Vertical EYM

Electronic Yarn Meter™

designed to work in a vertical orientation

 

Nancy's Knit Knacks is pleased to announce the introduction of another version of its electronic yarn meter

 

 

This unit is based on our standard Electronic Yarn Meter. It enables a user to measure yarn from cone on the floor.

It includes the remote meter.

 

Accuracy of Measurement

The EYM utilizes a high tech electronic optical encoder system combined with a custom designed microprocessor controlled circuit card. The unit divides each inch of yarn into 28.4 equal segments and then performs its calculations to measure either yards, meters, or weight. At the maximum speed of the unit (up to 10 yds per second) under normal use, this means that over 11,000 data signals are interpreted by the computer every second.

The end result: 0.001% error rate for meters (that is 1 meter per 1,000 meters measured) and 0.003% error rate for yards (that is 3 yards per 1,000 yards measured). The reason that Metric measurements are more accurate is because there are 100 centimeters in a meter and only 36 inches in a yard. This finer degree of resolution for metric results in a more finely tuned measurement. When compared to mechanical meters under the best of circumstances (which have error rates of approx 5% or more) that means that the EYM measures from 17 to 50 times more accurately and much more consistently than the typical mechanical fishing meter based systems.

Accuracy also has much to do with the method by which the yarn drives the measurement wheel/pulley. In the fishing meter type systems, the yarn engages a very small amount of the pulley's surface (20-30 degrees of contact). In the EYM, the contact area is 180 degrees approx.. Furthermore, the EYM utilizes a large diameter drive wheel which has a soft foam rubber type surface which ensures that the yarn will not slip over the surface. Yarn slippage is the Achilles heel of the mechanical fishing meter systems and we made sure in our design of the EYM that yarn slippage would not occur.

The last element of measurement  accuracy has to do with the mechanical axle that both supports the structure and connects the drive wheel with the optical encoder. The EYM's drive shaft utilizes two ball bearing units to ensure trouble free and friction free rotation. This design does not add any significant drag or tension to the yarn while it is being measured.

Yarn Type

The EYM has a 5/16" diameter orifice on its yarn guides. As long as your yarn will fit through these openings, you will be able to measure it with the EYM. This includes ribbon yarns and other novelty yarns.

 

Yarn Direction

This version sis designed for vertically fed yarn

 

Power

The EYM utilizes standard 100-240 VAC 50-60 Hz power. This makes it capable of being used anywhere on the planet.  The unit will go into Sleep mode after 5 minutes of inactivity. The user can bring it out of sleep mode by simply pressing the Reset button.

 

Warranty

1 year limited warranty for both consumer and commercial users

Bob's Commentary

With the EYM, you can do the following:

Measure yards in tenths of a yard (3.6" increments)

Measure meters in tenths of a meter (10 centimeter increments)

Measure* the weight  of your yarn in ounces (even hundredths of an ounce)

Measure* the weight of your yarn in grams

* Weight is measured by the "weight equivalency method." In this method, we take the user entered weight and length for the yarn and create a relationship between weight and length so as the unit measures length, it is also calculating weight. This is a Nancy's Knit Knacks' exclusive feature.

Enter a qty of yards or meters (or ounces or grams) that you want to wind into a ball and have the meter stop the ball winder at that point! This capability has never existed in the commercial or consumer market. It is as automated as it gets.

What about accuracy?

We break down each each rotation of the measuring wheel into 200 segments. Since the wheel is about 7 inches in circumference that means that we are measuring the yarn in .035" segments. Therefore, each segment is about 1/7 of a quarter inch. Plus we are doing it fast (at speeds up to about 15 MPH).

Our mounting system allows the user to mount the meter between their floor mounted cones and their skein-winder or cone winder.

Don't have our motor driven skein-winder system? Don't worry, the meter's electronic tone will sound when the meter measures the qty that you want to measure.

Plus you can add our IPS™ system which will shut down your motor-driven system automatically. We are the only company on the planet that can measure your yarn and control your motor driven device and turn it off automatically when the meter has measured the quantity of yarn that you need.

How sturdy is the unit?  Will it hold up?

It has an aluminum housing for both strength and weight reduction.

Custom designed electronics are enclosed in the housing and fully grounded to guard against static issues.

Mechanical components include a custom designed shaft supported by ball bearing mounts and slip proof wheel surface that will not allow your yarn to slip over the wheel. Plus our innovative post mounting system used to control elevation of the meter head will amaze the engineers in your company/family.

Hardwood construction with stainless steel components and rock solid old-style American engineering provide you with a product that you can be proud of. We certainly are and we know that you will be very impressed with our electronic metering system.
