New to FMS? Start with the system job. The force sensor measures the load at the pulley, an amplifier or telemetry connection makes the signal usable, and the display, PLC, reporting, or brake-control layer determines how production uses it.
Pulley force sensors and signal processing
These families cover compact, flexible, heavy-duty, and harsh-environment tension measurement points. Final nominal force still depends on the real geometry.

RMGZ100 force sensor
Compact pulley force sensor for lower-tension wire and cable applications. It can be used on suitable fixed or rotating measurement points.
Review: pulley, mounting, speed, wrap geometry, and nominal force.

CR-Series force sensor
Compact sensor with flexible mounting around a standard pulley supplied for the application. Useful when machine space or pulley selection drives the layout.
Review: pulley design, shaft fit, environment, and any vacuum requirement.

RMGZ400 force sensor
Medium-range pulley sensor for suitable stationary or rotating machinery. It is often considered when a compact low-force family is not enough.
Review: mechanical envelope, options, speed, and exact nominal rating.

RMGZ800 force sensor
Heavy-duty family for higher loads and rugged pulley-based measurement. Depending on the configuration, it can support fixed or rotating applications.
Review: actual resultant force, load direction, environment, and mounting.

JG force measuring journal
Hermetically sealed IP68 journal for demanding wet, humid, or aggressive environments. The selector covers nominal force ratings from 125 to 1500 N.
Review: media exposure, temperature, pulley and bearing arrangement, and cable routing.

FMS measuring amplifiers
The amplifier conditions the force-sensor signal for calibration, display, analog output, a PLC, or control. Models vary by mounting, channel count, interface, and enclosure.
Review: operator display, output, fieldbus, supply, housing, and panel location.
Rotating-machine sensing, telemetry, and safety
Stranders, bunchers, twisters, and cablers need more than a stationary force sensor when readings or machine signals must cross the rotating boundary.

RMGZ200 rotating sensor
Low-tension force sensor for compatible planetary and tubular stranders, bunchers, and twisters. It measures an individual rotating strand rather than total machine tension.
Review: product range, 30:1 measuring span, RPM, mounting, and telemetry.

RMGZ300 rotating sensor
Medium-tension rotating sensor with compensation for centrifugal and Coriolis effects. It is commonly paired with an RTM telemetry system.
Review: machine type, RPM, strand range, mounting, and signal path.

RTM X42 telemetry
Modular wireless system for carrying many individual strand-tension channels off a rotating machine. It supports PLC data and optional visualization or brake control.
Review: bays, positions, rotating power, RPM, radio path, PLC, and reporting.

RTM MP Plus
Compact wireless path for 2 encoder, 8 digital, 1 analog, and 2 force-sensor inputs. It can replace signal paths that would otherwise depend on slip rings.
Function: it is not a substitute for a full multi-channel X42 tension system.

FMS cradleGUARD
Wireless monitoring for wire breaks, pintle locks, tilt switches, and other discrete cradle signals. It helps identify the affected cradle quickly.
Function: cradleGUARD monitors safety and status signals; it does not measure tension.
PLC integration, visualization, and control
After the sensor and telemetry are chosen, decide whether the data is simply displayed, sent to the controls platform, documented, or used in a closed-loop brake system.

Networked measuring amplifiers
Model-dependent amplifier families provide analog or industrial network connections such as EtherNet/IP, PROFINET, and EtherCAT for compatible control systems.
Review: protocol, channel count, PLC data map, mounting, and enclosure.

RTM X42.CC Control Center
The Control Center adds operator visualization, configuration, recipes, trends, and quality reporting to an RTM X42 system. It is also required for X42 brake control.
Review: station count, operator tasks, saved data, networking, and controls interface.

RTM X42.BC Brake Control
Uses measured strand tension to adjust compatible payoff brakes automatically. The goal is more consistent strand tension with less manual brake adjustment.
Requires: X42, Control Center, compatible brake mechanics, and a full safety and controls review.
Four parts of the system
Follow the signal from the wire to the decision
Specify the sensor, signal transmission, display and control functions separately so each part of the system does the job you need.
Measures the resultant load at the pulley or an individual rotating strand.
Converts the signal locally or carries it across the rotating machine boundary.
Gives operators, controls, and quality systems the information they need.
Supports compatible automatic adjustment or faster fault response.
What helps turn a selector result into a quotation
A short description is enough to start. A machine photo, pulley sketch, or controls note can remove a surprising amount of uncertainty.
- Machine type, number of bays, payoffs, cradles, or monitored positions
- Normal and maximum tension for one product, plus the force unit
- Pulley weight, wrap angle, entry and exit geometry, diameter, and RPM if known
- Required display, analog output, fieldbus, reporting, or automatic control
- Environment, mounting space, existing sensor model, and available rotating power
Quick answers
Before you submit the tension profile
Do I need exact tension and pulley geometry to use the selector?
Can one total-tension reading show whether every strand is balanced?
Is the selector result a final FMS part number?

Is the tension point fixed, or does it rotate with the machine?
This first choice determines whether the sensor can be wired directly or whether the measurement and other signals must travel off a rotating section.
A fixed sensor can usually connect directly to a nearby electronics unit. A rotating machine may also need wireless signal transmission, individual-strand monitoring, automatic brake adjustment, or wire-break and cradle-status monitoring.
What are you trying to measure, transmit, or control?
Choose the main job the system must perform. Select more than one need only when the project truly combines separate functions.
Which functions are part of the same rotating-machine project?
Select each separate need. Automatic brake adjustment belongs with individual-strand monitoring rather than with general signal transmission.
Individual-strand monitoring measures tension on each strand. General signal transmission moves existing machine signals across a rotating interface. Cradle monitoring watches on/off fault conditions. A one-sensor replacement may not require any broader system change.
Answer only the questions that apply to your project
The follow-up fields change automatically based on the job you selected, so a fixed tension point is not mixed with rotating signal or cradle-monitoring questions.
Machine or process
The available choices change with the active stationary or rotating path.
Fixed-point display and controls
The sensor needs a small electronics unit, often called a measuring amplifier, to power the sensor, show the reading, and send the value to the machine controls. This path assumes one independent tension point.
The app is useful for local viewing, setup, and basic recording. Longer-term trends, alarms, histories, and reports usually live in the PLC, HMI, SCADA, historian, or plant data system.
Individual-strand tension monitoring
Define the machine layout, normal strand-tension range, and the level of monitoring or control required. The selector keeps these questions practical and leaves final sensor-force geometry to the official calculator.
Machine layout
Count the rotating bays or sections separately. Enter the monitored positions in each bay, not the total across the whole machine.
Normal strand-tension range
Enter the lowest and highest normal running tension for one monitored position. These values screen the usable measuring span; they do not replace the final force-vector calculation. If the range is not available yet, leave both values blank and choose Not sure in the last dropdown.
Power, speed, display and controls
Use the closest preset. Exact channel counts, line speed, cable lengths, and mechanical drawings are still confirmed during application review.
Automatic closed-loop control needs the operator and control software even when a separate software option was not selected above.
Exact positions, extension modules, core-channel treatment, line speed, centerline radius, sensing-pulley geometry, cable lengths, and mounting drawings are confirmed after the preliminary architecture is identified.
Signals that must cross the rotating interface
Enter the existing signal types and quantities that must move from the rotating machine section to the stationary controls. This is separate from monitoring every strand.
The compact path supports up to 2 encoder, 8 digital, 1 analog, and 2 force-sensor inputs. The expandable path can double those quantities. Higher counts require application review.
Cradle and fault-monitoring requirements
Define the number of monitored cradles, the on/off conditions to watch, and where the fault information should appear on the stationary side of the machine.
Rotating sensor replacement or addition
Existing model information improves compatibility review but does not replace confirmation of nominal force, connector, mounting, pulley, and machine speed.
What is the best force information you have?
An official calculator result or a verified sensor nameplate gives the strongest starting point. A known load or a simple line-tension estimate can still narrow the options, but it will remain preliminary.
The minimum and maximum strand tension entered in the previous step check the operating span. This selector does not use a simple wrap-angle estimate to choose a rotating sensor family because pulley weight, force direction, centerline radius, and sensor orientation can materially change the result.
Enter the nominal force
Use the value from the official calculator or the existing sensor nameplate.
Enter the known maximum sensor load
This can screen a likely sensor family, but it is not treated as a final nominal-force rating.
Simple tension-generated resultant estimate
The calculation uses 2 × line tension × sin(wrap angle ÷ 2). It does not include pulley weight, the sensor’s measuring direction, how the sensor is rotated in the mount, or the complete entry and exit geometry.
A cradle-monitoring-only project or a project that only transmits existing rotating signals can continue without force sizing. The machine environment and signal setup still require review.
Installation environment and final details
Choose the actual environment around the sensor. Rotating-machine and slip-ring questions are handled separately so they are not mixed into the fixed-point sensor selection.
Review the application before generating the recommendation
The result will show the likely equipment setup, explain why it fits, and clearly separate preliminary screens from items that still need engineering review.
A simple line-tension estimate can narrow the likely sensor range, but it cannot create a final nominal-force recommendation. An official calculator result or verified nameplate rating is treated as the strongest basis.
