Gap displacement sensor overview

     

          Miran Technology gap sensor can measure the gap or distance between two objects. Its principle is to use the differential transformer displacement sensor (LVDT) principle to determine the gap or distance between two objects by measuring the position change of the iron core in the coil.

         Gap sensor features: large measurement range, high resolution, good repeatability, built-in coil without sliding contacts, long service life, external transmitter can output signals of 4-20mA, 0-5V, 0-10V, ± 5V, ± 10V, RS485.
