TM142 tension signal amplifier panel is designed with an interface that is convenient for quick zeroing and calibration, and a full-color display screen is used to display the left tension, right tension and resultant force. It also has RS485-RTU and CAN communication functions. RTS series sensor is designed as a movable shaft structure, with self-aligning ball bearings, which can compensate for the mechanical error caused by shaft installation to avoid the impact on measurement; Easy disassembly installation design allows easy installation and replacement of measuring rolls during continuous material production. Coil correction controller EC100 adopts high resolution LCD display, making the parameters and running status more intuitive, detection real-time waveform display, high-end UI interface design, motor driver can withstand high intensity impact load, using DC stepper motor and precision ball screw, fast execution and high precision, The ultrasonic sensor ESU16C, as a heel edge
