Draw Wire Position Sensors | String Pots | Cable Extension Transducers

This section illustrates our range of string pots, also known as cable extension transducers or draw wire position sensors, which offer a compact and highly accurate way of measuring displacement and position. Ranges available start from as low as 0-50mm right up to 0-50m.

Cable extension transducers are inherently accurate devices as they utilise either rotary potentiometers or rotary encoders as their sensing element. Accuracy ranges from ±0.01 of full scale on high performance encoder based units to ±0.25% on low cost budget models.

Our string pots are available with various electrical outputs including R1K potentiometer, 0-10Vdc, 4-20mA and digital SSI serial.

Environmental protection levels range from general industrial right up to IP68, making string pots suitable for even the harshest and most demanding applications.

All string pots can be supplied with digital displays / indicators, signal digitisers, telemetry systems, data loggers and acquisition equipment.
