Separate Free Core AC / DC LVDT Position Sensors

Macro Sensors’ DC 750 Series of 3/4 inch (19 mm) DC-operated LVDTs are designed for a wide range of position measurement applications. They 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.

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.

Macro Sensors’ HSTA 750 Series of 3/4 inch (19 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 use at high temperatures (400°F). The coil windings are sealed against hostile environments to IEC standard IP-68 and electrical termination is through a sealed axial connector. The mating connector plug is supplied with the unit.

Macro Sensors’, a TE Connectivity company, HLR 750 Series LVDT position sensors are specially designed for use in gas turbine & other hazardous location environments. These hermetically sealed AC LVDTs are UL listed for use in Class 1 Division 2 Non-Incendive environments Gas Groups A, B, C, and D. Available in measuring ranges from ±1 inch to ±10 inches, HLR 750 Series LVDT position sensors feature high resolution, excellent repeatability, and low hysteresis (typically better than 0.01% of full scale output for each). The maximum linearity error of these sensors is ±0.25% of full range output.

The Macro Sensors SQ 1250 Series of heavy duty LVDTs were developed specifically to measure position or motion in mill-type hostile environments. These rugged and reliable contactless sensors, available in measuring ranges from ±0.50 inches to ±10.00 inches, have their electrical assembly totally encapsulated within a heavy duty aluminum housing, with their electrical connections made to screw-terminal style barrier strips. This complete encapsulation of SQ 1250 Series LVDTs allows them to withstand the high shock and vibration levels typically encountered in mill environments and permits them to meet the IEC IP-64 sealing standard against the intrusion of splashed water and other liquids.

Macro Sensors’ HSAR 750 Series of 3/4 inch (19 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 HSIR 750 Series of 3/4 inch diameter, loop powered 4-20 mA LVDT position transmitters is designed for a wide range of position monitoring and feedback applications. These rugged, hermetically sealed sensors are 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 input/output connections are made through a sealed radial connector located near one end. A mating connector plug is supplied with each unit.
