Overview
The DTMB/DTMX Electronic Tensile Force Meter is a precision-engineered, contact-based force measurement system designed for real-time tension monitoring of moving linear materials—including wires, cables, fibers, foils, films, and textile yarns—in industrial production and laboratory environments. Operating on the principle of calibrated load-cell deflection under controlled mechanical constraint, the instrument measures tensile force via a dual-pulley (capstan) configuration where the material passes over precision-ground guide rollers mounted on a high-stiffness lever arm. The resulting bending moment is converted into an electrical signal by a temperature-compensated strain-gauge load cell, enabling traceable, repeatable force quantification in accordance with ISO 376 and ASTM E4 standards for force transducer calibration.
Key Features
- Modular guide frame and hardened steel guide rollers ensure low-friction, non-damaging material entry—critical for delicate or coated substrates.
- Integrated mounting holes conform to DIN 3320 and ISO 2768-mK dimensional tolerances, enabling direct in-line installation on extrusion lines, drawing towers, winding stations, and coating systems.
- Zero-point adjustment functionality accessible via front-panel interface or remote command, supporting dynamic recalibration during operation without mechanical disassembly.
- Onboard material diameter compensation algorithm corrects for geometric cross-sectional variation—essential when measuring tension across spools with changing wire gauge or fiber bundle density.
- Rugged aluminum alloy housing with IP54-rated enclosure provides resistance to dust ingress and incidental moisture, suitable for factory-floor deployment near cooling baths, lubricant mist zones, or ambient-controlled cleanrooms.
- Standard analog output (0–10 V / 4–20 mA) and optional RS-485 Modbus RTU interface enable seamless integration with PLCs, SCADA systems, and MES platforms for closed-loop process control and SPC charting.
Sample Compatibility & Compliance
The DTMB/DTMX supports continuous measurement of materials with diameters ranging from 0.05 mm to 6.0 mm and nominal tensile forces between 0.1 N and 500 N (model-dependent). It is validated for use with metallic conductors (copper, stainless steel, aluminum), polymer monofilaments (PA6, PET, PP), carbon and aramid fibers, and laminated foils. All internal electronics comply with EN 61326-1 (EMC for industrial environments) and EN 61000-6-2/6-4. Mechanical components meet RoHS 2011/65/EU and REACH SVHC criteria. Calibration certificates are issued per ISO/IEC 17025:2017 by DAkkS-accredited laboratories upon request.
Software & Data Management
The instrument operates autonomously but may be paired with optional TensionLink™ PC software (v3.2+) for data logging, statistical analysis (Cp/Cpk, trend charts), and report generation compliant with FDA 21 CFR Part 11 requirements—including electronic signatures, audit trails, and user-access-level controls. Raw force values are timestamped at 100 Hz sampling rate and stored in CSV or SQLite format. Batch export supports GLP/GMP documentation workflows, with metadata fields for operator ID, material lot number, line speed, and environmental conditions (temperature/humidity logged via optional external sensors).
Applications
- Real-time tension control during copper wire drawing to prevent necking, breakage, or surface scoring.
- Quality assurance in optical fiber preform feeding and fiber coating processes.
- Validation of tension stability in lithium-ion battery electrode slitting and foil winding operations.
- Process qualification for medical-grade suture thread manufacturing per ISO 10993-1 biocompatibility protocols.
- Research-scale characterization of creep behavior in high-performance composite tows under constant load profiles.
- Verification of tension uniformity across multi-lane flat cable extrusion dies prior to annealing.
FAQ
Is the DTMB/DTMX suitable for high-speed applications?
Yes—mechanical response time is ≤15 ms, supporting stable measurement at line speeds up to 1,200 m/min when used with appropriate roller surface finish and alignment.
Can the device be recalibrated on-site without returning to the manufacturer?
Yes—zero and span adjustments can be performed using NIST-traceable deadweight kits (optional accessory); full calibration verification requires accredited lab service.
Does it support automatic diameter input from upstream gauging systems?
Yes—via analog voltage input (0–10 V) or Modbus register mapping, enabling real-time diameter feed-forward compensation.
What is the recommended maintenance interval?
Visual inspection and roller cleaning every 500 operating hours; load cell verification annually or after impact events.
Is explosion-proof certification available?
ATEX Zone 2 and IECEx certification is offered as a custom variant (DTMX-EX series) with intrinsically safe barrier integration.
