Import Displacement Sensors Lvdt-Dea200 — Buy in wholesale FOB from Supplier in China

The LVDT-DEA200 is a linear variable differential transformer displacement sensor designed for precision measurement in industrial automation and power plant control systems. It features a measuring range of 200 mm, a linearity error of ±0.25% F.S., and operates with an excitation voltage of 2.5 Vrms to 10 Vrms. The sensor housing is constructed from stainless steel with an IP67 rating, suitable for harsh environments including high vibration and moisture exposure. Output is a differential AC signal proportional to core position, compatible with standard signal conditioning modules.

Typical core materials for this class of LVDTs are nickel-iron alloys with low hysteresis and high magnetic permeability, ensuring repeatable performance over extended cycles. The sensor’s coil assembly is potted with epoxy resin to resist thermal drift and mechanical shock. While the listing does not specify the exact core diameter or coil winding pitch, standard industrial LVDTs of this type typically use a 6 mm to 10 mm core diameter with a 0.05 mm to 0.1 mm air gap tolerance. The sensor is not rated for explosive atmospheres and lacks intrinsic safety certification.

This sensor is commonly used in turbine blade position monitoring, boiler feedwater valve control, and hydraulic actuator feedback loops in thermal and nuclear power plants. Buyers include engineering firms managing plant upgrades, OEMs of industrial machinery, and maintenance contractors servicing heavy equipment. Packaging is in anti-static foam-lined boxes, with 1 to 5 units per carton. Lead time is not stated; buyers must confirm availability with the supplier. Incoterms are not listed, but FOB Qingdao is typical for exports from Sichuan.

Deyang Dongfang Yoyik Engineering Co., Ltd. is based in Jingyang District, Deyang, Sichuan, China. The company positions itself as an integrated supplier of power plant instrumentation, offering both sensors and associated control components. Its profile indicates technical support capabilities for installation and maintenance but does not specify years in operation, employee count, or annual turnover. The supplier has not provided certifications such as ISO 9001 or CE, nor has it listed any verified client references.

The supplier’s listing includes a broad catalog of spare parts for power generation equipment, suggesting experience in the thermal and nuclear plant maintenance market. Response rate and average response time are not available, indicating limited or no active engagement on the platform. No factory photos, production capacity figures, or quality control processes are disclosed. Buyers should treat this as a trading entity with engineering support, not a verified manufacturer with published quality documentation.
