High-Precision Automated LVDT Calibration Platform SYCL500
Micron-Level Accuracy, Fully Closed-Loop Control, and Digital Calibration Solution
Product Description
1. Product Overview
The SYCL500 is a high-precision, custom-engineered calibration platform designed for LVDTs (Linear Variable Differential Transformers) and other high-precision contact displacement sensors. The system is centered on the L501 motorized linear drive unit, integrated with a high-resolution linear encoder, and combined with a precision mechanical transmission and closed-loop motion control. This configuration enables fully automated sensor calibration, linearity verification, and repeatability testing.
Compared with conventional manual calibration devices, the SYCL500 offers a 200 mm travel range, 0.1 μm displacement resolution, and ±0.2 μm bidirectional repeatability, along with superior coaxial stability. The platform meets the stringent micro-displacement measurement and control requirements of research laboratories, precision manufacturing, and metrology laboratories, providing a highly traceable displacement reference standard.
