Overview
The CGK-II dynamometer control instrument is used with compatible torque sensors and speed sensors to measure and control engine torque, speed, and power parameters.
The instrument uses a digital incremental PID control algorithm for high control accuracy; torque and speed settings use a photoelectric digital encoder, which is contactless, wear-free, and long-lasting; input, output, and power are all isolated, with high anti-interference capability.
It uses advanced CAN fieldbus technology and an advanced "masterless" structure, making system construction and expansion very convenient.
The instrument has a built-in character library, and with the LCD display and simple keyboard, human-computer interaction is very easy. Menu and option operations are simple and clear.
