A rotary potentiometer or angle sensor measures rotational position and angular displacement. It converts rotary movement into an electrical signal and is widely used in valves, robotics, machine controls, joysticks, industrial automation, and actuator systems.
A rotary potentiometer measures angular displacement by changing resistance as the shaft rotates. The output voltage changes proportionally with the rotation angle.
Rotary angle sensors are commonly installed in valves, actuators, joysticks, robotic systems, and industrial automation equipment.
Accurate angle feedback improves control, repeatability, automation accuracy, and machine performance.
Shaft moves angularly.
Wiper position changes.
Analog signal generated.
Angular position monitored.
A rotary potentiometer contains a circular resistive track and a rotating wiper. As the shaft rotates, the output voltage changes according to the angular position.
Rotary potentiometers are used wherever angular movement, valve position, or rotary feedback must be monitored.
Exact specifications depend on rotational range, sensing technology, enclosure type, and industrial application.

Rotary position monitoring becomes more powerful when connected to industrial IoT dashboards and analytics systems.
The sensor can communicate through analog signals, PLC systems, or industrial IoT gateways.
Dashboards may show angular position, valve opening percentage, actuator rotation, and movement history.
