Linear Motion Sensors & Transducers (LVDT)

Linear Motion Sensors & Transducers (LVDT)

Linear Variable Differential Transducers (LVDT) featuring high-resolution, contactless measuring, and extremely long service life.

LVDTs, also called linear variable displacement transformers, which operate on the principle of the differential transformer. They measure the motion of an object in one direction along a single axis and output an electrical signal in proportion to the distance an object has traveled. The standard electrical output signal is in mV/V, requiring external signal conditioning. Our DC output types feature a built-in signal conditioner providing analog voltage or milli-amp outputs.

Contact P3 America to discuss your requirements for linear LVDT transducers. You can even talk tech with our engineers right over the phone. Call (512) 337-7336.

About Linear Variable Displacement Transducers

Linear Variable Differential Transducers (LVDT) are sensors optimized for applications with small strokes and especially for applications in which oscillating movements with high dynamics or high accelerations have to be recorded. Common applications include process gauging instruments, industrial process control systems, factory automation systems, heavy equipment, manufacturing technology, and engineering. P3 America is a leading provider of LVDT linear distance transducers and LVDT position sensors.

Attributes of LVDT Sensors

  • Sealed sensor (high IP protection) 
  • High precision linearity
  • Able to measure micro displacements
  • Near infinite resolution
  • Durable, consistent accuracy
  • Maintenance and wear-free
  • Suitable for high dynamics
  • Reproducible zero point
  • Absolute signal output
  • Insensitive to many chemicals

Extensive Mechanical Life

Because LVDT sensors operate without contact, they are built to last. They can operate in environments of high vibration and extremely hot or cold temperatures while withstanding water and other contaminants. This means they are dependable when the stakes are high. With P3 America’s competitive pricing and quality manufacturing, you’ll get peace of mind knowing you’ve made a good investment. All linear variable differential transducers are manufactured in accordance with ISO9001 certification standards.

Contact P3 America

FAQs

What types of transducers are available?

Our Linear displacement transducers (linear sensors) are available in five different measurement principles:

What is the measuring principle and the benefits of LVDT sensors?

The LVDT is an absolute analog position sensor that is based on inductive technology, consisting of a primary coil and two secondary coils. These coils convert the linear motion of the shaft movement into electrical signals that can be processed for accurate control and measurement. Being inductive, the sliding wiper used with potentiometers is not required, and thus, is wear-free.

What is the correct name for LVDT?

There are multiple terms for LVDT, but all refer to the same type of device, sensors used to precisely measure linear motion & displacement. All of the following terms are correct:

  • Linear Variable Differential Transducer
  • Linear Variable Displacement Transducer
  • Linear Variable Differential Transformer
  • Linear Variable Displacement Transformer

What is the difference between an LVDT and other potentiometers?

LVDT sensors feature a longer operational lifespan and better resistance to environmental factors like temperature, vibration, and shock. LVDTs are frictionless and do not suffer from mechanical wear like potentiometers, making them more reliable for long-term use.

Can my LVDT sensors be customized?

Yes. We’re happy to customize aspects of your LVDT sensors, such as the measuring range and mechanical interface. Call to talk with one of our applications engineers who will help find or modify our stock to meet your exact specifications. (512) 337-7336.
