The DTFB Limited Access Digital Tension meter accurately measure the running line tensions of yarns, fibers, wires, cables and similar process materials. Long, flat fingers and miniature 7.4 mm diameter V-grooved rollers permit measurement in areas with limited space or tightly grouped filaments.
DTFX Additional Features
- Built-in datalogging with RS232 and 0-1 VDC Analog output
- Memory capacity of 100 values plus min, max, peak, avg and standard deviation
- Optional TensionView software available for batch download or continuous real-time trending
- Roller shifting mechanism ensures easy acquisition of the running material
- Small measuring head, allows access where space is limited or where filaments run close together
- Turned-up outer finger edges guide the running filament into the roller grooves
- Calibration to customer supplied material is available
- Minature 7.4 mm diameter V-Grooved rollers for material speeds up to 900 meters/min
