Precision Linear Motion Potentiometers

Precision Linear Motion Potentiometers

Linear displacement sensors for distance measurement

The most cost-effective method for measuring mechanical linear motion is the proven linear potentiometer. Measuring lengths of 8mm up to 1500mm. Wide variety of mounting styles and mechanical interfaces; push rod shafts with or without spring loading, rod end bearings, sliding cursor (shaftless), threaded shaft ends, probe tips, through shaft (rear shaft). High resolution (essentially infinite) and high measuring dynamics (shock, vibration, speed, etc.) to meet the requirements for industrial use. Absolute position sensing, signals and measured values ​​are retained (true power on) even if the supply voltage is interrupted.

Our linear motion potentiometers have applications across all industrial sectors; process control automation, heavy equipment, hydraulic machinery, manufacturing automation, valve controllers, medical equipment, aerospace, material handling equipment, etc.

Customization

Should your application require special adaptations to one of our existing products or a completely new design, we can partner with you to deliver a sensor to your specifications. It is not unusual for fractional measuring lengths, improved precision, temperature tolerance or special wiring requirements to be met for serial or occasional production.
