Mechanical yarn tensiometers require considerable free space for measurements to be taken along the running yarn. This may prevent measurements at desirable spots. Small yarn tensions ( below a few cN/ponds ) cannot be measured at all, yet just these tensions quite often play an important part in the processing of synthetic fibers.

Quick tension changes due to the new high speed machines, travelers on a ring spinning and twisting frame, variations in balloon size, ring rail displacements, yarn tensioners or brakes, the shape of bobbins, machine drive parts, yarn irregularities etc., cannot be measured by a mechanical device. Moreover, a direct recording of smallest yarn tensions and short-time peak tensions is not possible.

In order to overcome these difficulties, the ROTHSCHILD ELECTRONIC - TENSIOMETER R - 2000 was developed. Most, if not all measurements which previously could not be carried out, can now be undertaken. This instrument is of special value in measuring and recording tensions of standard yarns, synthetic yarns, elastomer yarns, ribbons, tows, glass fibers and wires.

Apart from general use in production control, textile machinery designers and engineers from research and development laboratories find this instrument with its multitude of applications an indispensable tool for their work. By using the ROTHSCHILD ELECTRONIC-TENSIOMETER considerable improvements to the product quality and production efficiency can be expected.

MEASURING HEADS

The measuring heads are an integral part of the instrument with a large choice of tension sizes for many different applications available. The small dimensions ( Ø 30 mm ) of the measuring heads facilitates measurements by the ROTHSCHILD ELECTRONIC - TENSIOMETER at almost any location. The yarn is not deflected from its path and its tension is not influenced by any outside forces.

Special measuring heads allow measurements in acid baths and humid surroundings ( e.g. viscose baths, etc ) and on glass fibers.

MEASURING CHANNELS

- All tensions are recorded analogically and digitally
- Maximum / Minimum / Average values are continuously recorded and displayed on the monitor, while resetting is possible at any moment.
- Optional setting of galvanometer with afterglow to follow tension variations.
- The ELECTRONIC - TENSIOMETER R - 2000 has two separate measuring channels.

This feature offers the following:

A ) MONO - measurements from Channel 1 – or – Channel 2 working from Measuring Head MH1 – or – MH2

B ) DUAL - simultaneous measurement on separate positions using both channels and the 2 Measuring Heads MH1 and MH2.

MEASURING APPLICATIONS

The application range of the ELECTRONIC - TENSIOMETER in the textile industry is practically unlimited. It is now common practice to take measurements on the following machines:

- Spinning machine
- Winders
- Ring spinning frames
- Twisting machines
- Looms
- Texturizing machines
- Warping machines
- Flat- and circular knitting machines
- Sewing machines e t c.

The list of professionals and production industries where the ELECTRONIC-TENSIOMETER is an important instrument to keep up quality, productivity and product-development, is long and just a few are mentioned:

- Textile machinery designers
- Synthetic fiber producers
