Rotary Position Sensors

Positek offers an extensive range of rotary position sensors; an ideal non-contact alternative to the rotary potentiometer, suitable for high-precision angle measurement in a host of industrial applications


Our rotary position sensors boast the kind of accuracy and cycle-life that cannot be matched by an angular position rvdt sensor. Using our patented, inductive sensor technology, they also operate without wear or interference in all applications, offering unrivalled reliability, and exceptionally accurate angle measurement, even in the harshest of environments. 

Offering angular position measurement capabilities from between 5° and 160°, our rotary sensors have been used in rotation angle applications such as industrial valves and waterjet propulsion systems. 

With over 25 years’ experience as a rotary position sensor manufacturer, and using our onsite production facility, Positek has the flexibility to manufacture or customise any rotary position transducer to your exact requirements. Unlike many rdvt manufacturers, we can also have your rotary position sensor dispatched in as little as 1-2 working days.

The Uses of A Rotary Position Sensor

A rotary position transducer functions with better precision and longer life when designed with patented, inductive sensor innovation. This device provides incredibly precise angle measurement even when used in hazardous conditions. To measure the object’s angle and position, the moving object is attached to a sliding element of a rotary potentiometer. As the object moves, the situation of the slider attached on the sensor likewise transforms so that the resistance between the settled point and the slider changes. In this way, the adjustment in voltage corresponds to the adjustment in the displacement of the object.

Where can you find rotary position sensors being used?

Also called an rvdt sensor, it produces electrical outputs in respect to shaft revolution to calculate and measure angles accurately. This device can be utilised as part of various position-detecting applications such as car position sensing, equipment position sensing, throttle position detecting, steering wheel position detecting, and pedal position sensing. It can also be used for industrial control, damper control, and valve control. When used on a car, a rotary potentiometer gives measurements with the help of two rotating magnets on different gears to identify the angular rotation of the wheel.

What angles can rotary position sensors measure?

There are different types of rotary position sensors and each has its own features, specifications, and capabilities that range from 5° and 160°. For instance, the measurement range of a miniature rotary position transducer is any angle from ±15° to ±70°. Meanwhile, a slim-line rotary position sensor has a measurement range of any angle from ±7.5° to ±80°. In addition to this, a large rotary position transducer can measure any angle from ±8° to ±80°. If you’re wondering about the measurement range of a large, submersible rotary sensor, it’s basically the same as the slim-line, which can measure any angle from ±7.5° to ±80°.

Can a rotary position transducer be customised to my requirements?

If you cannot find a design for a rotary position sensor that suits your requirements, it may be customised according to your needs. You can simply contact your trusted sensor supplier and specify the measurements and custom design you need for your sensor. Discussion with an engineering team will help you to build a customised rotary potentiometer that is compatible with the features and how your equipment is configured.

A rotary position sensor works on the same principle as a transformer and is one of the most crucial devices used in modern machinery. It serves many purposes and without it, modern machines would not be able to function with such high precision and quality.
