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. -
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). -
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. -
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. -
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 2,000 m/min. Optional High-Speed Rollers (U) are offered for 5,000 m/min. Hardened steel, ceramic and plastic rollers are also available -
Rugged Aluminum Housing For Long-Term Durability
Die-cast aluminum housing and surface-mount electronics insure trouble free operation in the toughest environments. - NIST-Traceable Calibration Certification optionally available
-
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.
DIP switch
for adjustment by operator e. g. display update rate
• Saving MIN, MAX and PEAK values during a user-selected period. These values can be recalled at the display.
Material thickness compensator: For better accuracy the material to be measured or a similar material with the same diameter should be inserted
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.

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.
