Overview

PR 812 and PRH 812 Series AC LVDTs are 0.812" (20.6 mm) diameter versions of the PR 750 Series and are designed primarily for use in legacy OEM applications and are not recommended for new designs. In most applications they are a cost effective form, fit, and function replacement LVDT for an OEM or user employing a competitor’s products of similar size and range. PR 750, PR 812, and PRH 812 Series units are available in full scale measuring ranges from ±0.050" (±1.25 mm) to ±10" (±250 mm). PR 750 and PR 812 Series units offer a core-to-bore radial clearance of 0.031" (0.75 mm), while PRH 812 Series offer a core-to-bore radial clearance of 0.062" (1.6 mm), with the standard 0.25" (6.35 mm) diameter core supplied. PR 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 these sensors is ±0.25% of full range output, using a statistically best-fit straight line derived by the least squares method.
