●ZOOMLION 1021406027 Speed Sensor Technical Support
●The 1021406027 Speed Sensor ( Датчик скорости роторной буровой установки) serves as a heavy-duty rotational speed telemetry unit on compatible ZOOMLION rotary drilling rigs and foundation construction equipment.
●Material number 1021406027 is mounted on the rotary power head hydraulic drive motor, main winch hoist drum reducer, or slewing reduction gearbox. It non-contactually senses passing gear teeth pulses under severe vibration, outputting high-precision square-wave frequency signals to the drilling rig programmable logic controller (PLC) and cab touch-screen monitor. This enables accurate drilling rotational speed measurement, torque-speed optimization, line speed telemetry, and precise depth control during foundation piling operations.
●Verify mounting thread dimensions, probe insertion depth, electrical connector pin layout, and signal pulse frequency curve prior to order confirmation.
