Digital Tension
Meter - DTM
DTMB / DTMX
(Data-logging Model)
9 ranges, 0.1 - 200.0 g to 5 - 50 Kg
The new CHECK-LINE® DTMB and DTMX
Digital Tension Meters accurately measure the running line tensions of
yarns, fibers, wires, cables, optic fibers and similar process
materials.
Their unique design combines the latest
microprocessor technology with the reliability, simplicity and
ruggedness found in CHECK-LINE mechanical tension meters.
The DTMB and DTMX provide the critical
process information required to meet today's strict quality reporting
systems mandated under ISO 9000 guidelines.
The DTMB models are for general purpose applications,
while the DTMX models are for those requiring advanced
capabilities such as:
- A built-in memory for 100 data values
and statistics
- Download capability of stored data and
statistics to printers, computers or chart recorders
- Hand-held or continuous on-line use
|
Applications:
|
- Yarns
- Fibers
- Wire
- Cables
- Optic Fibers
- Tire Cord
|
- Webs & Warps
- Tapes & Bands
- Tows
- Ribbons
- and more
|

Precision
Strain Gauge Sensing for Highest Accuracy
A precision strain-gauge sensing system accurately measures the
force on the middle sensing roller. This is converted into a highly
accurate tension measurement using proprietary calibration formulas
which correct for material diameters, rigidities, gravity and other
critical parameters.
High-Speed Measurement Captures
Max, Min & Peak Tension Values
Tensions are sampled 62 times per second and averaged over a user
selected interval of 0.5, 1, 2 or 4 seconds. The maximum, minimum
and peak values are stored for recall to the display.
Rugged Aluminum Housing For Long-Term Durability
Die-cast aluminum housing and surface-mount electronics insure
trouble free operation in the toughest environments.
Thickness Compensator Automatically Adjusts Calibration
The microprocessor automatically fine-tunes the calibration to
correct for different material diameters permitting a single DTMB or
DTMX to be used on a wide range of process materials without sacrificing
precision or accuracy.
Field Adjustment for Fine Tuning of the Calibration
Increase or decrease the displayed readings in 1.5% increments
or select Special Calibration (SP). |
Mounting
Holes Permit On-Line Continuous Use
Threaded mounting holes permit convenient, fixed installation
for continuous on-line measurement. The DTMX model provides analog and
serial outputs for data collection and tension trend analysis.
Precision V-Grooved Rollers for
Line Speeds Up to 5,000 m/min
Ball-bearing mounted, V-grooved rollers are hard coated aluminum for
speeds up to 2,00 m/min. Optional High-Speed Rollers (U) are offered for
5,000 m/min. Hardened steel, ceramic and plastic rollers are also
available.
| Additional
Features --- DTMX only |
User-Selected
Calibration Formulas For Highest Accuracy
Select "Textile", "Wire", or
"Special" calibration (SP1 or SP2). Special
calibration is performed by the factory or by the end user with
a specific sample of the process material.
Store Tension Data & Output to Printers &
Computers
Store tension data on-demand or continuously
with the DTMX built-in datalogger. Stored data and statistics
can be output to printers, computers or chart recorders.
|
|
| The DTMX complete
kit includes the tension meter, four (4) AA batteries,
needle nose pliers, operating instruction manual and output
connector (DTMX only) -- all supplied in a foam fitted
carrying case. |

Notes
1. Application Guidelines for Textiles refer specifically to nylon
monofilament.
2. Application Guidelines for Wire refer to soft annealed copper
wire
3. DTMB models are calibrated with monofilaments only.
If customer
sample varies greatly in diameter or rigidity,
special calibration
with customer sample is recommended.
4. Calibration in ounces/pounds and cN/daN is optionally
available.
*These models require
customer supplied samples for calibration.

Built-in
Datalogger
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. |
Print Stored Data On
Battery-Powered Printer
The data and
statistics stored in the DTMX's datalogger can be downloaded to
the P-DTMX portable, battery-powered printer. Its rechargeable
batteries make it convenient to use anywhere, including the
production floor. The hard-copy printout is ideal for ISO 9000
quality reporting systems.
Connect Chart Recorders For
Tension Trend Analysis
The DTMX provides a continuos 0 - 1 V DC analog output that can be
connected to Chart Recorders for continuous trending analysis.

TensionView
Data Transfer & Analysis Program For The DTMX Tension
Meter
|
 |
TensionView
is an easy-to-use program designed to display, record, graph
and print data transferred from the Check-Line DTMX Tension
Meter. Data can be viewed in real time, as it’s being
recorded or at a later time after batch downloading from the
DTMX’s built in datalogger.
