Product Using Principle
ABB QHFT201 YL681001-AB filters and amplifies the rotational speed signal input from the sensor through internal circuits, and subsequently converts the analog signal to a digital quantity through an analog-to-digital converter (ADC), which is processed by a microprocessor to generate a standardized output signal. Some models may support protocol conversion to communicate directly with the host computer. The core mechanism is to convert the physical rotational speed into an electrical signal and adapt it to the input requirements of the control system.
