Macro Sensors' PR 750 Series of 3\/4 inch (19 mm) diameter AC-Operated LVDTs are general purpose contactless linear position sensors for both OEM applications and end user requirements. They are available in full scale measuring ranges from ±0.050 inch (±1.25 mm) to ±10 inches (±250 mm) and offer a core-to-bore radial clearance of 0.031 inches (0.25 mm) with the standard core supplied. PR 750 Series sensors feature the high resolution, excellent repeatability, and low hysteresis associated with LVDT technology, as well as the highest sensitivity consistent with good linearity. The maximum linearity error for any of these sensors is ±0.25% of full range output, using a statistically best-fit straight line derived by the least squares method.
