With the digital system for incremental encoders meM-INC from BMC Messsysteme GmbH (bmcm), signal pulses can be counted and frequencies measured via the USB interface.

Incremental encoders convert linear or rotating position changes into a digital signal. They are used as sensors for distance and angular measurements. Basically, their working principle consists in periodically arranged segments on a measuring stick or a disc producing electrical pulses during motion. The actual position is determined by the number of increments passed.
