Checkline LMC [LMC] Yarn Length Meter, Measures Centimeters, 0 - 999,999 cm. Checkline LMI / LMC Yarn Consumption Meter accurately measures the amount of yarn being fed from a textile machine feeder to a take-up device during one or more cycles or rotations of the machine cylinder. LM units are ideal for comparing yarn consumption from feed to feed and machine to machine on circular and flat bed knitting machines, and for other textile processes where yarn length is to be accurately measured. Two LM types are offered: Models LMC and LMI manual type, where operator actuates and deactivates the measuring system after one or more operation cycles. (LMC is calibrated for centimeters; LMI is for inches). The consumption per cycle is then determined by dividing the total yarn consumption by the number of cycles or revolutions. Models LMC-S and LMI-S magnetic sensor type, where operator pre-sets number of cycles or revolutions (0-99) for the measuring period, eliminating the need to visually count the number of cycles. A small magnet is affixed to the rotating or moving part of the machine while the sensor is mounted on the frame. Each time the magnetic passes the sensor it actuates the instrument’s electronic counter.
