TM Division Of Howard A. Schaevitz Technologies, Inc. Innovators in Position Sensing Description Macro Sensors’ HSAR 750 Series of 3/4 inch (19 mm) diameter AC-operated LVDTs is designed for a wide range of position measurement appli- cations. These are rugged hermetically sealed sensors, constructed entirely of stainless steel, and intended for general industrial use. The coil wind- ings are sealed against hostile environments to IEC standard IP-68 and electrical termination is through a sealed radial connector located near one end. The mating connector plug is supplied with the unit. 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 guid- ance, and easier cleanout in dusty or dirty loca- tions. The second advantage of the radial con- nector is shorter installed length compared to units of the same range with axial connectors. Available in ranges of ±0.050 inch (±1.25 mm) to ±10.0 inches (±250 mm), 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. Macro Sensors offers several standard options that permit a user to customize HSAR 750 LVDTs, including Teflon® bore liners and metric thread- ed cores, as well as smaller diameter and low mass cores. In addition, Macro Sensors can pro- vide a range of mounting accessories and core extension rods. On special order, the HSAR 750 Series can be constructed for resistance to mild nuclear radiation, as well as for immersion in pressurized fluids and to withstand higher oper- ating temperatures. All HSAR 750 Series LVDTs will operate properly with any conventional differential input LVDT signal conditioner. Ranges of 1.00 inches or greater will also work with ratiometric LVDT sig- nal conditioning. Macro Sensors offers a full line of LVDT signal conditioners that will deliver optimum performance from any HSAR 750 Series LVDT. Details can be found in series 9000 technical bulletins.
