Specify motion ratio, peak cable speed and ECU input. Review MoTeC, AiM, Haltech or NI interface requirements for the exact acquisition hardware.
Small spaces. Measurable deflection.
Review fixture envelope, cable tension and measurement range for wing structures, crash-test development, robotics and university laboratories.
From hydraulic travel to a digital readout
Select voltage divider, conditioned voltage or current output. Pair a matched meter when the operator needs an inch/mm reading.
THREE WIRES. ONE POSITION SIGNAL.
Passive voltage-divider wiring reference
A passive string potentiometer uses three electrical connections. The wiper voltage follows string travel as a proportion of the excitation voltage.
Ideal relation: Vout ≈ Vexc × x / L. At 50% travel and 5V excitation, an ideal zero-offset output is 2.5V.
Illustrative colors only. Confirm the exact model pinout, maximum excitation and power rating. Do not apply 24V unless the specified unit permits it. Conditioned voltage and two-wire current-loop models need their own wiring diagram.
