The compact WTM:003 Warp Tension Meter has been developed to measure the tensile forces in warp threads. The combined forces of a warp of 50 mm in width is measured by a measuring head with a 100mm roller.
The results are shown on a separate display instrument. Storage of AVG, LAST, MIN, MAX, PEAK-MIN, PEAK-MAX tension values during a measuring period can be set by the operator.
Test Method
Swivel the lever towards the handle to move the measuring roller downwards. Hold the measuring head over the yarn group, so that it runs parallel to the measuring feeler and the support rollers. Guide the measuring roller through the yarn, turn the measuring head by 90° and swivel the lever forwards, away from the handle, to move the measuring roller upwards into the measuring position.
Key Features

✔ Portable
✔ Easily engaged and disengaged

WarpTensionMeterLTF2021 (pdf)
DownloadA range of 6 models with different ball sizes and working faces, the slightly curved working face fits to small bobbins, and the flat working face for bobbins and other packages with diameters over 400 mm. The ball shaped indenter prevents damage to bobbins with three different sizes:
2.5 mm diameter ball for closely wound bobbins of synthetic, finished yarns and filaments.
5 mm diameter ball for loosely wound bobbins of synthetic fibre yarns and closely wound natural fibre yarns and threads.
10 mm diameter ball for very loosely wound bobbins of thick yarns such as carpet yarns.
The spring-loaded outer ring of the main body of the tester is pressed downwards until the edge of the ring reaches the red mark, this ensures a constant pressure and prevents measuring errors between operators.
Key Features
✔ 6 different models
✔ Constant pressure system
✔ Ball-shaped indenter
✔ Optional memory pointer

DownloadAccurate measuring device to determine the linear density of yarn.
The Wira Yarn Count Balance is the ideal device for the analytical testing of yarn count.
Readings can determine the linear density (mass per length) of yarn skeins and the GSM (mass per sq m) of fabrics. The Wira Yarn Count Balance gives the results in Tex, dTex and other yarn count systems such as Metric count (Nm), English count (Ne), English cotton count (Nec), Denier (Td), etc.
This apparatus allows the user to obtain results without operating on external devices e.g. calculator, excel.
Storage memory of up to 100 results. Portable or Lab versions available.
