Separate Free Core AC Operated LVDT Position Sensors

Macro Sensors’ LVDT CD 375 Series of 3/8 inch (9.5 mm) diameter AC-operated LVDTs are small size contactless linear position sensors for both OEM and end user applications. They are available in full scale measuring ranges from ±0.025 inch (±0.63 mm) to ±1.0 inches (±25 mm) and offer 50% larger core-to-bore radial clearance, 0.012 inches (0.3 mm), than similar size units from competitors. The low mass of their cores makes these miniature LVDTs well suited for high response dynamic measurements. CD 375 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 a CD 375 sensor is ±0.25% of full range output, using a statistically best-fit straight line derived by the least squares method.

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.

Macro Sensors’ HLR 750 Series of 3/4 inch diameter high reliability LVDT position sensors are specifically designed for use in gas turbine environments. Rated for operation to 300°F (150°C), these hermetically sealed AC-LVDTs are listed for Class I, Division 2, Groups A, B, C, D and Class I, Zone 2, Group IIC hazardous locations by Underwriters Laboratories.

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.
