Frequently asked questions about Rotary inductive position sensors
Answers to the most important technical Questions
When is an inductive rotary position sensor the right choice?
An inductive rotary position sensor is the right choice when angular or rotational position needs to be measured without contact, with minimal wear and high reliability. This type of inductive position sensor is particularly suitable for applications requiring robust sensing, long service life and stable measurement performance under demanding environmental conditions. Typical applications include mechanical engineering, industrial automation, robotics, vehicle technology, construction machinery, aerospace, and the energy and process industries. Inductive rotary position sensors are particularly useful when dust, moisture, oil, vibration, temperature fluctuations or electromagnetic influences must be taken into account. They are less suitable when extremely high optical resolution, a very compact low-cost solution or simple magnet-based angle measurement is the main priority. The measurement principle should also be compared with alternatives where a suitable optical encoder, potentiometer or magnetic sensor can be integrated more cost-effectively.
What advantages do inductive rotary position sensors offer over magnetic or optical systems?
Inductive rotary position sensors offer particular advantages over magnetic or optical systems in terms of robustness, service life and reliability in demanding environments. Because they operate without contact, there is no mechanical wear on the sensing element. They are also generally less sensitive to dust, contamination, moisture, oil, vibration and temperature fluctuations than many optical measurement systems. Compared with magnetic sensors, inductive rotary position sensors do not require a permanent magnet as the position target. This can be advantageous in applications where magnetic fields, metallic environmental influences or particularly stable signal quality need to be considered. These inductive angle sensors are therefore well suited to mechanical engineering, industrial automation, robotics, vehicle technology, construction machinery, and the energy and process industries. The most suitable technology depends on the measuring range, resolution, accuracy, installation space, output signal and environmental conditions. Althen can help select the appropriate rotary position sensor for the application.
Can inductive rotary encoders be used in harsh industrial environments?
Yes. Inductive rotary encoders can be used in harsh industrial environments when the appropriate version is selected. Because these inductive encoders operate without contact, mechanical wear is reduced, supporting long service life and high reliability. Althen inductive rotary position sensors are suitable for demanding conditions such as extreme temperatures and strong vibration. Typical applications include industrial automation, mechanical engineering, robotics, vehicle technology, construction machinery, aerospace, and the energy and process industries. Important selection criteria include measuring range, output signal, resolution, response time, mounting options and, in particular, environmental conditions such as temperature, humidity, dust and chemical influences.
