Macro Sensors LVDTs: HSAR 750-006 Hermetically Sealed LVDTs- METRIC

Description

Macro Sensors’ HSAR 750 Series of 19.0 mm diameter AC-operated LVDTs is 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 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 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.

Available in ranges of ±1 mm to ±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 smaller diameter, low mass cores. In addition, Macro Sensors can provide 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 operating temperatures.

All HSAR 750 Series LVDTs will operate properly with any conventional differential input LVDT signal conditioner. Ranges of 25 mm or greater will also work with ratiometric LVDT signal conditioning. Macro Sensors offers a full line of LVDT signal conditioners that will deliver optimum performance from any HSAR 750 Series LVDT.
