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 ±2.0 inches (±50 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.
