Rotational speed ratio meter
■ A rotational speed ratio meter, connected to sensors with various forms of output, such as a pulse output type of rotation sensor, rotary encoder, or photoelectric sensor, which calculates speed using inputs from two such sensors.
■ 6-digit and 13-digit, two-level, high brightness LCD display (red and green)
■ CAN output supported.
A high-precision, highly-functional digital panel meter with a built-in function for measuring the rotational speed ratio.
The model configuration for this instrument is as shown in the figure below.
The model is left-justified when option “No” was selected.
Multiple options cannot be chosen from options in the same group.
Two different types can be selected out of digital output, contact output, and communication.
