MST
Tension Meter

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

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

STANDARD ACCESSORIES

305002 – Vacuum Base

Vacuum base for fast, save placing the measuring device at the working base beside the sewing machine. The tension meter MST can be horizontal positioned in exactly measurement position. Adjustable height for measuring position above working plate 125 to 210 mm. To save the vacuum base on the working plate, the rocker must be activated.
