Electronic Twist tester Branca 61S measures the exact twistings number for monofilament yarns plied yarns, multi-level yarns, Open End yarns

The apparel is designed to determine the twistings no. per meter (TPM) or twistings. no per inches (TPI) of various types of yarns as e.g. single, double, multi-level and Open End and others.

Electronic twist-tester 61S is in compliance with Standard UNI 9069, UNI EN ISO 2060, ISO 2061, ASTM D-1423, ASTM D-1422 and others

Twistings no. reading resolution has been enforced by the highest measure accuracy at 0,1 twist and yarn sample can be tested at different lenghts from 0 to 50 cm in standard versions or until 1 or 2 m for special models mainly used for tyre cords application.

The electronic twist tester 61S is easy to use thanks to the user interface with HMI Touch Screen that allows to select the STANDARD software version ideal for various yarn types:

SINGLE	single yarn test - untwist-retwist of single yarns in SZS or ZSZ (UNI 2061);
DIRECT	direct counting method - only untwist of yarns according to ASTM Standards;
DUAL	test method suitable for double or plied yarns;
SCHUTZ	suitable for Open End yarns according to the 2nd Appendix New “double test check” worked out by Messrs. M.KUENY, H.LE CHATELIER and R.A. SCHUTZ;
MANUAL	motor control digitally commanded by the operator and real time read-out of real twistings;

Additional test methods are implemented only in PRO software version:

SLIPPAGE	test method used to determine when yarn fiber slip off applying different pretension weights;
MULTI-LEVEL	test method suitable to determine the twistings no. of plied yarns up to 5 yarn levels;
GUIDED ANALYSES	operator led by the indications on the screen and test indexing, can perform multiple analysis on Single, Direct Counting, Dual, Multi-level yarns following instructions shown on display step by step;

The test report is printed with ASCII printer supplied on request, where the operator can input data and notes as additional data, e.g.:

Company name;
Address
Country
Tension applied to yarn in grams;
Material
Sample no.
Notes;
Test results espressed in TPM or TPI;
Operator signature;

Test report includes additional info about:

Starting yarn untwist direction: S or Z;
Yarn length, expressed in cm or inches;
Saved memory up to 20 results per test method;

Other statistical evaluations:

Minimum;
Maximum;
Average;
DELTA (Max-min);
Coefficient of Variation (CV%);
Standard Deviation (ST.Dev%);

Saved results are expressed both in TPM (twist per meter) or in TPI (twist per inch).

The measure units are indicated on test report.

During the test, the HMI touch screen shows data and evaluation data, e.g.:

Motor speed in rpm;
Number of twist on real time;
Test index (1..20);
Direction of twist (S/Z or Z/S);
Operation commands e.g. start, stop, repeat, etc.);

Application software TWIST4.0: for PC use through USB serial port communication, that allows to do automatic statistical evaluations on test results, generation of trend graphs, macro plugins and math formulas;
