The M-12 series LVDT is wound on a ribless bobbin providing the smooth transfer function required for the most demanding materials testing and position feedback applications. The new M-12 series coil design has been optimized to provide the best possible Temperature coefficient of Precision distribution, tapered layer windings provide excellent stroke to length ratio, with no sacrifice in sensor linearity. Available ranges are from ± 5 mm to ± 150 mm. Excellent Stroke To Length Ratio Smooth Transfer Function Constant Sum Of Secondaries Typical T/C 150 PPM/Degree C. At 2.5 to 5.0 kHz Shielded Stainless Steel Case +/-10 to +/- 100 mm Strokes Materials Testing Extensometers
