About the HSD-Series Hermetically sealed DC-operated LVDT position sensor
The HSD and HSDR 750 Series of 3/4 inch (19 mm) diameter DC 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 (HSD) or radial (HSDR) 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.
HSD and HSDR 750 Series sensors use built-in electronics to provide the desirable features of an LVDT, such as frictionless operation and dynamic response, with the added convenience and simplicity of DC input and precalibrated DC output. They are designed to operate in conjunction with PLCs, digital indicators, A/D converters, computer-based data processors and QC data collection systems.
Available in ranges of ±0.015 inch (±0.38 mm) to ±10.0 inches (±250 mm), HSD/HSDR 750 Series sensors feature the high resolution, excellent repeatability, and low hysteresis associated with LVDT technology.
