ZEF ZED
Digital Thread Tension Meter - Accurately Measures Micro Thread Tension
The principle of the digital wire tension meter is that the traveling wire passes through three V-shaped wheels. The load testing function of the central V-shaped wheel converts the analog tension signal into numbers and presents them on the display screen. The ZEF wire tension meter can be used in a small space to check the tension changes of the spinning yarn, the numbers on the LCD screen can be automatically rotated (90 degrees) in any direction for easy reading.
Features
Tension ranges from 0.5 - 200 cN to 1 - 200 cN
Cost-efficient electronic tension meter for measuring low tensions of fibres, threads and fine wires. Hand-held device with slim filament guide and small guide rollers for limited access space
Tension meter ZEF with easy to read LCD display
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 / Automatic “Zero-Setting” in each measuring position using a special sensor technique / 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 / 3 separate calibration material memory locations for custom calibrations Menu set-up in English, German, Spanish and French language / Slim filament guide with small guide rollers – ideal for limited access space / Simple, trouble free operation Filament guide and unique roller shifting mechanism ensure easy acquisition of the running material / Light weight hand-held unit
