Non-Contacting Linear Position Sensors

Non-Contacting Linear Position Sensors are a type of measuring instrument which is commonly used in many industries for various applications.

There are many different types of Non-Contacting Linear Position Sensors available, they use different technologies, and the advantages they have in common are;

• Wear-free
• Long life
• Little to no maintenance required
• Consistent excellent performance
• Fast response time
• Well suited to a wide range of applications and environments

Non-Contacting Linear Position Sensor Types

Some of the different types of non-contacting linear position sensor technologies are;

Positek PIPS - our sensing technology (Positek inductive Position Sensor) is a fully non-contacting technology and works similarly to LVDTs. It uses high-frequency coils and has fewer turns than that of an LVDT. PIPS also offer a better stroke-to-length ratio than LVDTs and has built-in signal conditioning, so no additional devices are required.

PIPS measurements are highly accurate and reliable. We have ranges for various environments with the required certifications; intrinsically safe environments and submersible sensors. Contact us for more information.

Ultrasonic Position Sensors ultrasonic position sensors use ultrasonic sound waves which are emitted from the device and bounced back. The feedback to the sensor is measured to determine the position of an object.

LVDTs - (Linear Variable Differential Transformers) are like PIPs sensors, they use wound coils and core to take high-accuracy measurements in a non-contacting fashion.

Eddy Current Eddy Current Sensors use an inductive measurement method using oscillating circuits and alternating magnetic currents to determine position.

Laser Sensors Laser sensors work similarly to ultrasonic sensors; they emit a laser and determine the position of the object by measuring the feedback received by the sensor.

Non-Contacting Linear Position Sensor Application
