Considerations for Selecting LVDT Sensors
When choosing LVDT sensors for your application, several critical factors should be considered to ensure optimal performance and compatibility:
- Measurement range: Determine the required range of linear displacement for your specific application. Ensure the LVDT sensor can accurately measure the full extent of movement you need, as this will directly impact the precision of your readings.
- Sensitivity and resolution: Evaluate the sensitivity and resolution specifications of the sensor. Higher sensitivity and resolution are essential for applications that require precise measurements, so select an LVDT sensor that meets your specific needs.
- Output type: LVDT sensors can provide different output signals, such as analog voltage, current, or digital signals. Make sure the output type is compatible with your control systems to facilitate seamless integration and effective data acquisition.
- Environmental conditions: Consider the operating environment where the sensor will be used. Factors such as temperature extremes, humidity, vibration, and exposure to contaminants can affect performance. Choose a sensor designed to withstand these specific environmental challenges.
- Mounting and size: Assess the physical dimensions and mounting requirements of the LVDT sensor. Ensure that the sensor can fit into your installation space and is easy to mount within your system setup.
- Response time: Depending on your application, the response time of the sensor may be critical. For dynamic applications that require real-time feedback, select LVDT sensors with faster response times to ensure timely data collection.
By carefully considering these factors, you can select the most suitable LVDT sensor for your needs, ensuring reliable operation and accurate measurements in your application.

Frequently asked questions about LVDT sensors
Answers to the most important technical Questions
For which applications are LVDT displacement transducers and LVDT probes particularly suitable?
LVDT displacement transducers and LVDT probes are particularly suitable for precise linear position and displacement measurements where high repeatability, low hysteresis and long service life are important.
Typical applications include automation, test benches, industrial machinery, aerospace and applications involving high measurement cycle rates.
Thanks to their contactless measurement technology, LVDT sensors operate with minimal wear, making them ideal for continuous operation in demanding environments.
AC LVDTs are particularly suitable for applications with limited installation space or high temperatures and humidity, while DC LVDTs with integrated signal conditioning are well suited for direct integration into control and data acquisition systems.
We will be happy to help you select the right LVDT displacement transducer or LVDT probe for your application, installation requirements and measurement needs.
What accuracy can I achieve with an LVDT displacement transducer?
LVDT displacement transducers can achieve very high accuracy, depending on the product series. For many industrial Althen LVDT displacement transducers, non-linearity is typically ±0.25% of the measuring range, as with the PR series.
Other versions, such as the E series or PCA-375 displacement probes, have a non-linearity of around ±0.5%, while individual variants achieve up to ±0.1% FR.
In addition to linearity, repeatability is an important factor. LVDT sensors operate without mechanical contact, have very low hysteresis and offer virtually infinite resolution. The PCA-375 displacement probe, for example, achieves a repeatability of 1.5 µm.
The achievable measurement accuracy depends on the measuring range, signal conditioning, mounting, temperature, vibration and environmental conditions.
We will be happy to help you select the right LVDT displacement transducer for your accuracy requirements.
What measuring ranges are available for LVDT displacement transducers and LVDT probes?
Althen LVDT displacement transducers and LVDT probes are available for a wide range of linear displacement measurements, from very small movements to larger measuring ranges, depending on the product series.
Typical measuring ranges extend from a few millimeters to approximately 250 mm. For example, the PR series offers measuring ranges from ±1.25 mm to ±250 mm, while the HCD series covers 1.27 to 254 mm.
Compact displacement probes are available for smaller strokes, such as the PCA-375 series, with measuring ranges from ±2.54 mm to ±25.4 mm. Other versions cover ranges such as ±2.54 mm to ±50.8 mm or 0 to 152.4 mm.
The appropriate measuring range depends on the application, available installation space, required resolution, output signal and environmental conditions.
