Checkline - Limited Access Digital Tension Meter with Color LCD Display, ETB - ETPB
5 Ranges
0.3 - 100.0 grams (or cN)
2.0 - 200.0 grams (or cN)
2.0 - 500.0 grams (or cN)
3 - 1000 grams (or cN)
3 - 2000 grams (or cN)
For fibers up to 500 tex and Cu wire Ø 0.17 mm
The Checkline ETB / ETPB tension meters are designed for accurate measurement of tension on fine wires, yarns and fibers. Rollers or Ceramic Pins are mounted at the end of long "fingers" permitting the user to measure tension with limited access space or when several lines are closely spaced such as on a warp sheet. Five (5) measuring ranges are available with a maximum capacity of 2000 grams or cN.
New features include Color, backlight TFT-display with 3 different displays modes: numeric, numeric with live bargraph, numeric with graph (time vs tension). The display auto rotates in 90° steps for optimal visibility regardless of the position of the tension meter.
ETB models feature miniature high speed ball-bearing-mounted rollers for material speeds up to 2000 m/min
ETPB models feature non-rotating ceramic pins for material speeds up to 6000 m/min
Features
- Coloured, backlight TFT-display with 3 different displays modes: numeric, numeric with live bargraph, numeric with graph (time vs tension)
- The display auto rotates in 90° steps for better reading
- Automatic Zero-Setting in each measuring position
- Selectable units of measure; Grams, cN, N and Lbs
- High data sampling rate to catch short duration peaks (1 kHz)
- Storage of MIN, MAX, last, average and standard deviation per measuring interval
- User-set MIN and MAX alarms with indication on 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
- User adjustment for fine tuning of the calibration if material differs from the used calibration material
- NIST-Traceable Calibration Certification in optionally available
- 1000g and 2000g models are fitted with 7.4mm diameter v-grooved rollers fabricated from hardcoat anodized aluminum
