Description
This is a description of a HC-020K double speed measuring module with photoelectric encoders. It has a wide voltage range (4.5-5.5 volts), high resolution (0.1 degrees), and short response time (10 milliseconds). It can measure the rotational speed of a motor with a black encoder (measured specification is related to the encoder), and can be used to measure the pressure drop and current in a launch tube.
Wide voltage, high resolution, short response time, switch output; Can test motor's rotational speed w/ black encoder (measured spec. is related to the encoder, the inner diameter of D type encoder that provided is 4mm, can be used for motro output shaft w/ 4mm diameter, which is TT motor we matched, yellow shell and white axis. Working voltage: 4.5~5.5V; Launch tube pressure drop: Vf=1.6V; Launch tube current: If
