Linear Potentiometer
Precision Displacement Sensor with Signal Conditioner
High-Accuracy Linear Position Sensor with Integrated Signal Conditioning
The Linear Potentiometer is a precision displacement sensor designed to convert linear mechanical movement into a proportional electrical signal. It offers high accuracy, excellent repeatability, and reliable performance for industrial, aerospace, and automation applications.
Operating Principle
- Voltage divider principle: Linear movement of the actuator causes the wiper to traverse along a uniform resistive track
- Proportional output: Output voltage is proportional to the displacement relative to the total stroke length
- Integrated signal conditioner: Provides 4–20 mA, 0–20 mA, or 0–10 V outputs
Key Features
- Measurement stroke: 30 to 1250 mm
- High linearity: ± 0.05%
- Excellent repeatability: < 0.01 mm
- Infinite resolution for precise position feedback
- Multiple output options: 4–20 mA, 0–20 mA, 0–10 V
- Long mechanical life: 100 million cycles
- High durability: Anodized aluminium housing, stainless steel rod
- IP65 protection for harsh environments
- Wide operating temperature: -20°C to +80°C
