Tension Meter MST

3 Tension ranges available
from 1 - 500 cN up to 1 - 2000 cN

For fibers up to 2000 tex

Electronic yarn tension meter with motorized take-up fixture for measuring and adjusting the tension of sewing machines to get best and highest quality stitched seams. Therefore e. g. yarn breaks can be adjusted under constant conditions (speed of the thread).

Tension meter to control the tension at sewing machines as well as the take-off tension of shuttles

CE mark

Special Features


Electronic yarn tension meter MST  with motorized take up with tension range up fixture

The electronic tension meter ETX is the basis of this instrument

Motorized take-up fixture to have constant speed of the thread 8 m/min

Storage of AVG, MIN, MAX and PEAK tension values of a user set time frame. These values can be recalled in the display

Adjustable electronic damping for better reading when tension is constantly fluctuating

Vacuum base for positioning the unit on the work plate when tension is measured at the sewing machine

Special fixture to determine shuttle tension

Output signal:
– analog 0 – 2 V DC
– digital RS-232

The tension meter MTS can be connected to a PC using the RS-232 interface to monitored readings constantly on a PC

Memory of max. 4000 displayed tension values split up to 255 series of measurements and statistics (Last, AVG, MIN and MAX of displayed values, MIN-PEAK and MAX-PEAK are values measured within a measuring frequency of 100 Hz)
Content of the memory

4 different memory modes can be selected by the operator:
– Mode S: only statistical values per series are displayed
– Mode L: statistics plus 10 displayed values of each series of measurement
– Mode C: statistics plus 4000 displayed values arbitrary split up to 255 series
– Mode F: as C plus higher sampling rate of 100 Hz = values/s

besonderheiten-pc-verbindungModel MST can be connected to a PC with the RS-232 cable. With optional available software SW-TI3 »Tension Inspect 3« readings can be displayed, statistically analyzed and saved. For more information see “Accessories”

Tension meter MST on vacuum base beside a sewing machine

mst thread good and not good

Left: Seam with correct adjusted thread tension
Right: Too much threat results in not sufficient linkage of the threat the the used material

General Information:
Besides strength and the kind of stitch the tension of the upper and under thread is important for the solidity and the image of the seam. Tension determines the stitching length.
