Linear Potentiometers: Purpose, Application & Functionality

Linear potentiometers are a type of variable resistance sensor designed to measure the displacement of a slider or wiper in a linear direction. Also known as a slider or pot, linear potentiometers produce a changing rate of resistance, dependent on the position of a slider or wiper. A linear taper potentiometer is usually made up of three pins that adjust to a voltage flow and produce a regulated voltage output relevant to its sliding components. Linear potentiometers can be applied in various industries, including farm equipment, industrial processing, marine, and medical.  
 

LINEAR POSITION SENSOR TYPES

At Curtiss-Wright, we provide a range of linear potentiometers, transducers, and linear position sensors. All have many similarities, including long operational life, highly reliable, and suit the harshest environments.
 

(LVDT) TRANSDUCERS

The technology inside an LVDT transducer differs from linear potentiometers. A nickel-iron core with wire coils decides the voltage output and converts it to an electrical energy source. The central position of the nickel-iron core then controls the movement of the selected object. As a result, LVDTs tend to have a marginally longer life expectancy than linear potentiometers. However, they can be a more costly option due to their contactless nature.

 

LINEAR POTENTIOMETERS

Linear potentiometers are contacting sensors that tend to have a shorter life expectancy than LVDTs. But their lack of electronics means it is often the more effective solution for an application.    
 

BENEFITS OF LINEAR POTENTIOMETERS & LVDT TRANSDUCERS:

  • Able to function in the most hostile environments
  • High accuracy
  • Frictionless operation
  • Long life expectancy
  • Wide operating temperature range

Linear Position Sensors

Linear potentiometers and transducers are also known as linear position sensors. The device detects movement in a linear motion; the sensor then converts the movement into output signals suitable for processing.

Linear Position Sensors Applications

The device is used throughout many industries, including; motorsport, industrial processing, test/lab applications, medical applications, industrial machinery, and many more. 

FAQS

What does a linear position transducer measure?

This type of component measures linear displacement or movement along a single axis in any direction. It does this by converting the motion into an electrical signal proportional to the displacement.

What does a position sensor measure?

A position sensor measures the mechanical position of an object. For example, it may indicate the linear travel's absolute position (location) or relative position (displacement).

How does a linear displacement sensor work?

A linear displacement sensor measures movement or position along a single axis. The sensor is connected to an object, and as the object moves, the technology inside will measure the distance traveled and give an output.
