AC LVDT displacement transducer for harsh environments
± 0.05 - 10 '', 2.5 - 3 kHz | HSA,HSAR 750 series Macro Sensors

Macro Sensors' HSA and HSAR 750 Series of 3/4 inch (19 mm) diameter AC-operated LVDTs are designed for a wide range of position measurement applications. These are rugged hermetically sealed sensors, constructed entirely of stainless steel, and intended for general industrial use. The coil windings are sealed against hostile environments to IEC standard IP-68 and electrical termination is through a sealed axial (HSA) or radial (HSAR) connector. The radial connector offers two important benefits. First, it results in a through-bore design, which permits access to either or both ends of the LVDT's core for better mechanical support and core guidance, and easier cleanout in dusty or dirty locations. The second advantage of the radial connector is shorter installed length compared to units of the same range with axial connectors. The mating connector plug is supplied with the unit.

Available in ranges of ±0.050 inch (±1.25 mm) to ±10.0 inches (±250 mm), HSA/HSAR 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.
