A microcomputer controlled approach velocity (differential distance) sensor and measurement system based on ultrasonic principle is presented. The measurement system is independent of any variation in atmospheric conditions, provided the target and sensor are subjected to the same atmospheric conditions. The system avoids need of recalibration, which is common in other methods implemented using compensating elements. It has got simplicity of design with low cost components and high potential accuracy. The sensor is compact and can be mounted on a robot gripper or on a CNC machine. The proposed system is suitable for usually encountered gripper velocities, since response time of the system is of the order of 25 ms for a target to gripper distance of 3 meters.
