Non-invasive Design
The High Torque Multi-Rotation Actuator BD120-C6 adopts advanced non-invasive design to make parameter setting safer and more convenient. Operators can complete calibration, query and adjustment through knobs or infrared programmers. There is no need to open the shell during commissioning, which avoids dust and moisture entering the interior. Magnetic control and built-in Hall sensors ensure stable signal transmission. The design greatly improves the reliability of the control system and prolongs the service life of electrical parts. Non-invasive operation also reduces maintenance difficulty and extends the overall service life of the equipment. It keeps the internal structure clean and stable even in harsh outdoor environments.
Absolute Encoding Position Sensor
The High Torque Multi-Rotation Actuator BD120-C6 uses a multi-turn absolute encoding position sensor to achieve high-precision position detection. Specifically, the sensor adopts non-contact measurement technology, which features high stability and long service life. In addition, it can keep accurate valve position data after power failure without battery support. Furthermore, the component provides real-time and reliable position feedback for the control system. Moreover, it supports automatic stroke self-tuning and improves the overall control accuracy of the actuator. Meanwhile, stable position signals ensure consistent movement and avoid position drift during long-term running. Therefore, this sensor becomes a core part to guarantee precise and reliable valve control.
