NC-3 torque measuring instrument

Case Presentation

NC-3 Torque Measuring Instrument—Product Background


NC-3 torque meter is used in conjunction with various range of magnetoelectric phase difference torque sensors (such as NJ torque sensors) to accurately measure the torque, speed and power of various power machinery.
NC-3 torque meter adopts high-speed digital signal processor (DSP) and large-scale programmable logic chip (CPLD) to form a simple and efficient data acquisition and processing system. The unique design and advanced surface mount technology greatly improve the reliability of the system The hardware has two-level watchdog function to ensure that the system can be reset in time when abnormal; the instrument supports forward and reverse two-way zeroing, single-point or multi-point zeroing. The communication function has been strengthened, you can choose RS232/485 or CAN communication mode to make the communication with the computer easier, flexible and fast. Can adapt to the habits and preferences of different software engineers. It can adapt to different industrial scenes.
The instrument uses a large-screen dot-matrix LCD display and a simple keyboard to provide a friendly man-machine interface.
