Electronic torque detection
■ The cut-off torque can be set bidirectionally (forward/reverse) independently in steps of 1%.
■ The electronic torque detection device includes an effective power detection circuit, a motor angular velocity detection circuit, a control circuit and a CPU microprocessor. During operation, the microprocessor continuously detects the effective power and angular velocity of the motor and calculates the actual torque and compares it with the preset cut-off torque. Once it exceeds the limit, the CPU immediately cuts off the motor power supply and outputs a fault alarm message to achieve over-torque protection. The actuator motor will not burn out due to stalling, and the valve will not be damaged due to over-torque of the actuator.
■ Non-contact torque detection, no mechanical torque switch is required, no mechanical wear, and long service life.
■ The output torque can be simply and quickly set using an infrared setter without opening the cover.
■ It is not affected by factors such as temperature and voltage fluctuations, has high accuracy, and can fully meet the reliable protection of on-site valves.
Absolute coding technology
■ The absolute encoder used in the electric actuator can operate continuously and is 100% repeatable. It can provide accurate position signals to the processor even without power or battery power.
■ Single-turn uses 12-bit counting with an accuracy of 0.08
■ Multi-turn uses 6-level gear counting, which can reach 4096 turns (the count value is unique in the 4096 rotations of the drive sleeve)
■ The redundant circuit of the encoder can ensure normal operation even if 50% of the components fail
