ABSTRACT:
A radioisotope proximity sensor is provided for detecting proximity or distance to a nearby object containing a small radiation source complementary to the sensor. The output of the sensor is amplified or compared to determine the distance or proximity. The radioisotope proximity sensor is unaffected by magnetic fields over the short sensing distances. It is also unaffected by environmental contamination when the appropriate radiosource/detector combination is used. The radioisotope proximity sensor is easily shielded from electrostatic or electromagnetic noise, and the radiation source can be small, easily incorporated, and requires no external power or connections to affect mechanical reliability or impede armature movement.
