DO NOT ground the inputs or connect them to pin 5. An LVDT transducer or LVDT is a miniature transformer having an armature core and a shaft that is free to move in a linear axis. Difference Between LVDT & RVDT One of the significant difference between the LVDT (Linear variable differential transformer) and the RVDT (Rotatory Variable Differential Transformer) is that the LVDT changes the linear motion into the alternating electrical signals whereas the RVDT translate the angular displacement into an electrical signal. 0000001486 00000 n To summarize, “The LVDT closely models an ideal zeroth-order displacement sensor structure at low frequency, where the output is a direct and linear function of the input. The minimum length of the sensor is its body, and the core can extend only as far as the length of the body. 189 0 obj <>stream ���$.E-j�5l0�hGoт*��1}#��|?�_�ή(���+�ś +�MLJ���b�5ܴUd�N��C_�irj-}��%fT��A��u�_� Q4�;�S�x�T=�y� ���� 0000002732 00000 n 0000007965 00000 n ���� Adobe d� �� � AC LVDT DISPLACEMENT SENSORS U ±2.5 to ±150 mm travel U <0.2% Linearity U Rugged 19 mm Dia. - 3 - TECHNICAL DRAWING SENSOR LVPH A 1 9 Ø 5 17 25 SW 30 20 5 M Ø 5 7 10 10.5 M24x1.5 Ø 40 B Measurement range 25 50 100 150 200 500 Housing length A 122.5 188 273 295 373 701 Centre measuring position B 59 82 98 105 125 268 Rod length 120 175 245 310 324 670 TECHNICAL DRAWING ELECTRONICS LVA 0000041827 00000 n essentially a non-contacting transducer that can convert the rectilinear motion of an object to which it is mechanically coupled to an analog signal which can be used to determine the displacement of the object 0000008956 00000 n 0000007139 00000 n �3��2�� ͽ�?x�7��]�g7;o�HXC���4�$��659H�A��YH���^���ؗ������g��ƛ�e1���_E�=M��ʋW�)�s?ş�_�b��,��[����w�����~���N�\K����.vc?G$�8�)��?���~�j�d�"Ĥb��Q4� ���^�\����Wg��){ ��U�.�=�9XF����Џ��%yYx�)H��7��j. 0000009619 00000 n This is necessary to control the resulting horizontal movement of the slabs.
