Yarn Length Meter LMC-V, LMI-V

Measuring range 1 - 999999 cm or Inch

Electronic length meter to measure the yarn consumption of a single yarn feeding system for one or more machine cycles of a circular knitting machine

Measuring time can be determined with the start/stop signal of the meagnetic sensor or manual

Categories: Yarn Length Meter for Knitting Industries, Speed and Length Meter

Special Features

Yarn length meter LMC-V for measurements in cm and LMI-V for measurements in inch

Sensor controlled unit with a sensor (mounted on machine frame) and magnet (mounted on rotating part) for automatic start/stop signal

Precision, ball-bearing mounted wheel is recessed into an adjustable slot on the rear side

Material slip is eliminated by maximum enlacement of material (approx. 120°) with rubber coated wheel

Sketch of mounting a yarn lengthh meter LM series

It is stationary mounted between filament break monitors and filament guides using the supplied magnetic base.

Standard Features

Easy to operate

Includes magnetic base for quick installation on the machine; it is stationary mounted on the zylinder ring between filament break monitors and filament guides

Battery operated length meter

Operation

In ”Auto” mode a permanent magnet is mounted to a revolving part of the machine. The sensor supplies the start/stop signal. The predetermined number of revolutions (from 1- 99 rev. set on the rotary switches at the front side) are counted and the cumulated yarn consumption is displayed.

In ”Basic” mode the unit works without external sensor; Operator determines measuring time by pushing start/stop button.

Advantage of yarn length meter LMC-V and LMI-V use:

Continued measuring of the yarn consumption of all knitting feeds ensures uniform stitch lengths and hence homogeneous fabric structure.
Predetermined fabric specifications can be reliably maintained and repeated.
The quantities of each type of yarn which are required for producing particular fabrics can be simply and accurately calculated.
The use of LM ensures the same fabric quality, respectively structures can be produced on different machines in the same quality.
