Macrosensors HSD and HSDR 750 series 19 mm diameter LVDTs

The HSD and HSDR 750 series of 19 mm diameter DC-operated LVDTs, from Macrosensors, are constructed entirely of stainless steel and hermetically sealed to make them impervious to dirt, water, steam and other corrosive elements. They are suitable for use in automatic assembly equipment and other industrial applications with hostile conditions and corrosive environments.

The coil windings are sealed to IP68 and electrical termination is through a sealed axial (HSD) or radial (HSDR) connector. The radial connector 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. It also results in a shorter installed length compared to the units with axial connectors. The mating connector plug is supplied with the unit.

These linear position sensors use built-in electronics to provide a DC input and a precalibrated DC output.

The LVDTs feature high resolution and repeatability, and low hysteresis with a maximum linearity error of ±0.25%.

Operating from ±15 VDC input, the hermetically sealed position sensors offer a precalibrated 0 to ±10 VDC output for integration with PLCs, digital indicators, A/D converters, computer-based data processors and QC data collection systems.

Customisation of these LVDT position sensors is also possible, with options including teflon bore liners and metric threaded cores, as well as smaller diameters and low mass cores. Mounting accessories, core extension rods and DC power supplies are also available.
