Find the right tension measurement, telemetry, signal transmission, or strander monitoring path in less than 60 seconds.
Choose whether you need fixed pulley tension measurement, strand tension monitoring, wireless signal transmission, brake control, or cradle monitoring.
Identify the machine type, such as a payoff, take-up, wire drawing line, cage strander, tubular strander, buncher, twister, or cabler.
Enter the approximate tension range, number of strands or rotating signals, and how the data should be displayed, transmitted, or controlled.
Wire and cable tension systems are highly application-specific. Sensor selection depends on tension range, pulley geometry, wrap angle, machine layout, rotating sections, signal requirements, and whether the goal is simple measurement, individual strand monitoring, wireless telemetry, closed-loop brake control, or cradle-level fault detection.

Gauge Advisor Tool
Find the right solution path for wire tension measurement, strander telemetry, wireless signal transmission, brake control, or cradle monitoring.
Start by identifying whether the tension point is stationary or part of a rotating wire machine.
Choose the main goal. Available options will narrow based on the project type selected above.
Choose the closest machine or process type.
Choose the details that apply to the selected goal or combination of goals.
Enter the additional signals that must cross from the rotating machine section to the stationary controls. Do not count cradleGUARD switch inputs here. Select a sensor goal separately when a new force sensor must also be sized.
RTM X42.CC is required for RTM X42.BC operation. Choose whether the control data must also be integrated with the machine PLC.
Choose the cradle count, switch types, and desired fault output. cradleGUARD monitors discrete safety/fault signals; it does not measure tension.
Signals to monitor
Choose the approximate sensor force or measurement range you already know. If you only know material tension, use the optional calculator below to estimate the resultant force at the sensing pulley.
Calculate from line tension and wrap angle
The cards below show how the recommended sensor, electronics, telemetry, software, control, and monitoring components fit together.
Final details should be reviewed with Gauge Advisor and confirmed with FMS using the actual machine layout, tension range, pulley geometry, rotating architecture, signal requirements, and control needs.
Many wire and cable lines need both tension control and dimensional measurement. Use the Wire & Cable Measurement Selector to narrow the starting path for OD, ovality, wall thickness, concentricity, surface defects, FFT/SRL analysis, and multi-strand measurement.
For fixed-pulley applications, the tool uses the selected known sensor-force range directly, or a completed line-tension and wrap-angle calculation, to narrow the force-sensor family.
For stranders, bunchers, twisters, and cablers, the tool considers whether tension data or machine signals need to move from rotating equipment to the stationary controls.
A rotating project only shows the requirement groups that affect the selected goal: strand data, rotating signal counts, brake integration, or cradle monitoring. The output cards show the resulting system path.
Final review should confirm sensor force, pulley weight, wrap angle, entry and exit angles, speed, machine layout, number of bays, and PLC requirements.
Wire & Cable Tension Systems Overview
The selector above recommends the best starting approach. Below is a visual reference of the primary FMS force sensors, telemetry systems, signal transmission options, and cradle monitoring technologies used in wire and cable applications.
Compact / Lower Tension
Compact force sensor for pulley-based wire and cable tension measurement. A good starting point for lower-force stationary measurement points such as payoff, take-up, rewinding, extrusion, drawing, and other non-rotating machine sections.
Flexible Pulley Mounting
Compact pulley force sensor with flexible installation options. Useful when the application needs standard pulley compatibility, compact mounting, higher force capacity than small low-tension sensors, or special installation options.
Medium Pulley Tension
Medium-size pulley force sensor for wire and cable tension measurement where a more robust stationary measurement point is required. Often reviewed for medium force ranges and general machine-frame tension sensing.
Heavy-Duty Tension
Heavy-duty force sensor for higher-force wire and cable tension measurement. Used when the application requires a larger nominal force range, rugged pulley-based sensing, or a more robust tension measurement setup.
Harsh Environment
Force measuring journal for demanding tension measurement environments. A strong fit when moisture, temperature, chemical exposure, or rugged installation conditions are important factors in the sensor selection.
Signal Processing
Measuring amplifiers process the force sensor signal and provide the usable output for display, calibration, PLC integration, or control. Amplifier selection depends on output type, channel count, mounting style, and communication requirements.
Strander Telemetry, Control & Safety Options
For stranders, bunchers, twisters, cablers, and other rotating wire machinery, the system may need to measure individual strand tension, transmit signals wirelessly, connect to a PLC, control brakes, or monitor cradle safety signals.
Low-Tension Stranding
Compact force sensor for low-tension rotating stranding applications. Commonly reviewed for smaller, higher-revolution planetary or tubular stranders, bunchers, and twisters where individual strand tension must be measured.
Medium-Tension Stranding
Force sensor for medium-tension planetary stranders, tubular stranders, bunchers, and twisters. Often used with RTM telemetry when sensor signals need to be transmitted from the rotating machine section.
Simple Telemetry / Analog PLC Output
Wireless telemetry system for monitoring wire tension on cage and tubular stranders. A practical fit when the application needs basic rotating tension monitoring with analog outputs to an existing PLC.
Modular Strander Monitoring
Modular telemetry architecture for individual strand tension monitoring on cage and tubular stranders. Used when multiple strands, cradles, bays, or PLC integration requirements make the system more than a simple sensor installation.
Wireless Signal Transmission
Wireless signal transmission system for rotating wire machinery. Used when encoder, digital, analog, force sensor, or other signals need to move from a rotating section to stationary machine controls without relying on slip rings.
Cradle Safety / Fault Monitoring
Wireless cradle monitoring system for wire break detection, pintle locks, tilt switches, and related safety signals. Best viewed as a safety and fault-monitoring option, not a tension measurement sensor.
Control, Reporting & PLC Integration
After the sensing or telemetry path is selected, the next decision is how the tension data should be viewed, documented, connected to controls, or used for automatic brake adjustment.
PLC / Fieldbus Integration
Digital amplifier options for connecting force sensor data to machine controls using analog outputs or industrial network paths such as EtherNet/IP, PROFINET, EtherCAT, and related PLC integration methods.
Visualization / Recipes / Reports
Software and control center layer for RTM X42 systems. Used when operators need visualization, system configuration, recipe management, quality reporting, or the interface required for brake control.
Closed-Loop Brake Control
Brake control extension for automatic strand tension control on stranding machines. Used when individual strand tension values should drive automatic brake adjustment instead of relying only on manual operator changes.
Selection note: For fixed pulley tension measurement, final sensor sizing depends on actual tension, pulley weight, wrap angle, entry and exit angles, material speed, and installation geometry. For rotating stranders, final system layout also depends on the number of payoffs, bays or lay plates, cradles per bay, monitored strands, controlled strands, available power, and PLC or reporting requirements.
Next Step After the Selector
The selector gives you a strong starting point. Final system selection should still consider the tension range, pulley geometry, machine layout, rotating sections, signal needs, PLC integration, and whether the application requires monitoring, control, or safety diagnostics.
Why This Matters
In wire and cable production, the right tension system can improve process visibility, reduce strand imbalance, support repeatable setups, and help operators catch problems before they become scrap, downtime, or quality issues.
Hidden strand imbalance: Total line tension can look acceptable while individual strands are running too tight or too loose.
Wrong sensor sizing: Force sensor selection depends on more than material tension. Pulley weight, wrap angle, entry angle, exit angle, and machine geometry all affect the force seen by the sensor.
System architecture matters: A rotating strander may need force sensors, wireless telemetry, PLC output, reporting software, brake control, or cradle safety monitoring.
Fixed pulley tension
Use force sensors and measuring amplifiers when tension needs to be measured at a stationary pulley, payoff, take-up, rewinder, extrusion line, or drawing line.
Individual strand monitoring
Use rotating force sensors and telemetry when individual wire or strand tension needs to be monitored on a strander, buncher, twister, or cabler.
Wireless signal transmission
Use wireless telemetry when encoder, analog, digital, force sensor, or safety signals need to move from rotating equipment to stationary machine controls.
Brake control and safety
Use brake control when strand tension should be adjusted automatically, and cradle monitoring when wire breaks, tilt switches, pintle locks, or safety signals need faster fault diagnosis.
System Layer
After choosing the sensor or telemetry path, the next decision is how the signal should be displayed, transmitted, recorded, or used for control.
Basic Signal Output
Measuring Amplifier
Used with force sensors to process the sensor signal for display, calibration, analog output, or PLC connection.
Strander Monitoring
RTM IO or RTM X42
Used when strand tension or rotating machine data must be transmitted wirelessly from a strander, cabler, buncher, or twister.
Control / Reporting
Control Center or Brake Control
Used when operators need recipes, quality reports, visualization, or automatic brake adjustment for closed-loop strand tension control.
Common Questions
Can one total tension reading show individual strand balance?
Not reliably. A total tension value can look correct even when individual strands are uneven. Individual strand tension monitoring is used when balance across strands matters.
Why does pulley geometry matter?
The force sensor sees the resultant force created by material tension, wrap angle, pulley weight, and line geometry. That is why final sizing should review the actual machine layout.
When is wireless telemetry needed?
Wireless telemetry is used when signals need to move from a rotating machine section to stationary controls without relying on slip rings or additional rotating wiring.
