Digital speedometer SMD6-1S/220V
V=(0.001 ÷ 999.999 m/s), Us=220Vac, 95x49x113mm
The digital SMD6-1S/220V speedometer is a microprocessor device with a 6-digit display and serves for measuring linear speeds in the range from 0.001 to 999.999 m/s. By setting a conversion coefficient "C" the received electrical impulses in the speedometer are converted into a linear speed. The speedometer receives a signal from sensors and switches type "NPN" connected to his input. The device is designed for installation in a dashboard (panel montage).
The digital SMD6-1S speedometer is meant for measuring the linear speed of cloths, pipes and other materials, that in their movement whirl a check-roller, from which by certain sensor electric impulses are sent to the input of the speedometer. For counting the speed, in the memory of the speedometer is given the coefficient "C", which presents the real distance between two impulses in the input of the speedometer. The coefficient “C” is assigned in millimeters.
