The digital SMD6-2M/12-24V speedometer is a microprocessor device with a 6-digit display and serves for measuring linear speeds in the range of 0,01 to 9999,99 m/min. By setting a conversion coefficient "C" the received electrical impulses in the speedometer are converted into a linear speed. The speedometer has two output relays and there can be set two limit values "V1" and "V2" in reaching of which the relevant output relay switches on. 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 SMD6-2M speedometer is meant for measuring and controlling the lineal speed “V” 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 centimeters. Two speed limits V1 (down) and V2 (up) can be set, upon reaching which the relevant output relay is activated.

Short description

The SMD6-2M digital speedometer is an electronic device used as a means of automation production processes. It is used to convert the incoming electrical pulses into a linear speed (m/min). The speedometer visualizes the measured speed on a digital display and when a certain limit value is reached, turn off or on the electrical circuit in which it is included.
