The measurement range of the infrared detector 121 is greater than or equal to 6 meters.
The length of the pipe die is more than ten meters, and the offset amplitude of the head end of the pipe die close to the motor is often smaller than the offset amplitude of the end of the pipe die far away from the motor.
