【English Version】
The DT2235A is a precision contact-type tachometer and linear speed meter engineered for industrial manufacturing, equipment maintenance, and scientific research applications. Utilizing direct-contact measurement technology, this device captures rotational movement through physical transmission, delivering authentic operational data reflective of actual machinery performance.
Equipped with high-sensitivity sensors, the instrument covers a broad measurement range from 5 to 99,999 RPM for rotational speed, with automatic linear speed conversion (0.1~1999.9 m/min) based on customizable roller circumference. Its triple-roller contact mechanism minimizes slippage risks, while the adjustable spring pressure system accommodates various shaft diameters. The 2.5-inch LCD display provides real-time monitoring with MAX/MIN value recording capability, enabling effective detection of operational fluctuations.
User-centric features include a data hold function for measurement documentation, auto power-off for extended battery life, and backlight illumination for low-light environments. Constructed with industrial-grade ABS housing featuring IP54 protection and anti-slip grip, the device maintains reliable performance in challenging workshop conditions.
Ideal for motor speed verification, conveyor belt monitoring, and machine tool spindle analysis, this instrument excels in environments where non-contact measurement proves impractical, such as oily or dusty workspaces. The included carrying case contains three interchangeable measuring wheels (20mm/35mm/50mm circumference) for versatile application scenarios. Through optimized mechanical transmission and digital processing algorithms, the DT2235A achieves measurement accuracy while minimizing interference with measured equipment, establishing itself as a dependable solution for dynamic parameter acquisition in industrial settings.
