on the magnetic principle. The cursor contains a magnet that reacts with a polarized magnetic strip. The advantage<\/strong> of this system is that it has no electrical contact on the cursor<\/strong>, which limits wear<\/strong> from friction and allows for greater precision and speed<\/strong>. Furthermore, magnetic systems are less sensitive to dirt than optical systems; therefore, they are more suitable for applications in industrial environments where processing involves the presence of dust or oils; \n\n\n \toptical scale linear transducer<\/strong>: utilizes optical sensors or photodiodes that read high-precision graduated marks on a straight guide. The length of the movement made is measured based on this information. Optical scales <\/strong>are typically used<\/strong> on machine tools<\/strong>; \n\n\n \tPD-PE series incremental linear transducer<\/strong>: operates based on the optical principle of reading a graduated scale, similar to optical scales. However, the reading head and the measuring scale are contained in a robust aluminum housing that ensures protection against environmental agents. This feature makes the mounting of the transducer particularly practical<\/strong>, as it is fixed to the machinery via mounting brackets or ball joints at the ends. The reading precision<\/strong>, ease of mounting<\/strong>, and wide choice of measuring strokes (from 60 to 990 mm) make this type of linear transducer suitable for all applications<\/strong> where it is necessary to measure a linear displacement. \n\nLinear transducer applications: which sectors to use it in<\/strong>\nIn the industrial field, linear transducers are used<\/strong> on all types of automatic operating machines. They are usually paired<\/strong> with counting<\/strong>, display<\/strong>, and control systems<\/strong>. \n\nThe linear transducer is used in a wide range of sectors<\/strong>, including:\n\n \thydraulic;\n \tautomation;\n \trobotics;\n \taeronautics.\n\nThe choice of the most suitable type<\/strong> of linear transducer depends<\/strong> on a number of factors, including:\n\n \trequired precision<\/strong>;\n \tresponse speed<\/strong>;\n \tenvironment<\/strong> in which the transducer will be used\n","link":"https:\/\/sensorline.biz\/en\/linear-transducer\/","name":"Linear Transducer","slug":"linear-transducer","taxonomy":"category","parent":0,"meta":[],"acf":[],"_links":{"self":[{"href":"https:\/\/sensorline.biz\/en\/wp-json\/wp\/v2\/categories\/345","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/sensorline.biz\/en\/wp-json\/wp\/v2\/categories"}],"about":[{"href":"https:\/\/sensorline.biz\/en\/wp-json\/wp\/v2\/taxonomies\/category"}],"wp:post_type":[{"href":"https:\/\/sensorline.biz\/en\/wp-json\/wp\/v2\/posts?categories=345"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
