DTMX For applications requiring additional process data
9 ranges, 0.1 - 200.0 cN to 5 - 50 daN
The new CHECK-LINE DTMX Digital Tension Meters accurately measure the running line tensions of yarns, fibers, wires, cables, optic fibers and similar process materials.
It's unique design combines the latest microprocessor technology with the reliability, simplicity and ruggedness found in CHECK-LINE mechanical tension meters.
The DTMX provides the critical process information required to meet today's strict quality reporting systems mandated under ISO 9000 guidelines.
2 Memory modes for 100 data values and statistics:
- Continuous storage
- On-demand storage
Analog and serial interfaces
Calibration to customer supplied material is available (up to four different material calibrations)
Precision V-grooved rollers for line speeds up to 5,000 m/min
Memory for up to 100 tension values plus MIN, MAX, PEAK values
- automatic calculation of average and standard deviation
-all these data values can be recalled in the display or downloaded to a printer or Personal Computer.
Material selector switch for textile and wire applications (Tex and Wire) assures highest accuracy
Selectable update rates
(0.5, 1, 2, or 4 seconds) to
provide steady readings
when tensions fluctuate
Built-in mounting holes
permit fixed installation
for online use
Can be connected to a PC or printer for data output
DIP switch for adjustment by operator, e.g. display update rate
Certificate of Compliance with the order 2.1 according DIN EN 10204 is included
Optionally available: Inspection Certificate 3.1 according DIN EN 10204 with calibration report
DTMX Advanced Features
The DTMX built-in datalogger stores up to 100 tension values and automatically calculates maximum, minimum, peak, average and standard deviation values. The data values and summary statistics can be recalled to the display for viewing or downloaded to a printer or Personal Computer.
The datalogger can be set to store in two different modes. In the On-Demand Mode, a tension value is stored, each time the STORE key is pressed. In the Continuous Mode, the STORE key is pressedto start continuous datalogging. Each displayed value will be stored until the memory is filled or until the STORE key is pressed again to stop the datalogging. The stored data is retained in memory for the life of the batteries.
Other measuring head widths available on request.
Other units of measure are available, such as g or kg and oz or lb.
* Depending on model, either width of filament guide or outer distance between outside guide rollers
***MTC = Material Thickness Compensator
Special Purpose Models
32 mm dia. rollers for fragile materials sensitive to bending over a small radius.
Rollers are available in plastic or aluminum.
Cylindrical rollers are available in 10,
15, 20 and 30 mm widths with single or dual flanges.
