Displacement sensors

Purpose and Operating Principle

Potentiometric Linear Position Sensors are designed for the absolute measurement of an object's linear motion (displacement).

Their operating principle relies on a linearized conductive plastic resistance (resistor) that changes its value as the actuator rod moves. This change in electrical resistance is directly proportional to the change in position.

Due to this absolute nature, the sensors do not lose their position measurement when power is disconnected, which is crucial for automation systems requiring reliable referencing.

Key Advantages and LTM Series Features

• Durability and Longevity: Thanks to the linearized conductive plastic track and special contacts, these sensors are wear-resistant and offer a long service life of up to 100 million cycles.

• High Accuracy: Ensure stable and precise linear motion measurements every time.

• Environmental Resilience (Crucial Clarification): While basic potentiometers may be sensitive to vibration and temperature fluctuations, modern industrial models (like the LTM Series) offer enhanced stability for harsh environments.

• Ease of Integration: The LTM Series is a frequently used model in the industry, noted for its ease of use and installation.

• Output Options: Various analog output signals are available for seamless integration into any control system:

  • Potentiometric Analog Output.

  • Current: 4-20 mA (optional 0-20 mA).

  • Voltage: 0-10 V.
