Tension Meter MST

4 Tension ranges available
from 1 - 200.0 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 9 m/min

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

Tension meter MST has a coloured, backlight TFT display with 3 different display modes
– numeric
– numeric with live bargraph
– numeric with graph (time-tension)

The display rotates in 90° steps for better reading

Tension meter MTS can be connected to a PC using the USB interface to monitor readings constantly on a PC

Memory for 60.000 readings

5 different memory modes can be selected by the operator:

  • Mode S: only statistical values per series are displayed
  • Mode H: storage of the X-Y-diagram for reviewing after finishing a series of measurement
  • Mode C: continuous logging over a user set time and max. 999 series of measurement (2 Hz)
  • Mode F: as C with higher sampling rate (200 Hz)
  • Mode D: storage of single readings and statistic 

Model MTS can be connected to a PC with the USB cable. With the software SW-TI3-M »Tension Inspect 3« readings can be displayed, statistically analysed and saved. For more information see “Optional Accessories”[/rt_icon_list_line]
Selectable units of measurement: cN, g, N and lb

Very high data sampling rate (internal 1 kHz)

Storage of MIN, MAX, last reading, average and standard deviation per measuring interval

User-set MIN and MAX alarms with indication of TFT display if reading is out of limits

Adjustable electronic damping for better reading when tension fluctuates

Automatic “Zero-Setting” in each measuring position using a special sensor technique

3 separate calibration material memory locations for custom calibrations

Calibration adjustment for fine tuning of the calibration if material differs from the used calibration material

Menu set-up in English or German language

Standard Features

Battery or mains operation

Rugged aluminium housing

Easy to operate

CE approved (tested for electromagnetic compatibility)

Certificate of Compliance with the order 2.1 according EN 10204 is included

Optionally available: Inspection Certificate 3.1 according EN 10204 with calibration report

Seam with correct and incorrect adjusted thread tension

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.
