Working principle and introduction:
It has five digit display, ratio display, ratio output function, programmable setting function, and upper/lower limit control function. Strong adaptability of electrical appliances, equipped with sensor power supply, no need for batteries, data can be saved for ten years. The 722 series rate electronic counter can handle both fast and slow pulse sequence processes, and is suitable for various situations that require measurement and display of time related variables. It comes with models with limited values, as well as functions for numerical comparison and output signals. Applied to speed control systems and power generation systems for automated assembly lines.
