Special Features Model ETB
top
- Hand-held unit with ball-bearing mounted, V-grooved guide rollers up to 2000 m/min for higher line speed use model ETPB or ETPX
- Tension meter with guide rollers mounted on long shafts to reach into tightest places
- Storage of AVG, MIN, MAX and PEAK tension values which can be recalled in the display
- Adjustable electronic damping for better reading when tension is constantly changing
- LCD display with illuminated background for better reading
- Display of the tension meter can be reversed for right and left hand use to reach all measuring positions easily
Additional Special Features model ETX
- 2 interfaces: 1. serial interface (RS 232) for connecting to a PC
2. analog interface (0 - 2 V) for connecting to a line recorder - Memory of max. 4000 displayed tension values split up to 255 series of measurements and statistics (Last, AVG, MIN and MAX of displayed values, MIN-PEAK and MAX-PEAK are values measured within a measuring frequency of 5 kHz)
- 4 different memory modes can be selected by the operator:
- Mode S: only statistical values per series are displayed
- Mode L: statistics plus 10 displayed values of each series of measurement
- Mode C: statistics plus 4000 displayed values arbitrary splited up to 255 series
- Mode F: as C plus higher sampling rate of 100 Hz = values/s
 | Model ETX can be connected to a PC with the cable ETX-CC. (max. 80 values/s can be transfered, depending on tension range). With the programm SW-TI2 »Tension Inspect 2« readings can be displayed, statistically analyzed and saved. For more information see "accessories" |
