Wiring & Installation Guide

Six practical references for reliable force-sensor wiring, signal integrity and mechanical installation.

Wiring and installation guide sections
01

Wiring & Installation

Universal guidance for strain-gauge load cells, force transducers and load pins.

A reliable measurement starts long before calibration.

Correct wiring protects a millivolt-level signal. Correct installation ensures that 100% of the intended force — and no parasitic force — passes through the sensing element.

S S-Type Tension / compression
1
B Beam Platforms / hoppers
2
C Column High-capacity compression
3
P Load Pin Clevis / sheave / linkage
4

The precedence rule

Serial-number calibration certificate → model datasheet / outline drawing → this general guide → generic practice.

Never assume wire colours

Industry wire colours are not standardised. Verify every conductor against the supplied certificate before applying excitation.

Four non-negotiable safety rules

  1. Never weld through an installed sensor.Remove or electrically bypass it; place the return clamp beside the weld.
  2. Never lift a sensor by its cable.Cable pull-out damages internal seals and strain-gauge wiring.
  3. A sensor is not a safety device.Provide an independent mechanical load path in lifting applications.
  4. Hazardous areas require certified hardware.Use an approved Ex sensor and matched intrinsic-safety barrier.
02

4-Wire vs. 6-Wire

Understand the bridge, the sense leads and why cable resistance changes span.

Wheatstone bridge

Vout = Sensitivity × Vexc × Load / Capacity

Example

2.0 mV/V × 10 V × 50% load = 10 mV output. The signal is tiny — cable and EMI discipline matter.

Ratiometric measurement

Excitation and signal must enter the same instrument. Never power the bridge from one supply and reference the signal to another.

Connection decision

4-Wire

Use only when the factory cable is short, uncut and kept at a similar temperature to the instrument.

+EXC
Excitation +
-EXC
Excitation −
+SIG

6-Wire — Recommended

Adds two high-impedance sense leads. The instrument measures true voltage at the sensor and compensates for cable drop and temperature.

Use 6-wire when

  • Cable run is over ~10 m
  • Factory cable is cut, extended or joined
  • Sensor and instrument see different temperatures
  • Legal-for-trade accuracy is required
  • Multiple sensors feed a distant junction box
03

Clean Signal Wiring

Shield correctly, separate power circuits and verify the bridge before energising.

Shield at one end

Bond the cable shield at the instrument / cabinet end only. Keep it isolated at the sensor end to avoid a ground loop.

The shield is not a return

Never use the drain or shield as −EXC, signal common or any current-carrying conductor. Maintain continuity through junction boxes.

Cable routing

Cross at 90° • Separate conduit • Never coil surplus cable — lay it in a figure-of-eight.

Pre-power checks

Input resistance

Measure +EXC to −EXC

Must match the datasheet tolerance.

Output resistance

Measure +SIG to −SIG

Usually slightly lower than input resistance.

Insulation

Bridge wire to sensor body

Target: > 5000 MΩ at 50 V DC.

Shield

Shield to every bridge wire

Must be open circuit / infinite.
Caution Use a 50 V insulation tester — never 500 V or 1000 V on the strain-gauge bridge.
04

Summing & Outputs

Connect multiple sensors correctly and choose an output suited to the cable run.

Parallel summing

 
5

All sensors: same model • same capacity • same rated output • label both cable ends

Check excitation drive capability

Rtotal = Rbridge / n Four 350 Ω bridges = 87.5 Ω total load

If the instrument cannot drive this resistance, excitation sags and the reading becomes low or unstable.

Choose the right output

mV/V

Highest intrinsic accuracy

Short, protected runs to a dedicated load-cell input.

0–10 V

Simple PLC integration

Short runs; use a high-impedance differential input.

4–20 mA

Long, noisy cable runs

Industrial default; 0 mA provides broken-wire detection.

RS-485

Multi-node digital bus

Daisy-chain only; 120 Ω termination at both physical ends.

05

Five Installation Rules

Most “sensor accuracy” faults are mechanical: binding, side load, poor surfaces or bad fastening.

  1. 01

    One load path

    All measured force must pass through the sensor. Flexible pipes, tight cables and contact points create shunts.

  2. 02

    Axial loading

    Align the force with the calibrated measuring axis. Eliminate side load, bending moment and torsion.

  3. 03

    Flat + stiff

    Use clean, flat, parallel and sufficiently hard mounting surfaces on a structure much stiffer than the sensor.

  4. 04

    Correct bolting

    Use the specified bolt grade and torque. Tighten in a star pattern through progressive stages.

  5. 05

    Overload control

    Fit travel stops, uplift restraint and impact protection. Size for dynamic loads, not static weight alone.

Torque is model-specific — always use the product datasheet, never a generic torque chart.
06

Load Pin Installation

A load pin is directional. Bore condition, shear-plane geometry and angular locking control accuracy.

Double-shear load path

6
  1. 1

    Bores

    Clean, round, deburred and within the drawing tolerance. Re-bush worn or oval holes.

  2. 2

    Direction

    Align the arrow, flat, slot or cable reference with the true radial load direction.

  3. 3

    Anti-rotation

    Engage and bolt the keeper plate / key. Rotation by θ reduces indicated force by cos θ.

  4. 4

    Retention

    Fit the specified circlip, end plate or nut without adding axial preload.

  5. 5

    Cable

    Route away from ropes, sheaves and pinch points. Clamp nearby and leave a service loop.
