United States of America (Press Release) January 22, 2008 --
Constructed entirely of stainless steel, the HSE/HSER 750 Series of 19.0 mm diameter DC-operated LVDTs are hermetically sealed, making them impervious to dirt, water, steam and other corrosive elements. These CE-approved and highly rugged units are ideal for use in hydraulic cylinder positioning, valve position sensing, automatic assembly equipment and other industrial applications with hostile conditions and corrosive environments.
In addition to its heavy-duty housing, the sensor’s coil windings are sealed against hostile environments to IEC standard IP-68. The housing, bore liner and end washers are TIG welded, providing a hermetic seal free from oxidation-producing faults that may cause leakage.
A single-ended LVDT, the HSE Series 750 units terminate through a sealed axial connector that prohibits the core from passing completely through the coil assembly. Electrical termination for the HSER Series 750 DC-LVDTs, however, is made through a sealed radial connector located near one end. The radial connector offers a through-bore design that permits access to either ends of the LVDT’s core for better mechanical support and core guidance, and easier cleanout. The radial connector also offers a shorter installed length, compared to units of the same range with axial connectors.
Incorporating built-in electronics, both the HSE/HSER 750 Series 750 position sensor provide the desirable features of an AC-LVDT, such as frictionless operation and dynamic response, with the added convenience and simplicity of DC input and pre-calibrated DC output. Units offer a 0-10V DC output for easy integration with PLCs, digital indicators, A/D converters, computer-based data processors and QC data collection systems.
Available in ranges of 2.5 mm to 500 mm, the HSE/HSER 750 Series LVDT position sensor feature high resolution, excellent repeatability (repeatability error
