Macro Sensors’ HSER 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 radial 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.
HSER 750 Series sensors use built-in electronics to 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 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 0.100 inch (2.5 mm) to 20.00 inches (500 mm), the HSER 750 Series sensors feature the high resolution, excellent repeatability, and low hysteresis associated with LVDT technology. Their exceptional reliability is a result of manufacturing processes and assembly techniques developed and optimized by Macro Sensors over many years of manufacturing LVDT sensors. The standard maximum linearity error for any of these sensors is ±0.25% of full scale output using a statistically best-fit straight line derived by the least squares method. A linearity error of less than or equal to ±0.10% of full scale output is available as an option.
