Price 59.85 EUR no VAT

The CMD6-3R/12-24V digital revolution counter is a microprocessor device with a 6-digit display and serves for measuring revolutions in the range from 3 to 60'000 rpm. The rev counter is reversible and has two inputs "A" and "B". It operates in combination with two sensors type "NPN" or one sensor type "NPN" with two dephased outputs (OVM1-18.24.F). The revolution counter indicates the rotation direction of the shaft by means of two LEDs located on the front panel. The tachometer is designed for installation in a dashboard (panel montage).

FEATURES

The CMD6-3R digital revolution counter is used to measuring revolutions of rotation of axles and other turning objects, and shows the direction of their rotation. The rev counter is designed to work with NPN type sensor with two dephased outputs "OVM1-18.24.F" (encoder type) or with a combination of two NPN type sensors. For the correct work of the system “revolution counter - sensor" is necessary to enter one impulse from the sensor to the revolution counter for one full rotation of the object.

Short description

The CMD6-3R digital tachometer is an electronic device used as a means of automating production processes. Serves to convert the electrical impulses received to it in revolutions (rpm). The main purpose of the tachometer is to visualize the measured revolutions on a digital display and to indicate the direction of rotation of the shaft.
