BRIEF HISTORY  ---- hallpotŪ angle sensors for measuring rotational angle were developed starting in 1979 by the engineer / owner of Elweco, Inc. This technology  is based on the principle discovered by Hall more than one hundred years ago. Originally, they were designed to improve the reliability and safety of joysticks used on electric wheelchairs. From this early application that required exceptional reliability and safety considerations, they evolved as angle position sensors for industrial and military equipment as a result of their reliability and repeatability.

APPLICATIONS --- hallpotŪ angle sensors are designed and built to be used in normal or severe environments where failure of the sensor must not occur. They are intended to replace resistive potentiometers, RVDTs, resolvers, and other types of rotation sensors. They may be filled with oil and used in high pressure or underwater environments. Typical systems include control of throttles, airfoils, hydrofoils, cameras, dancer loops, antennas, automobile suspensions, steering, weapons, valves, Automobile Test Dummies, or in any system that requires accurate and reliable measurement of angular rotation

PERFORMANCE FEATURES --- All versions of hallpotŪ angle sensors  generate their signals by moving a magnet near a hall-effect sensor. Rotation of a magnetic fiels generates an electrical output signal that is an accurately controlled function of input angular position. There is no contact between the magnet and sensor such that there are no unwanted wear functions to affect the signal. Expected operational life is exceptionally long and depends only on the grade of bearings within the devices.

MECHANICAL CONFIGURATIONS --- hallpotŪ angle sensors are nearly identical to the mechanical configurations of existing devices such as servo-mount and resistive potentiometers. This enables them to replace the existing devices without redesign of the user's mounting configurations. Additionally, Elweco, Inc makes special configurations to fit non-standard or unusual geometry of the user.
